BCSD-48/116 Digital Brushless AC Servo Drive system - Ref. 1809
4.1.1. Trial Operation for Servomotor Without Load
CAUTION
• 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).
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.
Step Description Check Method and Remarks
1
Secure the servomotor. 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.
Refer to 3.1 Main Circuit Wiring.
3
Turn ON the control power supply and main circuit
power supply.
Normal Display:
Alternate Display
Example of Alarm Display:
If the power is correctly supplied, the panel
operator display on the front panel of the
servodrive will appear as shown on the left. The
display on the left indicates that forward run
prohibited (P-OT) and reverse run prohibited (N-
OT).
If an alarm display appears, the power supply
circuit, servomotor wiring, or encoder wiring is
incorrect. If an alarm is displayed, turn OFF the
power, find the problem, and correct it.
4
Release the brake before driving the servomotor
when a servomotor with brake is used.
