1-4 Troubleshooting and Error Codes
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 [Motor OL Factor],
337 [Mtr I2T Curr Min], 338 [Mtr I2T
Spd Min] and 339 [Mtr I2T Calibrat].
• Reduce the mechanical load
• Enter the correct motor nameplate
full load amps in parameter 2
[Motor NP FLA]
• Configure with parameter 371 [Mtr
OL Trip Cnfg]
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 [Motor OL Factor],
337 [Mtr I2T Curr Min], 338 [Mtr I2T
Spd Min] and 339 [Mtr I2T Calibrat].
• Reduce the mechanical load
• Enter the correct motor nameplate
full load amps in parameter 2
[Motor NP FLA]
• Configure with parameter 372 [Mtr
OL Pend Cnfg]
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]:
1.) Drive is not stopped (parameter
150 [Logic State Mach] not equal to
zero)
2.) Drive is on limit (parameter 304
[Limit Status] not equal to zero)
3.) Drive is at zero speed (parameter
155 [Logic Status] / bit 13 “At Zero
Spd” is set).
• Increase torque limit
• Reduce mechanical load
• Configured with parameter 374
[Motor Stall Cnfg]
14 Inv OTemp Pend Parameter 313 [Heatsink Temp] is
within 10°C of the maximum value.
View the maximum heat sink
temperature in parameter 348 [Drive
OL TP Data] when parameter 347
[Drive OL TP Sel] is set to 30 -
“fMaxHsDegc”.
• Reduce the mechanical load
• Lower the ambient temperature
• Configured with parameter 375
[Inv OT Pend Cnfg]
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”.
• Reduce the mechanical load
• Lower the ambient temperature
• Verify that the cooling fan(s) and
fan inverter(s) are running and
functioning properly.
• Check the heatsink for blockage or
excessive dirt and clear/clean as
necessary.
• Check the air filters (if present) for
blockage and replace as
necessary.
