Remedy:

  • Hardware fault – Contact the supplier of the drive.


221
Hardware trip has occurred during last power down

Cause:

The Stored HF trip indicates that a hardware trip (HF01 –HF19) has occurred and the drive has been power cycled. The sub-trip number identifies the HF trip i.e. stored HF.17.



Remedy:

  • Enter 1299 in Pr mm.000 and press reset to clear the trip.


227
RAM allocation error

Cause:

An option module, derivative image or user program image has requested more parameter RAM than is allowed. The sub-trip is calculated as (parameter size) + (parameter type) + sub-array number.



Remedy:

  • Check option modules and user program requirements.


218
Internal thermistor has failed

Cause:

The Temp Feedback trip indicates that an internal thermistor has failed. The thermistor location can be identified by the sub-trip number:




SourceSub-trip (xx y zz)Location
Control board00 00 01/02/03Control board thermistors / IO board
Power systemPower Mod Num / 0 / 0Power system communication feedback




Remedy:

  • Hardware fault – Contact the supplier of the drive.


10
Brake resistor over temperature

Cause:

The Th Brake Res is initiated if hardware based braking resistor thermal monitoring is connected and the resistor overheats.



Remedy:

  • Check brake resistor wiring.

  • Check braking resistor value is greater than or equal to the minimum resistance value.

  • Check braking resistor insulation.

  • If braking resistor is not used, disable trip via Action On Trip Detection (10.037).


25
Motor thermistor short circuit

Cause:

A temperature sensor connected to an analogue input or terminal 15 has a low impedance (i.e. < 50 Ω).

Sub-trip 3: Analog Input 3 Mode.

Sub-trip 4: P1 Thermistor Short Circuit Detect.



Remedy:

  • Check thermistor continuity.

  • Replace motor / motor thermistor.


24
Motor thermistor over-temperature

Cause:

The motor thermistor connected to terminal 8 (analog input 3) or terminal 15 (encoder) has indicated a motor over temperature.



Remedy:

  • Check motor temperature.

  • Check threshold level (07.048).

  • Check thermistor continuity.


110

Cause:

The power system has generated a trip but did not identify it. The cause is unknown.



Remedy:

  • Hardware fault – return the drive to the supplier.


91
User 24 V supply is not present on control terminals (1,2)

Cause:

User Supply Select is set to 1 or Low Under Voltage Threshold Select is set to 1, but no user 24 V supply is detected.



Remedy:

  • Ensure the user 24 V supply is present on control terminals 1 (0V) and 2 (24 V).


249
On board user program error

Cause:

An error has been detected in the onboard user program image. Common sub-trips:

1: Divide by zero

2: Undefined trip

3-7: Parameter access/write errors

30-33: Image CRC/RAM/OS errors

40: Timed task suspended

52-53: Menu table CRC/Changed

61-74: Option module slot conflicts

80-81: Image compatibility errors



Remedy:

  • Check the user program code and compilation settings.

  • Verify option module placement if sub-trips 61-74 occur.

  • Save parameters if sub-trip 53 occurs.


96
Trip generated by an onboard user program

Cause:

This trip can be initiated from within an onboard user program using a function call which defines the sub-trip number.



Remedy:

  • Check the user program.


36
User Save error / not completed

Cause:

An error has been detected in the user save parameters saved in non-volatile memory. Example: Power removed during save.



Remedy:

  • Perform a user save in Pr mm.000 to ensure that the trip doesn’t occur the next time the drive is powered up.

  • Ensure that the drive has enough time to complete the save before removing the power to the drive.


41 – 89
112 – 159
User generated trip

Cause:

These trips are not generated by the drive and are to be used by the user to trip the drive through an application program.



Remedy:

  • Check the user program.


40
Motor Rated Current or Speed not recognized (Dyneo LSRPM)

Cause:

The motor rated current or motor rated speed was not recognized as being a valid value for a Dyneo LSRPM motor.



Remedy:

  • Check the Rated Speed (Pr 00.045) and Rated Current (Pr 00.046).

  • Correct the values and perform an autotune again.

  • If using any other motor, set Pr 29.200 = 0 to disable the Dyneo LSRPM quick setup system.


30
Control word watchdog has timed out

Cause:

The control word has been enabled and has timed out. Once Pr 06.042 bit 14 is changed from 0 to 1, this must be repeated every 1s or a Watchdog trip occurs.



Remedy:

  • Ensure the watchdog bit is updated frequently.

  • Disable watchdog if not required (reset trip to re-enable).


HF01 – HF20
Internal / Hardware trips

Cause: Internal faults that do not have trip numbers. The main drive processor has detected an irrecoverable error.


Remedy:

  • Cycle power to the drive.

  • If the trip is non-permanent, it may reset.

  • If drive trips on “Stored HF” after power cycle, enter 1299 in mm.000 to clear the Stored HF trip.
