(2) 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.) It also contains duplex contacts for motor magnetic brake control to support
the safe brake control (SBC).
[1] Motor brake control connector (CN20) output circuit (When using the brake of L 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.
[2] Motor brake control connector (CN9) output circuit (When using the brake of M axis)
As shown in the illustration below, the brake control is enabled by using DO output of CN9 for an external
power supply circuit.
CAUTION
1. For SBC, the brake control of the CN20 connector is dedicated to the L axis and the brake control of the CN9 connector
is dedicated to the M axis.
2. The maximum brake tolerable current value of CN20 is 1.7A.
3. The brakes cannot be released just by connecting motor brake terminal. 24VDC must be supplied.
4. For the 24V power supply used in the motor brake circuit, use the one separated from the 24V power supply for the
control circuit.
