Chapter 12 Inverter Functions
Setting Items Required for the Brake Control 1 Function
*1) If [AF130] = 01, the forward rotation settings,
[AF131] to [AF137] are valid for both the forward
and reverse rotations.
*2) Set the time greater than the value of the
minimum speed [Hb130].
*3) Note that a low value for the setting may generate
sufficient torque when releasing the brake.
