  1. Servo Movement

     Would this setting change after an encoder swap? There has been no changes to this machine except an encoder change in the last 5 years. This issue just started happening within the last couple of months.
  2. Servo Movement

    I have a machine that has been in operation for more than six years. It uses a Mitsubishi MR-J2S-350B servo amplifier and a Mitsubishi QD75M2 positioning module. When the control power is turn off for more than 30 minutes the servo will move when power is restored to the amplifier. The unit moves down to position -30. Then you have to manually jog the servo to -29 before you are able to send the unit to home position. This issue just started a couple of months ago. The machine is powered down each night for PMs and has to be homed every morning. I have changed the battery.
