18. MR-J4-03A6(-RJ) SERVO AMPLIFIER

18.4.1 Startup procedure

When switching power on for the first time, follow this section to make a startup.
01. Wiring check
02. Setting of main circuit
power supply selection
1. Turning on of control circuit
power supply
2. Setting of 24 V DC main circuit
power supply with [Pr. PC27]
3. Turning off of control
circuit power supply
4. Turning on of control
circuit power supply
Check of [Pr. PC27]
03. Recheck of main circuit power
supply voltage and wiring
04. Surrounding environment check
05. Turning on of main circuit
power supply
06. Parameter setting
07. Test operation of the servo
motor alone in test operation mode
08. Test operation of the servo
motor alone by command
09. Test operation with the servo
motor and machine connected
10. Gain adjustment
11. Actual operation
12. Stop
Check that the servo amplifiers and servo motors are wired correctly. (Refer
to section 18.4.3.)
Set the main circuit power supply selection (48 V DC or 24 V DC) to servo
amplifier. Set [Pr. PC27] according to the flow of 02-1 to 02-4.
Set this setting only when using 24 V DC.
(The initial value of the main circuit power supply selection is 48 V DC.
When using 48 V DC, turn the control circuit power supply on and move on
to procedure 03.)
To set the parameter to servo amplifier, turn on the control circuit power
supply. At this time, do not turn on the main circuit power supply.
Set [Pr. PC027] setting to "_ 1 _ _".
To reflect the parameter setting, turn off the control circuit power supply.
Turn on the control circuit power supply on again, and check that [Pr. PC27]
is changed to "24 V DC (_ 1 _ _)".
At this time, do not turn on the main circuit power supply.
Make sure that the main circuit power supply voltage of the servo amplifier to
be turned on matches with the voltage set by [Pr. PC27] and that the servo
amplifiers and servo motors are wired correctly by visual inspection, DO
forced output function (section 18.5.9), etc.
Check the surrounding environment of the servo amplifier and servo motor.
(Refer to section 18.4.4.)
Turn on the main circuit power.
Set the parameters as necessary, such as the used operation mode. (Refer
to sections 18.6, 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 servo system controller.
Make gain adjustment to optimize the machine motions. (Refer to chapter 6.)
Stop giving commands and stop operation. Other conditions that stop the
servo motor are mentioned in sections 4.2.2, 4.3.2, and 4.4.2.
