(77CH)
Speed Search Induced Voltage
Level
There is normally no need to change this parameter from the default value.
Performs Speed Search when the motor induced voltage exceeds the set level. If changes are
necessary, try lowering this value in small increments. If set too low, then the drive will not
perform Speed Search.
Note: This parameter is not available with models CIMR-A4A0930 and 4A1200.
Default: 10%
Min: 0%
Max: 10%

Speed Search Selection when
Driving Instruction is Input in Uv
Activates or deactivates the speed search at start in accordance with whether or not a Run
command was issued during an undervoltage (Uv) if operation during a momentary power loss
(L2-01 = 1 or 2), the speed search at start (b3-01 = 1), and coasting to a stop (b1-03 = 1) are
enabled.
