The control mode selected is not
correct.
The torque limit has been set to 0.
The zero speed clamp is ON, so
the motor does not operate.
Internal velocity set-up parameter
is not entered.

Check the value of Pr02 (control mode set-up).
0: position control, 1: internal velocity control,
Check the value of Pr5E (torque limit set-up).
Change the value to 300 (default).
Check the value of Pr06 (ZERPSPD input selection).
Change the value to 0. If the value is 1, the zero
clamp function is valid. If you desire to set the pa-
rameter to 1, enable the zero speed clamp input,
and adjust the wiring so that the zero speed clamp
input can be turned on correctly.
Check the values of Pr53 through Pr56.
Set a desirable number of revolution.
Check the value of Pr04. If the value is 0, connect
between CN I/F pins 8 and 13, and 7 and 13.
Connect (short circuit) between CN I/F pins 2 and
1 3 .
Disconnect between CN I/F pins 4 and 13.
Turn off the power. Disconnect the motor. Rotate
the motor shaft by hand to make sure that the mo-
tor rotates freely. If the motor is fitted with an elec-
tromagnetic brake, rotate the shaft by hand while
applying a voltage (24VDC) to the brake. If the mo-
tor does not rotate, consult the sales agent to re-
pair it.
