Wiring Description For Cn5; Electromagnetic Brake Wiring - INVT DA180-S2R8SG0 Operation Manual

DA180 series basic AC servo drive

4.5.6 Electromagnetic brake wiring

If the servo motor is used to drive the vertical shaft, the electromagnetic brake can be used to prevent
against the falling of heavy objects or keep the falling speed when the servo drive is out of power. See
the following wiring diagram for the electromagnetic brake.
Drive side

You must provide independent 24V power for the electromagnetic brake, which cannot use the
signal-control power.

The electromagnetic brake is used for holding but not for common stop.

Though the electromagnetic brake can prevent the falling of heavy objects or keep the falling
speed, you must install an external brake device.
