2.8 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
ing". Our customer service can give you further assistance with problems.
Fault Possible causes
HMI message: wrong cable used
communication cable plugged into wrong position in
fault servo amplifier or PC
wrong PC interface selected
motor does not servo amplifier not enabled
rotate break in setpoint cable
motor phases swapped
brake not released
drive is mechanically blocked
no. of motor poles set incorrectly
feedback set up incorrectly
motor oscil- gain too high (speed controller)
lates shielding in feedback cable is broken
AGND not wired up
drive reports I or I
rms
following error
setpoint ramp is too long
motor over- I /I
rms
heating
drive too soft Kp (speed controller) too low
Tn (speed controller) too high
PID-T2 too high
T-Tacho too high
drive runs Kp (speed controller) too high
roughly Tn (speed controller) too low
PID-T2 too low
T-Tacho too low
axis drifts at offset not correctly adjusted for analog
setpoint = 0V setpoint provision
AGND not joined to the CNC-GND of
the controls
is set to low
peak
set too high

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 PID-T2
reduce T-Tacho
reduce Kp (speed controller)
use motor default value for Tn (speed con-
troller)
increase PID-T2
increase T-Tacho
adjust setpoint-offset (analog I/O)
join AGND and CNC-GND
