(1) Servo-on (RYn0) command (from controller) ON/OFF
Tb [ms] after the servo-on (RYn0) is switched off, the servo lock is released and the servo motor coasts. If
the electromagnetic brake is made valid in the servo lock status, the brake life may be shorter. Therefore,
when using the electromagnetic brake in a vertical lift application or the like, set Tb to about the same as
the electromagnetic brake operation delay time to prevent a drop.

2. Electromagnetic brake is released after delaying for the release delay time of electromagnetic brake and operation time of
external circuit relay. For the release delay time of electromagnetic brake, refer to Servo Motor Instruction Manual (Vol.2).
3. After the electromagnetic brake is released, turn ON the RYn1 or RYn2.
