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 24 V DC power supply for the external interface. Otherwise, AL. E6.1
occurs.
Do not operate the switches with wet hands. Otherwise, it may cause an electric
shock.
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,
example, provide covers to avoid accidentally touching the parts (cables, etc.) by
hand. Otherwise, it may cause a burn injury and parts damaged.
During operation, never touch the rotor of the servo motor. Otherwise, it may
cause injury.
... Confirm the parameter settings of the currently used MR-J2S servo amplifier with
the display or with the setup software and record them.
... Visually verify that the wires are correctly connected to the servo amplifier and the
servo motor.
... Check the surrounding environment of the servo amplifier and servo motor.
... Set the parameters as necessary, such as the used control mode and regenerative
option selection. (Refer to this Replacement Manual.)
... 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.
... 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 to the machine, check the motions of the machine
by sending operation commands from a higher-level command-issuing device.
... Make gain adjustment to optimize the machine motions.
... Perform a home position return as necessary when in position control mode.
... Stop giving commands and stop operation. In addition, check the conditions when
the servo motor operation stops.
