Description
Error Type
Possible Cause
C9
Stop Fast
Encoder CRC checksum
failure
Axis
The encoder communications circuit has
detected a CRC error. Check the encoder
cable grounding and the motor grounding
for possible error sources. Check for other
electrical noise sources in the area of the
motor and encoder cabling. Isolate these
sources from motor/encoder cabling if
possible. If error persists consult factory
CA
Stop Fast
Unsupported encoder, linear
or Type A
Axis
The motor encoder connected to the
module is not supported. Motor is either not
supported by the DSM module or has an
incorrect encoder attached to the motor.
Check motor label and verify motor is a
supported model. If problem persists
consult factory
CB
Stop Fast
Unsupported encoder, Type C
Axis
The motor encoder connected to the
module is not supported. Motor is either not
supported by the DSM module or has an
incorrect encoder attached to the motor.
Check motor label and verify motor is a
supported model. If problem persists
consult factory
CC
Normal Stop
Missed DZ pulse when DS
transitioned from 1 to 0
Axis
Position data may be incorrect. Power-cycle
motor and amplifier. If problem persists
consult factory.
DSP Alarms
D1
Stop Fast
Over current Detected
Axis
The Motor Control firmware detected an
over current condition. Possible sources for
this error include:
- Incorrect Motor Type selected in Hardware
configuration
- Machine back driving motor excessively
- Over Duty cycle conditions
D2
N/A
Not Used
D3
Stop Fast
Over Acceleration Detected
Axis
The Motor Control firmware detected an
acceleration value that exceeded allowed
values. This error is not encountered under
normal operating conditions. Possible error
causes include encoder failure, encoder
slippage, incorrect position reported from
encoder. If error is not explained by physical
hardware consult factory.
