2.16 Operation selection at power failure and
instantaneous power failure
2.16.1 Automatic restart after instantaneous power failure/flying start
[Pr. 30, 57, 58, 96, 162, 163*, 164*, 165, 298*, 299, 611]
(common)
When instantaneous power failure protection (E.IPF) and
undervoltage protection (E.UVT) are activated, the inverter
output is shut off. (Refer to page 111 for E.IPF and E.UVT)
When automatic restart after instantaneous power failure
operation is set with the following conditions, the motor can be
restarted if power is restored after an instantaneous power
failure or undervoltage. (E.IPF and E.UVT are not activated.)
• when electronic bypass operation is switched to inverter
operation
• when power comes back ON after an instantaneous
power failure
• when motor is coasting at start
Automatic restart after instantaneous power failure function is
invalid when load torque high speed frequency control ([
Pr.
270
= 2, 3]) is set.
