WARNING
Do not operate the switches with wet hands. Otherwise, it may cause an electric
shock.
CAUTION
Before starting operation, check the parameters. Improper settings may cause
some machines to operate unexpectedly.
The servo amplifier heat sink, regenerative resistor, servo motor, etc. may be hot
while power is on or for some time after power-off. Take safety measures, e.g.
provide covers, to prevent accidental contact of hands and parts (cables, etc.)
with them.
During operation, never touch the rotor of the servo motor. Otherwise, it may
cause injury.
4.1 Switching power on for the first time
When switching power on for the first time, follow this section to make a startup.
4.1.1 Startup procedure
Check whether the servo amplifier and servo motor are wired correctly using
visual inspection, DO forced output function (section 4.5.8), etc. (Refer to
section 4.1.2)
Check the surrounding environment of the servo amplifier and servo motor.
(Refer to section 4.1.3)
Set the parameters as necessary, such as the used operation mode and
regenerative option selection. (Refer to chapter 5, and sections 4.2.4, 4.3.4,
and 4.4.4.)
For the test operation, with the servo motor disconnected from the machine
and operated at the speed as low as possible, check whether the servo
motor rotates correctly. (Refer to sections 4.2.3, 4.3.3, and 4.4.3.)
For the test operation with the servo motor disconnected from the machine
and operated at the speed as low as possible, give commands to the servo
amplifier and check whether the servo motor rotates correctly.
After connecting the servo motor with the machine, check machine motions
with sending operation commands from the controller.
Make gain adjustment to optimize the machine motions. (Refer to chapter 6.)
Stop giving commands and stop operation. Other conditions that stops the
servo motor are mentioned in sections 4.2.2, 4.3.2, and 4.4.2.
