10.8 Trouble shooting

Depending on the conditions in your installation, there may be a wide variety of reasons for the fault. In multi-axis
systems there may be further hidden causes of a fault.
Eliminate errors and faults in compliance with work safety rules. Troubleshooting only by
qualified and trained staff.
Detailled hints for removal of faults can be found in the

Measures to remove the cause of
the fault
use null-modem cable
plug cable into the correct sockets on the
servo amplifier and PC
select correct interface
apply enable signal
check setpoint cable
correct motor phase sequence
check brake control
check mechanism
set no. of motor poles
set up feedback correctly
reduce Kp (speed controller)
replace feedback cable
join AGND to CNC-GND
increase I or I (keep within motor lim-
rms peak
its!)
shorten setpoint ramp +/-
reduce I /I
rms peak
increase Kp (speed controller)
use motor default value for Tn (speed con-
troller)
reduce ARLPF / ARHPF
reduce ARLP2
reduce Kp (speed controller)
use motor default value for Tn (speed con-
troller)
increase ARLPF / ARHPF
increase ARLP2
adjust setpoint-offset (analog I/O)
join AGND and CNC-GND
