4 INSTALLATION, WIRING, START-UP, AND MAINTENANCE

4.4.2 Trial operation and adjustment procedure

Servo start-up procedure
Turn OFF PLC system power supply
Check that the system power supply is
OFF.
Check wiring and module installation
(1) Check the installation position and
condition of each modules.
(2) Check the connecting condition of
connectors.
(3) Check that all terminal screws are tight.
(4) Check the ground wires of servo
amplifier, etc..
(5) Check the servomotor wiring (U, V, W).
(6) Check the regenerative resistor wiring.
(7) Check the circuit of emergency stop or
forced stop.
Servo amplifier setting
Set the axis number of servo amplifier.
Turn ON power supply
Set the switch of PLC CPU module to
STOP, and turn ON the system power
supply.
PLC parameter setting
Set the parameter setting using
GX Developer.
Turn ON power supply again
Turn ON again the power supply or reset of
system.
Check I/O module
Check the wiring of I/O modules.
1)
Refer to the QCPU User's Manual (Hardware Design,
Maintenance and Inspection) for installation of module.
Be sure to ground the controllers, servo amplifiers
and servomotors.
(Ground resistance: 100 or less)
Do not ground commonly with other devices.
Check that the combination of modules is correct.
Wrong combination may damage the modules.
Refer to Section 4.2.1
When using a regenerative resistor, shut the
power OFF with an error signal. The regenerative
resistor may abnormally overheat due to a fault in
the regenerative transistor, etc., and may lead to
fires.
Always take heat measure such as flame proofing
for the inside of the control panel where the servo
amplifier or regenerative resistor is mounted and
for the wires used. Failing to do so may lead to
fires.
Do not mount a phase advancing capacitor, surge
absorber or radio noise filter (option FR-BIF) on
the output side of the servo amplifier.
Correctly connect the output side (terminal U, V,
W). Incorrect connections will lead the servomotor
to operate abnormally.
