10.5 Troubleshooting the AKD
Drive problems occur for a variety of reasons, depending on the conditions in your installation. 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.
Eliminate errors and faults in compliance with work safety rules. Troubleshooting only by
qualified and trained staff.
More information about error messages, causes, remedy and clearing errors can be found in
the WorkBench online help and in

connect HW Enable (X8 pin 4)
Apply 24V to HW Enable and select SW
Enable in WorkBench / Fieldbus

brake not released
drive is mechanically blocked
motor pole no. set incorrectly
feedback set up incorrectly
apply ENABLE signal
set software enable
check setpoint cable
correct motor phase sequence
check brake control
check mechanics
set motor pole no.
set up feedback correctly
Motor oscillates
gain is too high (speed controller)
feedback cable shielding broken
AGND not wired up
reduce VL.KP (speed controller)
replace feedback cable
join AGND to CNC-GND
Drive reports
following error
Irms or Ipeak set too low
current or velocity limits apply
accel/decel ramp is too long
verify motor/drive sizing
verify that IL.LIMITN/P,VL.LIMITN/P are
not limiting the drive
reduce DRV.ACC/DRV.DEC
Motor overheating
motor operating above its rating
motor current settings incorrect
verify motor/drive sizing
verify motor continuous and peak current
values are set correctly
Drive too soft
Kp (speed controller) too low
Ki (speed controller) too low
filters set too high
increase VL.KP (speed controller)
increase VL.KI (speed controller)
refer to documentation regarding reducing fil-
tering (VL.AR*)
Drive runs roughly
Kp (speed controller) too high
Ki (speed controller) too high
filters set too low
reduce VL.KP (speed controller)
reduce VL.KI (speed controller)
refer to documentation regarding increasing
filtering (VL.AR*)
During installation,
the message “Please
wait while the
installer finishes
determining your disk
space requirements”
appears and never
disappears.
MSI installer issue.
Harddisk space not sufficient
Cancel the installation and relaunch the
