Troubleshooting
The motor does not rotate
Category
Parameters
Wiring
Installation
Cause
The control mode is not correctly
selected.
The torque limit of the parameter is set
to 0.
The motor does not run because the
zero speed clamp is open (OFF).
The internal speed setting parameter
hasn’t been entered.
The circuit for CW/CCW overtravel
inhibit input of CN X5 is open.
Servo-ON signal of CN X5 has not been
activated.
The deviation counter input of CN X5 is
turned ON (shorted).
Command input connection is wrong
when pulse input form of CW and CCW
is selected in the position control mode.
The motor output shaft is heavy and
does not turn.
Action
Check the value of the control mode setting Pr02.
0… High velocity positioning control
1… Internal velocity control
2… High function positioning control
Check the value of the torque limit set-up Pr5E.
Change it to a pre-shipment default of 300.
Check the value of the ZEROSPD/TC input selection Pr06, and
change it to 0.
Zero clamp function is enabled when it is set to 1. Otherwise,
change the setting to 1 and enable the zero speed clamp input.
Then, correct wiring connections so that the zero speed clamp
input can turn ON successfully.
Check settings of Pr53 to Pr56.
Set desired rotation speed.
Check the value of Pr04. If it is 0, connect between CN X5 pins
8 and 13, and 7 and 13.
Short circuit (ON) between the connector CN X5 pins 2 and 13.
Open (OFF) between the connector CN X5 pins 4 and 13.
Connect so that the photocoupler inside the driver is turned
OFF on the side in which pulse is not input (See Pages 73 to
81).
Power OFF and disconnect the motor from the installation.
Turn the motor shaft by hand to see if it can rotate. If the motor
is provided with electromagnetic brake, turn the shaft by hand
while applying voltage to the brake (DC24V). If the motor shaft
does not rotate, ask the sales agent of the motor for repair.
