• Always connect a surge absorber.
• After the surge absorber is connected, check the total time the brake is applied for the
system. Depending on the surge absorber, the total time the brake is applied can be
changed.
• Configure the relay circuit to apply the holding brake by the emergency stop.
• Always separate the brake power supply from other power supplies, such as the con-
trol or I/O signal (CN1) power supplies. If the power supply is shared, the I/O signals
might malfunction.
