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
graphic screen of PANATERM
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.
