Safety Information

NOTICE

Use an inverter-duty motor or vector-duty motor with reinforced insulation and windings

applicable for use with an AC drive.

If the motor does not have the correct insulation, it can cause a short circuit or ground fault from insulation

deterioration.

When you touch the drive and circuit boards, make sure that you observe correct electrostatic

discharge (ESD) procedures.

If you do not follow procedures, it can cause ESD damage to the drive circuitry.

Do not do a withstand voltage test or use a Megger insulation tester on the drive.

These tests can cause damage to the drive.

Do not operate a drive or connected equipment that has damaged or missing parts.

You can cause damage to the drive and connected equipment.

Do not use steam or other disinfectants to fumigate wood for packaging the drive. Use

alternative methods, for example heat treatment, before you package the components.

Gas from wood packaging fumigated with halogen disinfectants, for example fluorine, chlorine, bromine, iodine

or DOP gas (phthalic acid ester), can cause damage to the drive.

◆ Warning Label Content and Location

The drive warning label is in the location shown in Figure i.1. Use the drive as specified by this information.

Note these points when you use this function:

• When you can decouple the motor and machine for a test run, use Rotational Auto-Tuning. You must make adjustments to the

control in the range where there is no vibration in the machine after Rotational Auto-Tuning.

• Motor loss increases during overexcitation braking and high-slip braking. Use a maximum braking frequency of 5% ED and a

maximum braking time of 90 seconds. After you start high-slip braking, you cannot restart the motor until it stops. Use

overexcitation braking to decelerate over a shorter time at a pre-determined speed.

Note these points when you use this function:

• When you can decouple the motor and machine for a test run, use Rotational Auto-Tuning. You must make adjustments to the

control in the range where there is no vibration in the machine after Rotational Auto-Tuning.

• For vector control, use a 1:1 drive to motor ratio. You cannot use vector control when more than one motor is connected to one

drive. Select a drive capacity so that the motor rated current is 50% to 100% of the drive rated current. If the carrier frequency is

too high, the drive rated current is derated.

• Motor loss increases during overexcitation braking and high-slip braking. Use a maximum braking frequency of 5% ED and a

maximum braking time of 90 seconds. After you start high-slip braking, you cannot restart the motor until it stops. Use

overexcitation braking to decelerate over a shorter time at a pre-determined speed.

• Acceleration and deceleration have priority over torque limits in Open Loop Vector Control during acceleration and deceleration

(soft start changes). The drive will not operate until the speed is at the minimum frequency or the reverse direction of motor

rotation when the motor speed decreases because of torque limits during constant speed control. Set L7-07 = 2 [TrqLimit@Acc/

Decel = I-ctrl@Ac/Dec] to enable torque limits during acceleration/deceleration (for winding applications).

Do not use this function with hoist application.

Removing/Reattaching Covers

DANGER! Electrical Shock Hazard. Do not examine, connect, or disconnect wiring on an energized drive. Before servicing,

disconnect all power to the equipment and wait for the time specified on the warning label at a minimum. The internal capacitor

stays charged after the drive is de-energized. The charge indicator LED extinguishes when the DC bus voltage decreases

below 50 Vdc. When all indicators are OFF, measure for dangerous voltages to make sure that the drive is safe. If you do work

on the drive when it is energized, it will cause serious injury or death from electrical shock. The drive has internal capacitors that

stay charged after you de-energize the drive.

◆ Remove the Front Cover

1. Use a slotted screwdriver to unlock the front cover of the drive.

Use a slotted screwdriver with a tip width of 2.5 mm (0.1 in) or less and a thickness of 0.4 mm (0.02 in) or

less.

3.1 Safety Precautions

WARNING

Do not use the main circuit power supply (Overvoltage Category III) at incorrect voltages.

Operate the drive in the specification range of the input voltage on the drive nameplate.

Voltages that are higher than the permitted nameplate tolerance can cause damage to the drive.

When you install a dynamic braking option, wire the components as specified by the wiring

diagrams.

Incorrect wiring can cause damage to braking components or serious injury or death.

NOTICE

Do not let unwanted objects, for example metal shavings or wire clippings, fall into the drive

during drive installation. Put a temporary cover over the drive during installation. Remove the

temporary cover before start-up.

Unwanted objects inside of the drive can cause damage to the drive.

Obey correct electrostatic discharge (ESD) procedures when you touch the drive.

Incorrect ESD procedures can cause damage to the drive circuitry.

Select a motor that is compatible with the load torque and speed range. When 100% continuous

torque is necessary at low speed, use an inverter-duty motor or vector-duty motor. When you

use a standard fan-cooled motor, decrease the motor torque in the low-speed range.

If you operate a standard fan-cooled motor at low speed and high torque, it will decrease the cooling effects and

can cause heat damage.

Obey the speed range specification of the motor as specified by the manufacturer. When you

must operate the motor outside of its specifications, contact the motor manufacturer.

If you continuously operate oil-lubricated motors outside of the manufacturer specifications, it can cause damage

to the motor bearings.

When the input voltage is 440 V or higher or the wiring distance is longer than 100 m (328 ft),

make sure that the motor insulation voltage is sufficient or use an inverter-duty motor or vector-

duty motor with reinforced insulation.

Motor winding and insulation failure can occur.

Before you connect a dynamic braking option to the drive, make sure that qualified personnel

read and obey the Braking Unit and Braking Resistor Unit Installation Manual

(TOBPC72060001).

If you do not read and obey the manual or if personnel are not qualified it can cause damage to the drive and

braking circuit.

3

Make sure that all connections are correct after you install the drive and connect peripheral

devices.

Incorrect connections can cause damage to the drive.

Note:

• Torque characteristics differ compared to operating the motor directly from line power. The user should have a full understanding of

the load torque characteristics for the application.

• The rated input current of submersible motors is higher than the rated input current of standard motors. Carefully select the correct

drive capacity. When the distance between the motor and drive is long, use a wire that can connect the motor to the drive without a

reduction in motor torque.

• Do not use unshielded wire for control wiring. Use shielded, twisted-pair wires and ground the shield to the ground terminal of the

drive. Unshielded wire can cause electrical interference and unsatisfactory system performance.
