4-2 Trial Operation for Servo motor without Load from 
Host Reference  
z  Check and ensure that all power connections to the drive and motor and control signal 
connection between the host controller and the drive are correct. Motor must be 
mechanically disconnected from the load. 
z  Following section describes the trial run when using a host controller such as a PLC. 
z  Two trial runs have been discussed. Speed control mode ( Section B) and Position control 
mode ( Section C). 
z  Section A shows the connections and SON signal (servo on) requirements for both trial 
runs. 
A.  Launching Servo motor  
  Example wiring diagram: 
Speed Control(Cn001=1)  Position Control(Cn001=2) 
a.  Disable Analog Input command terminals.  
Speed control mode: Link analog input terminal SIN to 0V terminal (AG).  
Position control mode: Link external pulse command terminals “Pulse” to ”/Pulse”  and “Sign” to  
“/Sign”.  
b.  Enable Servo ON Signal   
Connect SON terminal to IG 24  (0V) terminal (Digital Ground). 
On drive power up servo will be turned on. Now check for any Alarms. If any alarms then refer to 
Chapter 8-2 for how to reset the Alarms.  
 
y  To control the motor operating and stop, please input Torque/Speed/Position command after 
Servo ON. 
y  When input Torque/Speed/Position command, Please do not control the motor operating and 
stop by using servo on signal.
