1.1 Switching power on for the first time
When switching power on for the first time, follow this section to make a startup.
1.1.1 Startup procedure
Parameter settings check for the
currently used model
・・・
Confirm the parameter settings of the currently used MR-J3/MR-J3W servo amplifier
with the display or with the setup software and record them.
↓
Wiring check
・・・
Visually verify that the wires are correctly connected to the servo amplifier and the servo
motor.
↓
Surrounding environment check
・・・
Check the surrounding environment of the servo amplifier and servo motor.
↓
Parameter setting (Note 1)
・・・
Set the parameters as necessary, such as the used control mode and regenerative
option selection. (Refer to this Replacement Manual.)
↓
Test operation of the servo motor
・・・ 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.
alone in the test operation mode
(Note 1, 2)
↓
Test operation with the servo motor
and machine connected
・・・
After connecting the servo motor to the machine, check the motions of the machine by
sending operation commands from a higher-level command-issuing device.
↓
Gain adjustment (Note 1)
・・・
Make gain adjustment to optimize the machine motions.
↓
Actual operation (Note 2)
・・・
Perform a home position return as necessary when in position control mode.
↓
Stop
・・・ Stop giving commands and stop operation. In addition, check the conditions when the
servo motor operation stops.
Note 1. For details about the settings for each servo amplifier and its test operation, refer to the applicable Servo Amplifier Instruction
Manual. If the gain of the existing servo amplifier is extremely high, there may be slight differences in characteristics upon
primary replacement. Make sure to set the gain again.
2. When turning on the power supply, also turn on the 24V DC power supply for the external interface. Otherwise, AL. E6.1
occurs.
