(2) When using motor brakes for 2 axes or 3 axes
When controlling multiple motor brakes with 2-axis or 3-axis drive units, the motor brakes must be connected in
parallel to the connector CN9 using the external 24V driving relay as shown in the illustration below.
< Caution in use of MDS-E/EH-V2/V3 >
It is required to input a servo OFF command to all axes in order to turn the brake ON with a motor brake control
output (CN20) of drive unit. Input the servo OFF command to an axis cannot turn the brake ON. Therefore, when
performing a control to fix the position with the motor brake by the servo OFF command during the motor stop for
PLC axis, use 1-axis drive unit.
During emergency stop, the servo OFF is applied to all axes at same time, so a brake control is not affected.
CAUTION
When using SBC (Safe Brake Control) function, the CN9 connector is dedicated to the M axis and the motor brakes cannot
be connected in parallel.
Refer to "3.3 SBC (Safe Brake Control)" for details.
