Test without a Motor
A test without a motor is used to check the operation of the host controller and peripheral
devices by simulating the operation of the Servomotor in the SERVOPACK, i.e., without actually
operating a Servomotor. This test allows you to check wiring, debug the system, and verify
parameters to shorten the time required for setup work and to prevent damage to the machine
that may result from possible malfunctions. The operation of the motor can be checked with
this test regardless of whether the motor is actually connected or not.
Use Pn00C = n.
X to enable or disable the test without a motor.
Motor Information and Encoder Information
The motor and encoder information is used during tests without a motor. The source of the
information depends on the device connection status.

Rotary Servomotor
If you use fully-closed loop control, the external encoder information is also used.
