Ambient Environment - Mitsubishi Electric MELSERVO-J2S Series Manual

Precautions
*1. For the details of the setting and test operation of each servo amplifier and so forth, see technical materials on the MR-J4 servo amplifier issued by
Mitsubishi Electric Corporation.
If the existing servo amplifier has an extremely high gain, the characteristics may slightly vary after a primary replacement. Make sure to readjust the gain
setting.
*2. When turning on the power source to the system, turn on the 24V DC power to the external interface at the same time. Otherwise, AL.E6.1 occurs.
*3. When you perform a secondary/package replacement, the monitor output (the rotational speed of the motor) will be different from the existing amplifier.
If you are using the monitor output with the existing system, note that you need to change the program.
(Example: If you replace HC-KFS13 with HG-KR13, the output voltage of the rotational speed of the monitored motor will be 3/4 of that with J2S.)

Ambient Environment

（１）Arrangement of Cables
（ａ）No excessive force must be applied on the wiring cables.
（ｂ）The encoder cable must not exceed the lifetime of its flexibility.
（ｃ）No excessive force must be applied on the connector of the servomotor.
（２）Environment
The signal cables and the power cables in any part must not be short-circuited due to wire dust, metal
dust, or the like.
