Connectors and pin assignments
The front view of the servo amplifier shown below is of MR-JET-_G_ servo amplifier with a rated capacity symbol of 40 or less.
Refer to the following for the appearance and connector layout of the other servo amplifiers.
The frames of the CN2 and CN3 connectors are connected to the protective earth terminal in the servo amplifier.
• Assignment of CN3 connector pins
The following diagram is the servo amplifier as viewed from the top.
*1 THM1 and THM2 are for connecting a servo motor thermistor. These signals can be used on servo amplifiers with firmware version B2
or later.
• Assignment of CN2 connector pins
The following diagram is the servo amplifier as viewed from the bottom.
*1 When using an A/B/Z-phase differential output type encoder, set [Pr. PC26.0 A/B/Z-phase input encoder connection setting selection] to
"2 (enabled)". [Pr. PC26.0] can be used on servo amplifiers with firmware version B2 or later.
