Scale Measurement Encoders - Mitsubishi Electric MELSERVO-J5 User Manual

Scale measurement encoders

Precautions
Contact the manufacturer of the scale measurement encoder being used for information on specifications, performance and
guarantees.
Linear encoders
Refer to the following manual for linear encoders that can be used as a scale measurement encoder.
MR-J5 Partner's Encoder User's Manual
To use [Pr. PA22.3 Scale measurement function selection] by setting it to "1" (use with absolute position detection system), an
absolute position type linear encoder is required. In this case, the encoder battery need not be mounted to the servo amplifier
to hold the load-side absolute position data.
Rotary encoders
If using a rotary encoder as a scale measurement encoder, use the following motor as the encoder.
Servo amplifier
MR-J5-_G_/MR-J5-_B_
MR-J5-_G_-RJ_/MR-J5D1-_G_/MR-J5-_B_-RJ
MR-J5W2-_G_/MR-J5D2-_G_/MR-J5W2-_B_
For the MR-J5-_G_, MR-J5W2-_G_, MR-J5D1-_G_, MR-J5D2-_G_, MR-J5-_B_, and MR-J5W2-_B_, use two-wire type
encoder cables.
If using [Pr. PA22.3 Scale measurement function selection] by setting it to "1" (use with absolute position detection system)
and connecting a battery backup type rotary encoder to the servo amplifier, an encoder battery must be mounted to the servo
amplifier to hold the load-side absolute position data. In this case, the battery life will be shorten because the current
consumption is increased as the power from the battery is supplied to both the servo motor-side and the load-side encoder. If
connecting a batteryless rotary encoder to the servo amplifier, the encoder battery need not be mounted to the servo amplifier.
For A/B/Z-phase differential output type rotary encoders, refer to "A/B/Z-phase differential output type encoder" in the
following manual.
