Parameter Description
Warning:
1. MC1 and MC2 must be mechanically interlocked; the running direction of the inverter
operation and the commercial power supply operation should be consistent.
2. Use the commercial power operation switchover function under the external operation mode.
3. STF/STR is effective when the CS signal is ON.
Here are some typical sequence diagrams for the switchover of the commercial power supply
frequency:
1. No action sequence for the automatic switchover sequence (P.249=99999).
2. With action sequence for the automatic switchover sequence (P.249
99999, P.250=99999).
3. With action sequence for the automatic switchover sequence series (P.249
99999, P.250 99999).
