3-5-8 Brake Interlock (For Motors with Brakes)
H
Magnetic Brakes
The magnetic brakes for Servomotors with brakes are specialized holding brakes with non-magnetized
operation. Therefore set the parameters so that the brake power supply is turned off after the Servomo-
tor stops. If the brake is applied while the Servomotor is operating, the brake will suffer abnormal wear or
even damage, and will quickly become defective.
For wiring methods, refer to
2-2-5 Peripheral Device Connection Examples.
