MAINTENANCE AND TROUBLESHOOTING
44
Motor Ground
Fault Ground fault has oc-
curred.
Make sure motor ground con-
nections are correct.
Replace defective motor ground
wires.
Check for internal motor winding
short circuits.
45
Drive AC Input
Over Voltage Fault Incoming AC voltage is
too high. Verify input VAC is within specif-
icaitons.
46
Overtravel Plus
Fault
Overtravel Plus Fault in-
put is off and Drive Ignore
Plus Travel Limit is off.
Overtravel Plus Fault status can
be monitored using READ_SV
variable 68 AND (16#400 0000).
Fault input write a 0 to
WRITE_SV variable 86. Use
DRSETFLT to reset fault indica-
tions. To override the Overtravel
Plus Fault input write a 1 to
WRITE_SV variable 86, Ignore
Plus Travel Limit. To reactivate
checking of the Overtravel Plus
input write a 1 to WRITE_SV
variable 86, Ignore Plus Travel
Limit. To reactivate checking of
the Overtravel Plus Fault input
write a 0 to WRITE_SV variable
86.
47
Overtravel Minus
Fault
This fault is set when the
Overtravel Minus Fault in-
put is off and Drive Ignore
Minus Travel Limit is off.
Overtravel Minus Fault status
can be monitored using
READ_SV variable 68 AND
(16#800 0000). Use DRSETFLT
to reset fault indications. To
override the Overtravel Minus
Fault input write a 1 to
WRITE_SV variable 87, Ignore
Minus Travel Limit. To reactivate
checking of the Overtravel Minus
Fault input write a 0 to
WRITE_SV variable 87.
51
Digital Link
Communication
Error
This fault is set when two
consecutive corrupt Digi-
tal Link messages are de-
tected or no Digital Link
messages are received
within 250 microseconds.
Digital Link Communication Er-
ror status can be monitored us-
ing READ_SV variable 68 AND
(16#1000 0000). This fault re-
quires that the user servo setup
function and DSTRTSRV be ex-
ecuted prior to executing
DRSETFLT to reset the fault in-
dication.
52
Invalid Switch
Setting Fault
This fault is set when the
drive address switch set-
ting is set to 0 or greater
than 64 or its setting is
changed while the Digital
Link is operating in cyclic
communications mode.
Invalid Switch Setting Fault sta-
tus can be monitored using
READ_SV variable 68 AND
(16#2000 0000). Use DRSET-
FLT to reset fault indications.
Note: Digital Link initialization
must be performed before this
fault can be reset.
