2.6 Wiring of the Motor Brake
2.6.1 Wiring of the Motor Magnetic Brake
The magnetic brake of servo motors with a magnetic brake is controlled by the motor brake control connector (CN9 and
CN20) on the servo drive unit. The servo drive unit releases the brake when the motor is ON. (Servo ON means when
torque is generated in the motor.) When using safe brake control (SBC), refer to 3.3. SBC (Safe Brake Control). Not that
for safe brake control the wiring and control sequence are different to the contents in this section.
(1) When using a motor brake for one axis
As shown in the illustration below, an external power supply circuit is controlled by the CN20 connector output.
Dynamic brake unit is controlled simultaneously for the servo drive unit with the capacity of MDS-E-V1-320W or
larger and MDS-EH-V1-160W or larger. Refer to "Dynamic brake unit wiring" for details.
CAUTION
1. CN20 connector and the brake can be connected directly because the servo drive unit contains the surge absorber.
2. The brakes cannot be released just by connecting motor brake terminal. 24VDC must be supplied.
3. For the 24V power supply used in the motor brake circuit, use the one separated from the 24V power supply for the
control circuit.
4. Only one axis can be controlled by the motor brake with CN20. The maximum brake tolerable current value of the CN20
is 1.7A.
