(Note-1): When "1: External input signal of servo amplifier" is set in "[Pr.80] External input signal selection"
at MR-JE-B use, the axis error or warning does not occur and the external signal (upper/lower
limit switch, near-point dog) cannot be operated. Refer to Section 14.4 "External signal selection
function" for the program example and system configuration when "2: Buffer memory of
QD77MS" is set.
(Note-2): Operates artificially as the following servo amplifier and servo motor during amplifier-less
operation mode.
Servo amplifier type: MR-J4-10B
Motor type: HG-KR053 (Resolution per servo motor rotation: 4194304 pulses)
Important
The servo amplifier MR-JE-B is integrated with the main circuit power supply and
the control power supply.
Therefore, when the power of the servo amplifier is turned OFF, the controller
cannot communicate with the axes after the axis whose power is turned OFF.
