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.
