3.4.2 Time response of activation of STO in operation with restart
The figure below shows the time response from switching off the control voltage at STO-A/B and the
process required to restart the device. The times can be found in the table below. Notes:
–
The holding brake is controlled via the motor controller, not safety-related.
–
The coasting of the motor is shown, independent of activation/deactivation of the brake.
–
The setpoint value is only enabled when the holding brake delay T_BRAKE_V has expired.
