Chapter 12 Inverter Function
•
Depending on the setting for [bb-25] Allowable
instantaneous power failure time and the number
of retries, the inverter's behavior varies.
•
When "0" is specified for the number of retries
(Error occurs)
Power recovery within [bb-25] Allowable
instantaneous power failure time
⇒
An error occurs.
Power recovery after [bb-25] Allowable
instantaneous power failure time has elapsed
⇒
An error does not occur. The same operation as
when the power is turned on.
•
Examples of supplying the power to R0 and T0
from P and N
•
[IP] signals start to be detected after 3-phase
power source has been input to main power
supply terminals R, S, and T.
•
If direct current is supplied between P and N, [IP]
signals will not be output.
•
When other than "0" is specified for the number of
retries (Retry enabled)
Power recovery within [bb-25] Allowable
instantaneous power failure time
⇒
Retry operation
Power recovery after [bb-25] Allowable
instantaneous power failure time has elapsed
⇒
An error occurs.
