Function modules

7.4 Extended brake control

speed controller is immediately enabled - the speed setpoint is enabled after the brake opening time (p1216). When the master switch is in the zero position, the speed setpoint is inhibited - the drive is ramp-down using the ramp function generator. The brake closes once the standstill limit (p1226) has been fallen below. After the brake closing time (p1217), the speed controller is inhibited (the motor is no longer generating any force). The extended brake control is used with the modifications described below.
