• Increase this setting slowly in steps of 0.1 if overvoltage (ov) or undervoltage (Uv1) occurs at the beginning of deceleration
while KEB Ride-Thru 2 is enabled or Intelligent Stall Prevention during deceleration is activated.
• If this setting is too high, then a fair amount of speed or torque ripple can result.
Adjustment for Overvoltage Suppression
• Increase this setting slowly in steps of 0.1 if overvoltage suppression is enabled (L3-11 = 1) and a sudden increase in a
regenerative load results in an overvoltage (ov) fault.

n Overvoltage Suppression Function
This function suppresses overvoltage faults by slightly increasing the output frequency when the DC bus voltage rises. It can
be used to drive loads with cyclic regenerative operation, such as punch presses or other applications that involve repetitive
crank movements.
201
5.8 L: Protection Functions
The output frequency is adjusted during ov suppression so that the DC bus voltage does not exceed the level set in parameter
L3-17. In addition to the parameters explained below, ov suppression also uses these settings for frequency adjustment:
• DC bus voltage gain L3-20
• Deceleration rate calculations gain L3-21
• Inertia calculations for motor acceleration time L3-24
• Load inertia ratio L3-25
Note:
1. The motor speed will exceed the frequency reference when overvoltage suppression is triggered. Consequently, overvoltage suppression
is not appropriate in applications that require a perfect match between the frequency reference and the actual motor speed.
2. Disable overvoltage suppression when using a braking resistor.
3. Overvoltage may still occur if there is a sudden increase to a regenerative load.
4. This function is enabled only when operating just below the maximum frequency. Overvoltage suppression does not increase the output
frequency beyond the maximum frequency. If this is required by the application increase the maximum frequency and change the base
frequency setting.
n L3-24: Motor Acceleration Time for Inertia Calculations
Sets the time it takes to accelerate the motor from stop to the maximum speed at motor rated torque. This parameter should
be set when using KEB Ride-Thru 2, Intelligent Stall Prevention during deceleration (L2-04 = 2), or the overvoltage suppression
function (L3-11 = 1).

Note:
When overtorque occurs in the application, the drive may stop due to overcurrent (oC) or overload (oL1). To prevent this, an overload
situation should be indicated to the controller before oC or oL1 occur in the drive. Use the torque detection for this purpose. Use undertorque
detection to discover application problems like a torn belt, a pump shutting off, or other similar trouble.

Setting 3: Alarm Only
If an overheat alarm occurs, an alarm is output and the drive continues operation.
Setting 4: Operation with Reduced Speed
If an overheat alarm occurs, the operation is continued but the speed is reduced to the level set in parameter L8-19. If after 10
s the oH alarm is still present, the speed is reduced once more. The amount of reduction depends on how often the alarm
repeats. If the oH alarm disappears while the drive is operating at a reduced speed, then the drive will switch back to the
previous speed it was reduced to before. Figure 5.78 explains the operation with reduced speed during an oH alarm. A digital
output programmed for 4D is switched when the oH alarm is still active after ten reduction cycles.

n P1-03: Feedback Device Scaling
Sets the feedback device scaling used for the PID controller. This information can be found on the nameplate or specification
sheet and is usually expressed as the maximum output of the device.
For example, a pressure sensor scaling might be 145.0 PSI at 20 mA output and would require setting P1-03 to 145.0 PSI.

the standard acceleration rate.
n P4-12: Thrust Bearing Frequency
Sets the frequency used by the drive when determining which acceleration and deceleration time to use. The Thrust Bearing
function is used for applications using submersible motors. The function provides an alternate acceleration time (P4-11) and
deceleration time (P4-13) for protecting the pump bearings.
At start, the drive will use the P4-11 acceleration time until the P4-12 frequency is reached, at which time it will use the active
C1-oo acceleration and deceleration times. At stop, if the output frequency is above the P4-12 setting, the active C1-oo
deceleration time will be used until the P4-12 setting is reached at which time it will use the P4-13 time setting for the rest of
deceleration.
If P4-12 is set greater than P1-06 (minimum Pump Speed), P4-12 will become the frequency lower limit. The drive PID control

This is useful in preventing a peak power surge when multiple drives power up and begin accelerating simultaneously. This
function works when the drives all have different P4-17 settings to spread out the power draw during acceleration.
If the Run command is removed and re-applied during the P4-17 time, the drive will cancel the utility start delay and
immediately begin running.

