14-18
Accel./Decel. time and
the working
cycle are too short.
Increase the setting values for Pr.01-12–01-19 (accel. / decel. time).
V/F voltage is too high.
Adjust the settings for Pr.01-01–01-08 (V/F curve), especially the setting value
for the mid-point voltage (if the mid-point voltage is set too low, the load
capacity decreases at low speed).
Refer to the V/F curve selection of Pr.01-43.
The capacity of the drive is too
small.
Replace the drive with a larger capacity model.
Overload during low-speed
operation.
Reduce the load during low-speed operation.
Increase the drive capacity.
Decrease the carrier frequency of Pr.00-17.
Torque compensation is too large.
Adjust the torque compensation (refer to Pr.07-26 torque compensation gain)
until the output current reduces and the motor does not stall.
Check if the setting for stall
prevention is correct.
Set the stall prevention to the proper value.
Output phase loss
Check the status of three-phase motor.
Check if the cable is broken or the screws are loose.
Improper parameter settings for
the speed tracking function
(including restart after momentary
power loss and restart after fault)
Correct the parameter settings for speed tracking.
1. Start the speed tracking function.
2. Adjust the maximum current for Pr.07-09 speed tracking.
