4-2 No-load Servo Motor with Supervisory Controller Trial 
Run 
This stage of the Trial Run can determine whether or not the Control Signal Wiring between the 
Servo Driver and the Supervisory Controller is correct and whether or not the control signal electric 
potential is correct. After completing this stage of the Trial Run, the Servo Motor can be connected to 
the mechanism. 
 
A. Start Servo Motor: 
Please refer to the following to conduct wiring 
Speed Control (
Cn001=1
)   Position Control (
Cn001=2
) 
 
 
 
a.  Confirm that there is no command signal input: 
In the speed control mode, please input 0V to the speed analog input contact. 
In the position control mode, please short the external pulse command contact, short Pulse 
and /Pulse, short Sign and /Sign. 
 
b.  Start the Servo ON Signal: 
Connect the servo start contact 
(SON)
 to the low electric potential and start the servo motor 
to observe whether or not there is any error signal generated. If there is still an error alarm, 
the user needs to resolve the alarm conditions in accordance with “9-2 Countermeasures to 
Clear Error”.
