Configuring Mitsubishi MR-J4 Driver

With the MR J4 configuration you need to pay attention to two main parameters:

+ PA1: Servo control mode selection > Set to “1000” to select the position control mode.

+ PA5: Number of command Input pulses per Revolution = 1000PLS / 1REV

+ PA6/7: CMX / CDV: Input pulse gain ratio. Used to correct the change of the number of pulses / revolutions when issuing a command from the PLC to the Servo. The default is 1/1, which corresponds to 131072 pulses / rev.

+ PA13-PLSS Selection of control pulse types: Default is 0100, change the following two factors to select pulse input type.
