5 OPERATION
This section provides precautions at test run and operation. For instructions on test run and
operation, refer to the “
Σ-II series SGM H/SGDH User’s Manual” (SIEPS80000005).
5.1 Precautions at Test Run
„ Conducting Test Run for Servomotor without Load
When servomotor is operated without load, set the load inertia ratio (parameter Pn103) to 0.
(Factory setting is 0.)
When servomotor is rotated without load, if the value has been set to other than 0, the servo-
motor may oscillate.
To avoid this, make sure to set the load inertia ratio to 0 and then servo on.
„ Conducting Test Run with Servomotor Connected to Machine
SERVOPACK initial parameters setting is performed assuming normal operation conditions.
Before test run, set up parameters suitable for the machine.
Failure to set up the parameters initial setting may result in machine overrun or failure.
As for the setting procedures and methods, refer to the “ Σ-II Series SGM H/SGDH User’s
Manual” (SIEPS80000005).
„ Check Item during Test Run
The following items should be checked during test run.
• Unusual vibration
• Abnormal noise
• Excessive temperature rise
• To avoid inadvertent accidents, run the servomotor only in test run (without load).
Failure to observe this caution may result in personal injury.
• Before starting operation with a load connected, set up parameters suitable for the machine.
Starting operation without setting up parameters may result in machine overrun or failure.
• Before starting operation with a connected load, make sure emergency-stop procedures are in
place.
Failure to observe this caution may result in personal injury.
