Test Without Motor Function
The test without a motor is used to check the operation of the host controller and peripheral devices by simu-
lating the operation of the servomotor in the SERVOPACK, i.e., without actually operating a servomotor. This
function enables you to check wiring, verify the system while debugging, and verify parameters, thus shorten-
ing the time required for setup work and preventing damage to the machine that may result from possible mal-
functions. The operation of the motor can be checked during performing this function regardless of whether
the motor is actually connected or not.
Use Pn00C.0 to enable or disable the test without a motor.
4.3.1
Motor Information
The motor information that is used for a test without a motor is given below.
(1) When Motor is Connected
If a motor is connected, the information from the connected motor is used for the motor and encoder scale
information. The set values of Pn00C.1 and Pn00C.2 are not used.
(2) When Motor is Not Connected
The information for the virtual motor that is stored in the SERVOPACK is used. The set values of Pn00C.1
and Pn00C.2 are used for the encoder information.
Encoder Resolution
The encoder information for the motor is set in Pn00C.1. The setting of Pn00C.1 is not used for an external
encoder with fully-closed loop control.
