Motor Overspeed
18
OVERSPEED parameter in the
drive set to low for the applica-
tion
Using OMNI LINK (refer to Drive
Parameters section) set Over-
speed parameter to an accept-
able range for the application.
Motor commanded to run above
Overspeed setting
Reduce command from posi-
tion controller or change velocity
parameter in the position con-
troller.
Motor Phasing is incorrect
Check motor phasing.
Motor encoder phasing is incor-
rect
Check encoder phasing.
Excess Following Error
19
Software position error limit was
exceeded
Increase the feed forward gain
to 100%.
Increase the following error win-
dow (refer to OMNI LINK Drive
Parameters section).
Retune the drive to reduce the
following error.
Increase the slew limit window
(refer to OMNI LINK Drive
Parameters).
Motor Encoder State Error
20
Motor encoder encountered an
illegal transition
Replace the motor/encoder
Use shielded cables with
twisted pair wires.
Route the feedback away from
potential noise sources.
Check the system grounds.
Bad encoder
Replace motor/encoder.
Auxiliary Encoder state error
21
Auxiliary encoder encountered
an illegal transition
Use shielded cables with
twisted pair wires.
Route the encoder cable away
from potential noise sources.
Bad encoder - replace encoder
Check the ground connections
Motor Thermal Protection Fault
22
Internal filter protecting the
motor from overheating has
tripped.
Reduce acceleration rates
Reduce duty cycle (ON/OFF) of
commanded motion.
Increase time permitted for
motion.
User larger drive and motor.
IPM Thermal Protection Fault
23
Internal filter protecting the IPM
at slow speed has tripped.
Reduce acceleration rates
Reduce duty cycle (ON/OFF) of
commanded motion.
Increase time permitted for
motion.
User larger drive and motor.
Excess Velocity Error
24
Velocity error exceeded allow-
able range.
Increase time or size of allow-
able error.Reduce acceleration.
Commutation Angle Error
25
Encoder index location is incon-
sistent.
Replace encoder.
Check encoder and motor
power wiring.
