Trial Operation with the Servomotor Connected to the Machine
Perform the following steps for trial operation when the servomotor is connected to the machine.
The steps are specified on the condition that trial operation for servomotor without load has been completed in
each control method.
WARNING
Malfunctions that occur after the servomotor is connected to the machine may not only damage the
machine, but may also cause an accident resulting in death or injury.
Enable the overtravel signals (P-OT and N-OT) during trial operation with the servomotor
connected to the machine to provide a protective function.
Step Operation Reference
1
Turn ON the control power and main circuit power supplies and make the settings for
mechanical configuration related to protective function such as overtravel and brake.
Note: When a servomotor with brake is used, take advance measures to prevent
vibration due to gravity acting on the machine or external forces before
checking the brake operation. Check that both servomotor and brake opera-
tions are correct.

3
Connect the servomotor to the machine with coupling, etc., while the power is turned
OFF.

4
Turn ON the power to the machine (host controller) and then check that the SERVO-
PACK is servo OFF status. Check again that the protective function in step 1 operates
normally.
Note: For steps 4 to 8, take advance measures for emergency stop so that the servo-
motor can stop safely when an error occurs during operation.

tors after /S-ON Turned
OFF or Alarm Occur-
rence
5
Perform trial operation with the servomotor connected to the machine, following
each section in
4.3 Trial Operation for Servomotor without Load from Host Refer-
ence .
Check that the trial operation is completed with as the trial operation for servomotor
without load. Also check the settings for machine such as reference unit.

6
Check the settings of parameters for control method used set in step 2 again.
Check that the servomotor rotates matching the machine operating specifications.
