Description
A 24V holding brake in the servo motor is controlled directly by the 17S drive
through software-selectable BRAKE parameter settings. The time and functional
relationships between the ENABLE signal, speed setpoint, speed and braking force
are shown in the following diagram.
through software-selectable BRAKE parameter settings. The time and functional
relationships between the ENABLE signal, speed setpoint, speed and braking force
are shown in the following diagram.
During the fixed ENABLE delay time of 100 ms, the speed setpoint of the drive is
internally driven down a 10 ms ramp to 0V. The 3 % region of actual speed is
scaled to V

Note: The set and release times of the holding brake vary with the servo motor and
thus must be considered when setting parameters.
