Subfault: 16.7
Description: PWM frequency not possible
Response: Output stage inhibit
Cause Measure
The specified PWM frequency is not allowed for this power out-
put stage.
Select different PWM frequency. Possible PWM frequencies;
see device configuration data.
Subfault: 16.8
Description: Temperature sensor motor 1
Response: Output stage inhibit
Cause Measure
Faulty startup of temperature sensor for motor 1. Perform startup again.
Subfault: 16.9
Description: Temperature sensor motor 2
Response: Output stage inhibit
Cause Measure
Faulty startup of temperature sensor for motor 2. Perform startup again.
Subfault: 16.10
Description: Actual position source not assigned
Response: Application stop + output stage inhibit
Cause Measure
The active control mode requires an encoder for position mode. Assign the actual position source in the encoder assignment of
the active drive train: 8565.3 or 8566.3.
If no encoder is installed, activate the FCBs only using "torque
control" or "speed control" mode.
Subfault: 16.11
Description: Motor data calculation error
Response: Output stage inhibit
Cause Measure
Motor startup is not possible because of inconsistent motor
data or wrong device configuration data.
Motor data and device configuration data are checked for
plausibility. Or contact the SEW‑EURODRIVE Service.
Subfault: 16.12
Description: Motor data write sequence
Response: Output stage inhibit
Cause Measure
Subindex 1 was not written to zero before writing the electrical
startup parameters 8357, 8360, 8394, 8420 or 8358, 8361,
8395, 8421.
Reset error. Set parameters 8360/1 or 8361/1 to 0 before writ-
ing additional parameters.
Subfault: 16.20
Description: Nominal speed too high or nominal frequency too low
Response: Output stage inhibit
Cause Measure
During startup using nameplate data: Nominal speed too high
or nominal frequency too low. The resulting number of pole
pairs is 0.
Enter plausible motor data (nominal speed and nominal fre-
quency).
Subfault: 16.21
Description: Nominal slip negative
Response: Output stage inhibit
Cause Measure
During startup using nameplate data, the calculated nominal
slip is negative: Nominal frequency too low or nominal speed
too high or number of pole pairs too high.
Enter plausible motor data (nominal frequency, nominal speed,
number of pole pairs).
Subfault: 16.22
Description: Specify the number of pole pairs
Response: Output stage inhibit
Cause Measure
During startup using nameplate data: It is not possible to calcu-
late the number of pole pairs accurately from nominal fre-
quency and nominal speed.
Enter the number of pole pairs.
