Troubleshooting
Torque limiting value is not
increased.
●
The value set in the "Torque limiting maximum value" parameter is exceeded.
▷
Reconsider the setting value of the "Torque limiting maximum value" parameter or
operation data.
Torque cannot be limited.
●
If the TL input is turned OFF, the torque limiting function is disabled.
▷
Check the connection and the ON-OFF status of signal.
The signal input status can be checked using the internal I/O monitor or D-I/O monitor.
The PWR/ALM LED blinks in
orange.
●
Information is present.
▷
Information is present because of any of the causes.
Check the generated information using the information monitor or internal I/O monitor,
and clear the cause of generation or disable the "INFO action" parameter.
The motor rotates in the
opposite direction to the
specied one.
●
The ON-OFF operation of the FWD/REV input is used wrongly or the FWD/REV
input is not connected correctly.
▷
Check the connection and the ON-OFF status of signal.
The signal input status can be checked using the internal I/O monitor or D-I/O monitor.
●
The setting of the "Motor rotation direction" parameter has been changed.
▷
The motor rotates in the forward direction when the FWD/REV input is turned ON.
The setting for rotating in the forward direction can be set with the "Motor rotation
direction" parameter.
(Initial value: +=CW)
●
The gearhead with a reduction ratio which rotation direction is opposite to the
motor output shaft is used. (Refer to p.19 for the rotation direction of the gearhead
output shaft)
▷
Reverse the ON-OFF status of the FWD/REV input or invert the logic level setting of the
input.
Change the setting for the "Motor rotation direction" parameter.
●
A hollow shaft at gearhead is used.
▷
The hollow shaft at gearhead rotates in the opposite direction to the motor when
viewed from the front side of the gearhead, and rotates in the same direction to the
motor when viewed from the rear side (motor mounting side).
• The motor movement is not
stable.
• Motor vibration is too large.
●
The motor and gearhead output shaft and a load shaft are out of alignment.
▷
Check the coupling condition of the motor and gearhead output shaft and the load
shaft.
●
The motor output power and the driver output power are not matched.
▷
Check if the motor output power and the driver output power are the same.
The driver output power can be checked by the driver model name in the unit
information monitor.
●
The product is aected by electrical noise.
▷
Check the operation using the motor, driver and a minimum of external equipment
required for operation.
If an eect of noise has been conrmed, implement the following countermeasures:
[Keep away from the noise sources.] [Reconsider the wiring.]
