ZETADYN 3BF. Operating instruction (Part.-No. 00163264-GB 2/200)

Emergency evacuation

12.1

Evacuation with 1-phase mains supply 230V AC

Information

The methods of Emergency Evacuation, described in this chapter, are only possible with the types

ZETADYN 3BF011 - ZETADYN 3BF074.

Due to the low power requirements of a synchronous drive, it is possible to carry out an evacuation trip

in the motoric and generatoric direction.

Due to the high level of magnetization current, emergency evacuation with a single-phase mains

supply with asynchronous motors does not make sense.

Characteristics of evacuation with single-phase mains supply:

• Evacuation in motoric and generatoric direction

• Load-independent starts

• Load-independent stopping

• Flush stopping

If there is a mains failure, the mains supply must provide the following voltage to the inverter:

•

230 VAC to feed L1 and L2

The frequency inverter analyses the load ratio between the car and the counterweight during every

start.

The control system starts the evacuation trip by activating:

• Controller enable

• Direction default

• Speed default

Size of the voltage supply

The required performance consists of the following:

Electronic frequency inverter power consumption

+ Control systempower consumption

+ Electromechanical brakes power consumption

+ Other consumers (car light, …) power consumption

Motor power consumption during motoric operation with sufficient power

(ask motor manufacturer)

= Real power [W]

Information

The shaft efficiency has a decisive influence on the required power of the single-phase mains supply.

12.2

Evacuation with UPS

Information

The methods of Emergency Evacuation, described in this chapter, are only possible with the types

ZETADYN 3BF011 - ZETADYN 3BF074.

Due to the low power requirements of a synchronous drive, it is possible to carry out an evacuation trip

at half-load or in the direction of the pulling load using a commercially available UPS. An evacuation

trip against the load direction is not possible!

Due to the high level of magnetization current, emergency evacuation with a single-phase mains

supply with asynchronous motors does not make sense.

In case of a mains failure, the UPS supplies the following voltage:

•

230 VAC to feed L1 and L2

During each trip, the frequency inverter analyses the load ratio between the car and the counter-

weight. In case of a voltage drop (mains failure), the frequency inverter informs the control system

which direction is possible for an evacuation trip. The open loop control carries out the evacuation trip

in the corresponding direction.

The control system starts the evacuation trip by activating:

• Controller enable

• Direction preset (in the direction of the pulling load)

• Speed default

12.2.1

Evacuation through UPS with optimum power

Characteristics of evacuation with optimum UPS power:

• Load-independent starts

• Load-independent stopping

• Flush stopping

• With corresponding sizing of the UPS, a trip in the motoric direction is also feasible.

Calculation of the UPS

The required UPS performance consists of the following:

Electronic frequency inverter power consumption

+ Control systempower consumption

+ Electromechanical brakes power consumption

+ Other consumers (car light, …) power consumption

Motor power consumption for UPS operation with sufficient power (ask

motor manufacturer)

= Real power UPS [W]

Information

The shaft efficiency has a decisive influence on the required power of the UPS performance.

122/200

Emergency evacuation

12.2.2

Evacuation through UPS with minimum power

• Load-dependent starting, cannot be optimized

• Evacuation only possible in the direction of the pulling load

• Positioning is carried out load dependent; that means step formation could occur.

Calculation of the UPS

The required UPS performance consists of the following:

Electronic frequency inverter power consumption

+ Control systempower consumption

+ Electromechanical brakes power consumption

+ Other consumers (car light, …) power consumption

Motor power consumption for UPS operation with reduced power (ask

motor manufacturer)

= Real power UPS [W]

Information

The shaft efficiency has a decisive influence on the required power of the UPS performance.

Improving the positioning

Information

The methods of Emergency Evacuation, described in this chapter, are only possible with the types

ZETADYN 3BF011 - ZETADYN 3BF074.

