D-16 Motion Mate™ DSM314 for Series 90™-30 PLCs User's Manual – January 2001 GFK-1742A

System Troubleshooting Hints (Analog Mode)
1. The DSM314 requires PLC firmware release 10.0 or greater and VersaPro software release
1.10 or greater.
2. If the Drive Ready input is enabled in the module configuration, the input must be connected
to 0v within 1 second after the Drive Enable relay turns on or the Motion Mate DSM314 will
not operate. Incorrect Drive Ready configuration or wiring will cause Error Code C0h to be
reported in the
Axis Error Code
%AI data.
3. The ENABLE DRIVE %Q control bit must be set continuously to
1
or no motion other than
Jog moves will be allowed. If no STOP errors (see Appendix A for error codes) have
occurred, the DRIVE ENABLED %I status bit will mirror the state of the ENABLE DRIVE
%Q bit. A STOP error will turn off the DRIVE ENABLED output bit even though ENABLE
DRIVE input bit is still a
1
. The error condition must be corrected and the CLEAR ERROR
%Q control bit turned on for one PLC sweep to re-enable the drive.
4. If the ERROR %I status bit is
1
and the AXIS ENABLED and DRIVE ENABLED %I status
bits are
0
, then a STOP error has occurred (Status LED flashing fast). In this state, the
DSM314 will not respond to any commands other than the CLEAR ERROR %Q control bit.
5. The CLEAR ERROR %Q control bit uses one-shot action. Each time an error is generated,
the bit must be set to
0
then set to
1
for at least one PLC sweep to clear the error.
6. The
CFG OK
LED must be ON or the DSM314 will not respond to PLC commands. If the
LED is OFF then a valid DSM314 configuration has not been received from the PLC, or there
may be a recognized configuration error. Check the %AI error code words for Dxxx errors,
which are documented in the “System Error Codes” section of Appendix A. Also check the
PLC fault tables for reported configuration errors.
7. PLC logic should not send the following %Q bit commands to the DSM314 on the first PLC
sweep:
Find Home, Execute Motion Program, Execute Local Logic
. If these commands are
sent on the first PLC sweep, an error will be reported and the action will not be performed.
8. PLC logic should not send the following %AQ commands to the DSM314 on the first PLC
sweep:
Move at Velocity, Move Command
. If these commands are sent on the first PLC
sweep, an error will be reported and the action will not be performed.
