5. OPERATION 5. OPERATION
WARNING Do not operate the switches with wet hands. You may get an electric shock.
CAUTION
Before starting operation, check the param eters. Some machines may perform
unexpected operation.
Take safety measures, e.g. provide covers, to pr event accidental contact of hands
and parts (cables, etc.) with the servo ampl ifier heat sink, regenerative resistor,
servo motor, etc. since they may be hot while power is on or for some time after
power-off. Their temperatures may be high and you may get burnt or a parts may
damaged.
During operation, never touch the rotating parts of the servo motor. Doing so can
cause injury.
5.1 Switching power on for the first time
When switching power on for the first time, f ollow this section to make a startup.
5.1.1 Startup procedure
Wiring check
Check whether the servo amplifier and servo motor are wired
correctly using visual inspection, DO forced output func tion
(Section 7.7.4, 8.5.7 (4)), etc. (Refer to sectio n 5.1.2.)
Surrounding environment check
Check the surrounding environment of the servo amplif ier and
servo motor. (Refer to section 5.1.3.)
Parameter setting
Set the parameters as necessary, such as the used contr ol
mode and regenerative option selection with the param eter unit
or MR Configurator. (Refer to chapter 6.)
Test operation of servo motor
alone in test operation mode
For the test operation, with the servo motor disconnec ted from
the machine and operated at the speed as low as p ossible, and
check whether the servo motor rotates correctly. (Refer to
sections 7.7 and 8.5.7.)
Test operation of servo motor
alone by commands
For the test operation with the servo motor disc onnected from
the machine and operated at the speed as low as p ossible, and
check whether the servo motor rotates correctly.
Test operation with servo motor
and machine connected
Connect the servo motor with the machine, give operatio n
commands from the host command device, and c heck machine
motions.
Gain adjustment
Make gain adjustment to optimize the machine motions. ( Refer
to chapter 9.)
Actual operation
Stop Stop giving commands and stop operation.