Due to the reduced UPS power, it is not possible to decelerate the motor until standstill. That means,

at the time when the floor is reached and the brakes are closed, the motor is still moving. The time

delay until the brakes are closed can lead to overshooting the door zone area and thus step formation.

Stop before floor level

The brakes are already closed when the distance to

Information

The positioning is still load-dependent despite this measure. When travelling at half load, the elevator

can stop too early outside the door zone range with parameter set 2/STOP = ON.

12.5

Emergency evacuation by opening the brakes

Information

The methods of Emergency Evacuation, described in this chapter, are only possible with the types

ZETADYN 3BF011 - ZETADYN 3BF074.

Emergency evacuation through manually or electrically opening the motor brakes until the cabin has

reached the next floor in the direction of the pulling load.

Warning

If an emergency evacuation is carried out by opening the brakes, the motor windings must be

short-circuited for the evacuation to prevent an uncontrolled acceleration of the elevator. The

short-circuit generates a speed-dependent braking torque, sufficient in most cases to limit the

elevator speed to a safe level.

Caution!

Short-circuiting of the motor windings must be permitted by the motor manufacturer. This is tested and

Error diagnosis

13.1

Travel abort and acknowledgement during malfunctions

13.1.1

Travel abort

If the frequency inverter detects an error, the actual travel program is aborted and following outputs

are switched off immediately:

• ST - Malfunction

• RB - Controller ready (motor contactors)

• MB - mechanical brake

The open loop control must immediately:

• Close the electromechanical brake

• Open the motor contactors

The machine is decelerated by the brake torque of the mechanical brake.

The error that has occurred is shown in the display with error text and error number. LED’s, error

memory and an error list are available for additional troubleshooting.

13.1.2

Acknowledgement

Acknowledging the error is performed automatically 2 seconds after the cause of the error has been

repaired.

The prerequisite is that the input signals for traveling speeds are applied. No error acknowledgement

is issued f traveling signals are applied before the expiration of the 2 seconds.

The following errors are not automatically acknowledged:

Masc-Funktion

You can deactivate individual monitoring functions by inputting an item in the error mask (see

"Parameter list/Monitoring" menu chapter). To do this, enter the corresponding error number into error

masks 1-5.

The maskable errors are marked in the error list with a point in thecolum n M.

Caution!

CAUTION!

Never use the mask function during trouble shooting and error diagnosis. You must acknowl-

edge the cause of the error for permanent inverter operation!

Sequential errors can occur if errors are masked.

The masking deactivates important monitoring functions. This may result in dangerous operat-

ing states or damage to the inverter.

13.5.2

Block function

Blocks the controller if certain errors occur several times is succession. The errors must occur in

directly consecutive travel tests. The fault counter is set to 0 when performing a trouble-free run.

The following block functions can be set in the Monitoring / MOD_ST menu:

• Fix 2 Sec.: No blocking function, the output configured on "ST" drops for 2 seconds during a

malfunction and then increases again (speed preset V_x must be switched off)

• Lock n.3: Lock function after 3 malfunctions. Output "ST" remains dropped after the 3rd error

• Lock n.2: Lock function after 2 malfunctions. Output "ST" remains dropped after the 2rd error

• Lock n.1: Lock function after 1 malfunction1. Output "ST" remains dropped after the 1st error

Errors that lead to a blocking of the frequency inverter are marked with a point in column S.

Stand-by function frequency converter

To save energy at standstill the frequency inverter ZETADYN 3 can be switched to stand-by mode.

Internal components of the frequency inverter are switched off in stand-by mode. This means that the

frequency inverter has a much lower power loss at standstill. There are two stand-by modes in the

ZETADYN 3:

• Standby 1

• Standby 2

appears in the display.

Information

Only change the clock frequency after consultation with the ZIEHL-ABEGG hotline. Consulta-

tion can clarify the effect of changing the clock frequency on the service life of the frequency

inverter.

Caution!

Increasing the clock frequency causes

CAUTION!

