Check that relay contact capacity is 10 times or more than the rated
current. If less, use a multi-pole relay and use two or more relay
contacts serially. Reed life is extended.

Operation method
1. Control with NC program (M68, M69)
When the "M68" code is executed, BK+ to BK- is not energized
(brakes are applied), and when the "M69" code is executed, BK+ to
BK- is energized (brakes are released).
2. Control with brake release input (I/O connector, 18-pin)
If brake release is input while the brakes are applied, BK+ to BK- will
be energized (brakes are released).
If magnetic brakes are used frequently (frequently turned on and
off), use a solid-state relay (SSR) for the external contact.
Recommended model G3NA-D210B DC5-24 (OMRON)
Refer to the SSR instruction manual before using.

When passing a shaft through the hollow hole in the type with magnetic brakes, use a non-magnetic material (SUS303, etc.).
If magnetic material (S45C, etc.) is used, the shaft will be magnetized. This could cause iron powder to stick on the device or the
peripheral devices to be affected by the magnetic properties.
Note that around the magnetic brakes, iron powder, etc., could be attracted by the magnetic properties, or measuring instruments,
sensors and other devices could be affected.
1) Do not use magnetic brakes to brake or stop a rotating output shaft.
2) The driver will be damaged if the driver's BK+ and BK- and magnetic brakes are directly connected.
3) When connecting the following inductive load, such as a relay, to the external contact, set the coil rated voltage to 24 VDC and the rated
current to 100 mA or less, and provide measures against surge current.
4) When using magnetic brakes, supply 24 VDC power to external power input across pins 1, 2 and pins 3, 4 of the I/O connector (CN3).
