Trial Operation Of Servomotor With Brakes - YASKAWA SGDV User Manual

Step
Adjust the servo gain and improve the servomotor response characteristics, if neces-
sary.
7
Note: The servomotor will not be broken in completely during the trial operation.
Therefore, let the system run for a sufficient amount of additional time to
ensure that it is properly broken in.
Write the parameters set for maintenance in 10.4 Parameter Recording Table.
Then the trial operation with the servomotor connected to the machine is completed.

Note: If the digital operator is used, parameters can be saved. SigmaWin+, which is
a tool for supporting the servo drive, can then manage the saved parameters
in files.

Trial Operation of Servomotor with Brakes

Observe the following precautions when performing a trial operation of a servomotor with a brake.
• When checking the brake operation, take advance measures to prevent vibration due to gravity acting on the
machine or external forces.
• Check the operation of the servomotor disconnected from the machine and then check the operation with a
holding brake. If no problems occur, connect the servomotor to the machine and perform a trial operation.
Use the brake signal (/BK) from the SERVOPACK to control the brake.
For wiring on a servomotor with brakes and setting parameters, refer to 5.2.4 Holding Brakes.
Operation
Failures caused by incorrect wiring or wrong voltage application in the brake circuit may
damage the equipment or cause an accident resulting in death or injury. Follow the pro-
cedures and instructions for wiring and trial operation precisely as described in this man-
ual.
