Note 1. When setting up an electromagnetic brake at customer's side, make up a sequence which will operate the
electromagnetic brake as follow using MBR (Electromagnetic brake interlock).
ON: Electromagnetic brake is not activated.
OFF: Electromagnetic brake is activated.
2. Give a position command after the external electromagnetic brake is released.
3. This is in position control mode.
4. In [Pr. PC02 Electromagnetic brake sequence output], set a delay time (Tb) from MBR (Electromagnetic brake
interlock) off to base circuit shut-off at a servo-off.
5. The base circuit remains ready-on status at servo-off. When the status is ready-off, the base circuit and the
servo-on command turn off at the same time. (Tb = 0)
