If you will use a holding brake, observe the following precautions during trial operation.
n Before you check the operation of the brake, implement measures to prevent the
machine from falling due to gravity and to prevent vibration from being caused by an
external force.
n First check the Servomotor operation and brake operation with the Servomotor
uncoupled from the machine. If no problems are found, connect the Servomotor to the
machine and perform trial operation again.
Control the operation of the brake with the /BK (Brake) signal output from the SERVO-
PACK.
Refer to the following sections for information on wiring and the related parameter set-
tings.
Ä
Chap. 5.5.4 ‘Wiring the SERVOPACK to the Holding Brake’ page 114
Ä
Chap. 6.12 ‘Holding Brake’ page 167
Failures caused by incorrect wiring or incorrect voltage application in the
brake circuit may cause the SERVOPACK to fail, damage the SERVO-
PACK, damage the equipment, or cause an accident resulting in death or
injury.
Observe the precautions and instructions for wiring and trial operation
precisely as described in this manual.
8.6.3 Preparations
Confirm the following items before you perform the trial operation procedure for both the
machine and Servomotor.
n Make sure that the procedure described in
Ä
Chap. 8.5 ‘Trial Operation with
PROFINET Communications’ page 272 has been completed.
n Make sure that the SERVOPACK is connected correctly to both the host controller
and the peripheral devices.
– Safety Function Wiring
If you are not using the safety function, leave the Safety Jumper Connector (pro-
vided as an accessory with the SERVOPACK) connected to CN8.
If you are using the safety function, remove the Safety Jumper Connector from
CN8 and connect the safety function device.
– Overtravel wiring
– Brake wiring
– Allocation of the /BK (Brake) signal to a pin on the I/O signal connector (CN1)
– Emergency stop circuit wiring
– Host controller wiring
8.6.4 Operating Procedure
1. Enable the overtravel signals.

2. Make the settings for the protective functions, such as the safety function, over-
travel, and the brake.
