Output voltage limitter
When min. baseblock
time is longer than mo-
mentary power loss time.
To ensure that a fault such as OC does not occur during speed
search operation, V/f must be reduced during speed search opera-
tion, as compared with that during normal operation. Set V/f during
speed search as follows by the set value of No. 56:
V/f during speed search = V/f at normal operation x No. 56
No. 1
The Inverter may malfunction if V/f is extremely large. To limit the
output voltage in order to prevent the Inverter from malfunctioning,
use the output voltage limiter function. In usual operation, howev-
er, it is not necessary to use this function.
No. 1 = 0xxx
