Function description:
The completion of a 'waiting time' is one condition for the pulse enable after an overvoltage in the DC bus (OU message). The waiting time is started by the pulse inhibit. The time elapsing until another pulse is inhibited depends on the motor. The waiting times result from the double motor time constant TM which is calculated as follows:
C0912 [ms] = LH/RR = C0092 [mH] / C0082 [Ω] * 2
The time of a pulse inhibit after occurrence of an OU message can be indicated and parameterised via code C0912 [ms]. The value under code C0912 can be changed in 1 ms steps up to the max. value of 9999 ms. The minimum value results from the following device assignment:
- 9335 (400/500 V): 1000 ms
- 9336 (400/500 V): 1250 ms
- 9337 (400/500 V): 1500 ms
- 9338 (400/500 V): 1750 ms
- 9381 (400/500 V): 2000 ms
- 9382 and 9383 (400/500 V): 2250 ms
Application:
Pulse inhibit after occurrence of an overvoltage in the DC bus.
