Chapter 3 Wiring of Servo System IS620P User Manual

The description of brake output time sequence is as follows:
When the servo is ON, wait for the operation delay time of the brake (as set in H02-09) before
sending commands to the servo drive. Otherwise, the servo drive does not respond.
When the servo is OFF, the brake signal is immediately sent out. The servo motor is still ON
within the delay time as set in H02-10, to prevent heavy objects from falling due to gravity.
