Wiring
Causes
The gains are not appropriate.
Position commands are not
stable.
CN I/F signals are chattering.
1) Servo-ON signal
2) Counter clear input signal
3) Zero speed clamp input

Countermeasures
Increase the value of Pr11 (1st velocity loop gain).
Set a torque filter (Pr14) and then further increase
the value of Pr11.
Check the behavior of the motor on the waveform

“
using the CN MON
check pin. Check the wiring and its connections.
Check the controller.
1) Check the wiring and connections between CN I/F pins 2
and 13 by monitoring the display of input and output sig-
nals status. Modify the wiring so that Servo-ON signals
can be made active correctly. Check the controller.
2) Check the wiring and connections between CN I/F pins 4
and 13 by monitoring the display of input and output sig-
nals status. Modify the wiring so that the position error
counter clear input can be made active correctly. Check
the controller.
3)
Check the wiring and connections between CN I/F pins 5 and
13, 4 and 13, and 6 and 13 by monitoring the display of input
and output signals status. Modify the wiring so that Zero Speed
Clamp input can be made active correctly. Check the control-
ler.
