Troubleshooting 4-5
5 Opt Port 0 Loss A fault on port 0 of the Hi-Resolution Encoder Feedback Option
Card, MDI Option Card, or Resolver Feedback Option Card has
occurred.
Parameter 260 [Hi-Res0 Status] displays the fault status for port 0 of
the Hi-Resolution Encoder Feedback Option Card.
Parameter 267 [Resolver0 Status] displays the fault status for port 0
of the Resolver Feedback Option Card.
6 Opt Port 1 Loss The Linear sensor portion of the MDI feedback option card has
detected a fault condition.
Parameter 286 [Linear1 Status] displays the fault status for linear
portion of the MDI feedback Option Card.
9 Slink Comm Fail A SynchLink communication fault has occurred.
Parameter 1229 [SL Error Status] displays SynchLink errors.
10 Drive Power Loss DC Bus voltage has fallen below the minimum value
• Parameter 306 [DC Bus Voltage] displays bus voltage
• Parameter 330 [Fault TP Data] displays the minimum value when
parameter 329 [Fault TP Sel] is set to five
The drive must first complete precharge before this check is made
11 Motor Oload Trip A motor overload trip has occurred.
Parameter 308 [Output Current] is squared, scaled and integrated
over time. When this integrated value exceeds 1.0, this Exception
Event occurs.
The integrator's output can be viewed in Parameter 330 [Fault TP
Data] when parameter 329 [Fault TP Sel] is set to 13 “Mtr OL Outpt”.
The overload integration rate is affected by parameters 336 [Service
Factor], 337 [Mtr I2T Curr Min], 338 [Mtr I2T Spd Min] and 339 [Mtr
I2T Calibrat].
Reduce mechanical load
12 Motor Oload Pend A motor overload is pending.
Parameter 308 [Output Current] is squared, scaled and integrated
over time. When this integrated value exceeds 0.5, this Exception
Event occurs.
The integrator's output can be viewed in Parameter 330 [Fault TP
Data] when parameter 329 [Fault TP Sel] is set to 13 “Mtr OL Outpt”.
The overload integration rate is affected by parameters 336 [Service
Factor], 337 [Mtr I2T Curr Min], 338 [Mtr I2T Spd Min] and 339 [Mtr
I2T Calibrat].
Reduce mechanical load
13 Motor Stalled The motor has stalled. These three conditions have occurred at the
same time for the amount of time specified in parameter 373 [Motor
Stall Time]:
• Drive is not stopped (parameter 150 [Logic State Mach] not equal
to zero)
• Drive is on limit (parameter 304 [Limit Status] not equal to zero)
• Drive is at zero speed (parameter 155 [Logic Status], bit 13 [At
Zero Spd] is set).
1. Increase torque limit
2. Reduce mechanical load
14 Inv Otemp Pend Parameter 313 [Heatsink Temp] is within 10
° C of maximum.
View the maximum heat sink temperature in parameter 348 [Drive
OL TP Data] when parameter 347 [Drive OL TP Se] is set to 30
[fMaxHsDegc].
15 Inv Otemp Trip Parameter 313 [Heatsink Temp] is above the maximum limit or
temperature sensor has failed (shorted or open.
See parameter 346 [Drive OL Status], bit 0 [NTC Shorted] and bit 1
[NTC Open].
