1.8 Troubleshooting the AKD

Drive problems occur for a variety of reasons, depending on the conditions in your install-
ation. The causes of faults in multi-axis systems can be especially complex. If you cannot
resolve a fault or other issue using the troubleshooting guidance presented below, customer
support can give you further assistance.
The most common faults are listed in Chapter "Fault and Warning Messages" (➜ # 193).
More details on the removal of faults can be found in the WorkBench online help.

wrong cable used, cable plugged
into wrong position on drive or PC
wrong PC interface selected
HW Enable not wired
HW or SW Enable not set
drive not enabled
software enable not set
break in setpoint cable
motor phases swapped
brake not released
drive is mechanically blocked
motor pole no. set incorrectly
feedback set up incorrectly
gain is too high (speed controller)
feedback cable shielding broken
AGND not wired up
Irms or Ipeak set too low
current or velocity limits apply
accel/decel ramp is too long
motor operating above its rating
motor current settings incorrect
Kp (speed controller) too low
Ki (speed controller) too low
filters set too high

MSI installer issue.
Harddisk space not sufficient
Remedy
plug cable into the correct sockets on the
drive and PC
select correct interface
connect HW Enable (X8 pin 4)
Apply 24V to HW Enable and select SW
Enable in WorkBench / Fieldbus
apply ENABLE signal
set software enable
check setpoint cable
correct motor phase sequence
check brake control
check mechanism
set motor pole no.
set up feedback correctly
reduce VL.KP (speed controller)
replace feedback cable
join AGND to CNC-GND
verify motor/drive sizing
verify that IL.LIMITN/P,VL.LIMITN/P are
not limiting the drive
reduce DRV.ACC/DRV.DEC
verify motor/drive sizing
verify motor continuous and peak current
values are set correctly
increase VL.KP (speed controller)
increase VL.KI (speed controller)
refer to documentation regarding reducing
filtering (VL.AR*)
reduce VL.KP (speed controller)
reduce VL.KI (speed controller)
refer to documentation regarding increas-
ing filtering (VL.AR*)
Cancel the installation. Relaunch the
installer (you may need to try several
times, the problem is random).
Make sure that you have enough disk
space on your hard disk (~500MB to allow
Windows .NET update if necessary), if
not make some space.
