Test Without Motor Function

The test without motor function is used to check the operation of the host and peripheral devices by simulating
the operation of the motor in the SERVOPACK, i.e., without actually operating the motor. This function
enables checking wiring and verifying the system and parameters when errors occur while debugging the sys-
tem, thus shortening the time required for setup work and preventing damage to the equipment that may result
from possible malfunctions. The operation of the motor can be checked during performing this function
regardless of whether the motor is actually connected or not.

4.6.1 Related Parameters

Absolute encoder is only for rotational servomotors. External encoders such as encoders for fully-closed loop control
are used as incremental encoders regardless of the setting of Pn00C.2.

4.6.2 Limitations

The following functions cannot be used during the test without motor.
• Regeneration and dynamic brake operation
• Brake output signal (The brake output signal can be checked with the I/O signal monitor function of the Sig-
maWin+.)
• Items marked with "X" in the utility function table on the next page.
If the encoder cable is disconnected and then connected again during the test without motor after having
started the test with the encoder cable connected, the utility functions that can be executed are limited to:
• Items marked with " " in the "Motor not connected" column in the utility function table on the next page.
