Note
• Applying a voltage over the
specification will increase the
temperature rise in the
electromagnetic brake and may
damage the motor.
Conversely, insufficient voltage
may prevent the brake from
releasing.
• Be sure to connect the varistor
(non-polarized) to protect the
switch contacts and prevent
noise.
• The lead wires for the
electromagnetic brake are
polarized. Connecting the lead
wires in reversed polarity will not
properly operate the
electromagnetic brake.

Connecting power supply for the electromagnetic brake
Provide a DC power-supply cable of 24 VDC±5% at 0.3 A or more.
Use a shielded cable of AWG24 (0.2 mm
brake to the DC power supply, keeping the length as short as possible.
Using an electromagnetic-brake-type extension cable (sold separately)
Model: CC01AIPM, CC02AIPM, CC03AIPM, CC05AIPM, CC07AIPM, CC10AIPM,
CC15AIPM, CC20AIPM
Use two (orange/black and gray) lead wires [60 mm (2.36 in.)] from the driver's connector side.
1
. Connect the orange/black lead wire to the +24 V terminal of the DC power supply.
2
. Connect the gray lead wire to the GND terminal of the DC power supply.
3
. Connect the varistor in parallel across the +24 V and GND terminals of the DC power supply.
The varistor is non-polarized.
Using an electromagnetic-brake-type flexible cable (sold separately)
Model: CC01SARM2, CC02SARM2, CC03SARM2,
CC05SARM2, CC07SARM2, CC10SARM2
Use two (orange and gray) lead wires [60 mm (2.36 in.)] from the driver's connector side.
1.
Connect the orange lead wire to the +24 V terminal of the DC power supply.
2.
Connect the gray lead wire to the GND terminal of the DC power supply.
3.
Connect the varistor in parallel across the +24 V and GND terminals of the DC power supply.
The varistor is non-polarized.