• a performance reduction of the frequency inverter (see Technical Data chapter)

• a greater power loss and thus increased heating of the frequency inverter

The service life of the frequency inverter is negatively influenced by the higher temperatures.

15.1.1

Fixed presetting of the clock frequency (Menu Power sectionl/M_PWM=Fix f_PWM)

The cycle frequency of the frequency inverter is 8 kHz after setting at the factory. This can be

Encoder offset-alignment

Caution!

CAUTION!

Make sure you perform an encoder alignment if you operate a synchronous motor. Operating

the motor without encoder-offset alignment can cause uncontrolled motor movements.

Traveling is prohibited before an absolute encoder offset alignment has been performed!

Information

In ZIEHL-ABEGG motors, the absolute value encoder is already calibrated to the offset value

"0" ex works.

It is no longer necessary to perform an absolute encoder offset alignment!

151/200

Special functions

Options for calibrating an absolute value encoder

The frequency converter ZETADYN 3BF has two different methods of calibrating the absolute value

encoder:

• load-free calibration of theabsolutevalue encoder

• calibration of the absolute value encoder with brake closed

General conditions required for an encoder alignment without load:

• The installation and motor data must be configured

• Load-free operation (ropes must be removed from the traction sheave)

• Brake monitoring must be activated corresponding to the number and type of brakes in use (

Monitoring/BR menu)

• Contactor monitoring must be configured according to the type of contact for monitoring (Monitor-

ing/CO menu)

•

General conditions required for an encoder alignment closed brake:

• The installation and motor data must be configured

• It must be ensured that the brake does not open during the calibration (disconnect brake)

• Brake monitoring must be activated corresponding to the number and type of brakes in use (

Monitoring/BR menu)

• Contactor monitoring must be configured according to the type of contact for monitoring (Monitor-

ing/CO menu)

15.2.1

Load-free alignment SSI-Encoder

When aligning the SSI encoder, the frequency inverter supplies the motor with direct current. During

this, the rotor jumps to the middle of the nearest magnetic poles. In this rotor position, the absolute

rotary encoder must be manually aligned to its zero point. To ease installation, it is recommended to

connect the encoder to the frequency inverter before installation and to align the offset value "0"

(value in Encoder-adjust./ENC_POS menu). After that, mount the encoder into position - shifting as

little as possible - into the position in which the terminal screw is easily accessible.

Information

The calibration should always be done twice. Any inaccuracy in the 1st calibration is detected by the

2nd calibration and can be corrected.

If the encoder terminal screw is not accessible in the "ENC_POS = 0" position, the encoder can be

adjusted to the value of any pole pair (see table).

Checking the load-free alignment of the SSI- & EnDat-encoders

When checking the encoder offset, the frequency inverter supplies each individual pole in the motor

with direct current. The offset is determined on each pole and the average offset is calculated from

that. This offset can be stored in the frequency inverter.

Information

The offset determined during the inspection is not stored in the frequency inverter because if the

inverter is replaced, the new inverter will not have the identical encoder offset. You must carry out a

new encoder offset alignment or enter the old encoder offset.

Information

During the encoder offset alignment, the driving disk must turn to the right (when looking at

the driving disk). Once the alignment is complete, the driving disk must be located in the same

position as at the start of the process.

To save the result, a memory card needs to be in the X-MMC card slot during the check.

Rotary encoder calibration with closed brake

If the encoder is calibrated with the brake closed, there is no need to take the cables off the traction

sheave. This allows calibration to be performed with much less effort.

Caution!

The electric brake of the motor must not open during the encoder offset alignment!

CAUTION!

It is recommended to remove the electrical connection of the brake for the duration of the

encoder offset alignment!

Information

Considerable noise may occur at the motor for approx. 10-15 s during alignment. These noises

are caused by the special form of energization of the motor and are normal for this kind of

encoder offset alignment.

Pleas keep the button for the inspection travel still closed!
