Fault 16 Startup

Response: Output stage inhibit

Cause

Measure

The motor has not been started up or not started up completely.

Perform complete motor startup.

Response: Output stage inhibit

Cause

Measure

The long delay of the encoder used prevents the calculation of the required filter coefficients.

Use an encoder with a shorter dead time.

Response: Output stage inhibit

Cause

Measure

Starting up thermal model not yet completed or its parameterization invalid.

Perform startup again.

Response: Output stage inhibit

Cause

Measure

Current limit smaller than magnetizing current of motor calculated by active control mode.

Increase the current limit.

Response: Output stage inhibit

Cause

Measure

When starting up a synchronous third-party motor, some control modes and drive functions are only permitted after motor parameter measurement.

Perform a motor parameter measurement using the FCB 25 drive function.

Wrong control mode selected for the motor.

Choose a suitable control mode.

Response: Output stage inhibit

Cause

Measure

The motor requires a higher PWM frequency than the inverter can provide.

Use an inverter with suitable PWM frequency.

The ELSM® control mode can only be used with an inverter that supports PWM frequencies of 2.5, 4 or 8 kHz.

Use an inverter with suitable PWM frequency.

The FCB 25 drive function can only be used with an inverter that supports PWM frequencies of 2.5, 4 or 8 kHz.

Use an inverter with suitable PWM frequency.

The FCB 18 drive function can only be used with an inverter that supports PWM frequencies of 2.5, 4 or 8 kHz.

Use an inverter with suitable PWM frequency option.

The set speed controller sampling cycle of 1 ms is not possible with the set PWM frequency.

– Set PWM frequency of 4, 8, or 16 kHz.

or

– Adjust the sampling cycle.

Response: Output stage inhibit

Cause

Measure

Error taking into operation the temperature sensor of motor 1.

Check the startup parameters.

Response: Output stage inhibit

Cause

Measure

Error taking into operation the temperature sensor of motor 2.

Check the startup parameters.

Response: Application stop + output stage inhibit

Cause

Measure

In the selected drive function, an encoder is required for position control that is used as the source for calculating the actual position.

– Assign an encoder for the position control in the drive train configuration.

– If no encoder is present, only use FCBs without positioning control.

Response: Output stage inhibit

Cause

Measure

Motor startup cannot be performed because of inconsistent motor data or wrong device configuration data.

– Check the startup.

– If the fault occurs repeatedly, contact SEW‑EURODRIVE Service.

Response: Output stage inhibit

Cause

Measure

Write sequence not adhered to before writing electrical startup parameters.

Perform startup again.

Response: Output stage inhibit

Cause

Measure

Several motor protection models are active in one of the thermal motor monitorings.

– Perform startup again.

– If the fault occurs repeatedly, contact SEW‑EURODRIVE Service.

Response: Output stage inhibit

Cause

Measure

No plausible value could be determined when calculating the number of pole pairs from the nominal speed and nominal frequency.

– Check the settings for nominal speed and nominal frequency.

– Perform startup again.

Response: Output stage inhibit

Cause

Measure

Negative slip determined at startup.

– Check the settings for nominal speed and nominal frequency.

– Perform startup again.

Response: Output stage inhibit

Cause

Measure

It is not possible to calculate the number of pole pairs accurately from nominal frequency and nominal speed.

Enter the number of pole pairs.

Response: Output stage inhibit

Cause

Measure

The estimated nominal power does not match the nominal power entered at startup.

– Check the entered data.

– Perform startup again.

Response: Application stop + output stage inhibit

Cause

Measure

For ELSM® control mode, the only permitted speed controller sampling cycles are 1 ms and 2 ms.

Set the sampling cycle to 1 ms or 2 ms.

The set speed controller sampling cycle of not equal to 2 ms is not possible with the set PWM frequency.

– Set the PWM frequency that matches the sampling cycle.

or

– Set sampling cycle to 2 ms (suitable for PWM frequency).

Response: Output stage inhibit

Cause

Measure

The user-defined power limits are too low for the configured standstill current.

– Increase user-defined current limit.

or

– Reduce standstill current.

Response: Output stage inhibit

Cause

Measure

One or all of the following parameters are not set correctly or are not plausible:

– Nominal voltage

– Nominal current

– Nominal speed

– Nominal torque

– Check the entered data.

– Perform startup again.

Response: Output stage inhibit

Cause

Measure

The following parameters are not set or are not plausible:

– Maximum current

– Maximum torque

– Check the entered data.

– Perform startup again.

Response: Warning

Cause

Measure

The EtherCAT®/SBusPLUS EEPROM is incorrectly configured.

Contact SEW‑EURODRIVE Service.

Response: Output stage inhibit

Cause

Measure

The startup data set on the replaceable memory module is not valid for the selected motor.

– Start up a different motor.

– Replace the memory module.

Response: Output stage inhibit

Cause

Measure

No startup data set found on the replaceable memory module for the selected motor.

– Start up a different motor.

– Replace the memory module.

Response: Output stage inhibit

Cause

Measure

No brake data available.

Check the startup.

Response: Output stage inhibit

Cause

Measure

The PID controller has been activated but the source of the actual value has not been defined yet.

Define the source of the actual value.

Response: Warning

Cause

Measure

No 3-wire control stop terminal parameterized.

Set stop terminal parameters.
