base block command is removed the inverter will accelerate from min. frequency.
- The inverter has no choices but can only normally start when using permanent magnetic motor.
■ Speed search based on current detection
(a) Speed search at starting
Figure 4.4.55 Speed search at starting
(b) Speed search in recovery period of momentary power failure
Figure 4.4.56 Speed search in recovery period of momentary power failure
Notes:
- If the minimum base block time (07-18) is longer than the momentary power failure time, the speed
search starts operation after the minimum base block time (07-18).
- If the minimum base block time (07-18) is too short, the speed search operation begins immediately
after power has been restored.
