Step 1: Trial Operation for Servomotor without Load
• Do not operate the servomotor while it is connected to the equipment.
To prevent accidents, initially perform step 1 where the trial operation is conducted under no-load conditions
(with all couplings and belts disconnected).
In step 1, make sure that the servomotor is wired properly as shown below. Incorrect
wiring is generally the reason why servomotors fail to operate properly during trial
operation.
•
Check main power supply circuit wiring.
•
Check servomotor wiring.
•
Check CN1 I/O signal wiring.
Make sure the host controller and other adjustments are completed as much as possi-
ble in step 1 (prior to connecting the servomotor to equipment).
Note Check the items on the following pages in the order given during the servomotor trial operation.
See 4.2.1 Servomotors with Brakes, if you are using a servomotor with brakes.
