3.1.1 Step 1: Trial Operation for Servomotor without Load
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 possible in
step 1 (prior to connecting the servomotor to equipment).
Conduct a test run for the motor without load according to the following procedure. See
3.2.1 Servomotors with Brakes if you are using a servomotor with brakes.
1. Secure the servomotor.
Secure the servomotor mounting plate to the
equipment in order to prevent the servomotor
from moving during operation. In this case,
be sure to disconnect the coupling and belt.
2. Check the wiring.
Disconnect the CN1 connector and check servomo-
tor wiring in the power supply circuit. CN1 I/O sig-
nals are not used, so leave the connector
disconnected.
Do not connect to the equipment.
Operate the motor
with a Digital Operator.
Check wiring.
