is too high. the motor.
The phase-to-phase voltage of the
motor is insufficient.
Use a motor that can withstand
phase-to-phase voltages surges
greater than the maximum surge
voltage.
Only use motors suitable for
apllications with inverters.
Connect the AC reactor to the
inverter output (set the carrier
frequency to 3 kHz).
The motor fan has stopped or the fan
is obstructed with debris.
Check the motor fan and remove
any foreign objects.
The motor
stops during
acceleration.
The load is too high.
Reduce the load.
Increase the volume of the torque
boost.
Replace the motor and the inverter
with models with capacity
appropriate for the load.
The current is too big.
If the output current exceeds the
rated load, decrease the torque
boost.
The motor
stops when
connected to
load.
The load is too high.
Reduce the load.
Replace the motor and the inverter
with models with capacity
appropriate for the load.
The motor does
not accelerate.
/The
acceleration
time is too long.
The frequency command value is low. Set an appropriate value.
The load is too high.
Reduce the load and increase the
acceleration time. Check the
mechanical brake status.
The acceleration time is too long. Change the acceleration time.
The combined values of the motor
properties and the inverter parameter
are incorrect.
Change the motor related
parameters.
The stall prevention level during
acceleration is low.
Change the stall prevention level.
The stall prevention level during
operation is low.
Change the stall prevention level.
