4.1.1 Trial Operation for Servomotor Without Load
In this section, confirm the cable connections of the main circuit power supply, servomotor and encoder.
Incorrect wiring is generally the reason why servomotors fail to operate properly during the trial
operation.
Confirm the wiring, and then conduct the trial operation for servomotor without load according to the
following steps.
10
Set necessary
parameters.
Using the same procedure as you did to input a reference in step 8,operate
the servomotor via the host controller and set the parameter to make sure
the machine’s
travel direction, travel distance, and travel speed
all
correspond to the reference.

Operation
The servomotor can now be operated. Adjust the servo gain if necessary.

C A U T ION
·Release the coupling between the servomotor and the machine, and secure only the servomotor
without a load.
·To prevent accidents, initially perform the trial operation for servomotor under no-load conditions
(with all couplings and belts disconnected).

1
Secure the servomotor.
Secure the servomotor
flange to the m achine .
D o not connect anything to the
shaft ( n o -load conditions
) .
Secure the servomotor flange to the machine
in order to prevent the servomotor from
moving during operation.
Do not connect the servomotor shaft to the
machine. The servomotor may tip over during
rotation.
2
Check the power supply circuit, servomotor, and
encoder wiring.
With the I/O signal connector (CN1)
disconnected, check the power supply circuit
and servomotor wiring.
