Operating Functions
5-6 Brake Interlock
You can set the Brake Interlock Signal (BKIR) timing to turn ON and OFF the electromagnetic brake.
Parameters Requiring Setting
Operation
RUN Command Timing (When Servomotor Is Stopped)
*1. The time from turning ON the brake power supply to releasing the brake is 200 ms max. Provide
a pulse command after the brake has been released, taking into account this delay.
*2. The time from turning OFF the brake power supply to the brake engaging is 100 ms max. If using
the Servomotor on a vertical axis, take this delay into account and set the B
rake Timing when
Stopped (Pn6A) longer
so that the Servomotor power is turned OFF after the brake has been
held.
The electromagnetic brake of a Servomotor with a brake is a non-
excitation brake designed for holding. Set the parameter to first stop the
Servomotor, and then turn OFF the power supply to the brake.
If the brake is applied while the Servomotor is rotating, the brake disk may
become damaged due to friction, leading to the Servomotor malfunction.