The drive Analog PI feedback signal and status are sent to the iQpump MEMOBUS network. The status is dependent on b5-12,
PI Feedback 4 to 20 mA Detection, that is run in the background per drive. If the status is good and the drive is the current
Lead drive, that feedback signal is used as the Network PI Feedback and is constantly sent to all the drives in the network.
When the current Lead drive does not have a good status, the Network PI Feedback is taken from another drive that has a good
status.
When there is no Analog Feedback signal for PI Feedback, the drive uses the Network PI Feedback register when it is allowed
and an alarm can flash if desired.
When P1-01 is set to 3, b5-12 > 0, and the PI source is 4 to 20 mA, the analog feedback detection process starts automatically
for all drives that have P9-02 ≠ 3 and are ready to run on the network as soon as one of the drives receives a Run command
is not running in Pre-charge mode. Drives that fail on the feedback detection will indicate that their feedback signals are invalid
and will not be considered by the iQpump MEMOBUS Network as good sources. The network reads out the valid signals
selected using lead-drive priority, and sends it back to all the drives as the Network PI Feedback. If the current lead drive has
a valid analog feedback signal, it will be the Network PI Feedback signal. Otherwise, the Network PI Feedback signal is set
to a drive with a good analog signal based on the Drive Discovery of the iQPump Memobus Network. In both cases, a status
bit is also sent out indicating that the network has a good feedback source.
b5-12 = 1: Instead of alarm, NetwrkFB Lost message
b5-12 = 2: Instead of fault, NetwrkFB Lost message, drive will not accept iQpump Network run commands, and the stopping
method is fixed to coast-to-stop.
Any drive with b5-12 set to 0 and P9-02 ≠ 3 will effectively have no feedback loss detection and will continuously send the
Analog PI Feedback to the iQpump Network regardless if it is a healthy signal.
When b5-12 is set to 2 and P9-02 ≠ 3, PI Feedback detection will cause an alarm instead when one of the following conditions
exists:
• The drive is in HAND Mode
• There is no Lead drive on the network
• The drive is not in AUTO Mode
Setting 0: Analog only
The drive will never read the Network PI Feedback register as the feedback source, although the drive will still transmit its
own PI Feedback signal to the network. The feedback detection is based on parameter b5-12.
Setting 1: Ana->Net, No alarm
The drive reads the Network PI Feedback register if the analog feedback detection determines a signal loss. If the network
feedback signal is also invalid, it will act according to b5-12. Setting b5-12 to 0 or using a non-4 to 20 mA PI Feedback signal
disables analog feedback detection and prevents the drive from switching to the Network PI Feedback.
Setting 2: Ana->Net, Alarm
The drive reads the Network PI Feedback register if the analog feedback detection determines a signal loss. In addition, an
alarm will be displayed indicating that the analog has been lost, and that the feedback source is now the network. If the network
feedback signal is invalid as well, it will act according to the b5-12 setting. Setting b5-12 = 0 or using a non-4 to 20 mA PI
Feedback signal disables analog feedback detection and prevents the drive from switching to the Network PI Feedback.
Setting 3: Network only
The drive will always read the Network PI Feedback register.

as the first pump that was run in the system and the Last drive is defined as the Lead Drive. When the timer expires, the drive
is removed from the system, turned-off, and a new lead drive is brought online to replace it.
Alternation is enabled when P9-03, Alternation Time, is set to a non-zero value. In FIFO, the timer is run on the first drive
and in LIFO it is on the lead drive. When the timer expires, the drive requests alternation based on the P9-04 setting and sends
that information to the MEMOBUS network.
Setting 0: First in, first out auto
