Phenomenon
Possible cause
Remedial action
Motor vibration is too large.
The load is small.
Lower the current with the “Base current” parameter. If
the motor output torque is too large with respect to a
load, vibration will increase.
The “Main power mode” parameter
is set wrongly.
Check the setting of the “Main power mode”
parameter.
The main power supply starts up
slowly or the voltage of the main
power supply is unstable.
Set the “Main power mode” parameter to “0: 24 VDC” or
“1: 48 VDC” according to the rated voltage of the main
power supply.
The electromagnetic brake is
not put into a state of releasing
the motor shaft.
The power is not supplied to the
electromagnetic brake.
Check the connection of the electromagnetic brake.
A voltage for the electromagnetic
brake is insufficient.
Make the input voltage of the control power supply
higher than 22.8 VDC.
When an alarm is being generated, check the alarm message via RS-485 communication or using the
MEXE02
.
