Subfault: 16.12
Description: Motor data write sequence
Response: Output stage inhibit
Cause
Measure
Subindex 1 not written to zero before writing elec-
trical startup parameters (index 8357, 8360,
8394, 8420 or 8358, 8361, 8395, 8421).
Reset the error. Set parameters 8360/1 or 8361/1
to "0" before writing 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 frequency).
Subfault: 16.21
Description: Nominal slip negative
Response: Output stage inhibit
Cause
Measure
During startup using nameplate data, the calcu-
lated 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 calculate the number of pole pairs ac-
curately from nominal frequency and nominal
speed.
Enter the number of pole pairs.
Subfault: 16.23
Description: Plausibility check failed
Response: Output stage inhibit
Cause
Measure
During startup using nameplate data: The estim-
ated nominal power does not match the entered
nominal power.
Check entered nameplate data for plausibility.
