Part 4: Review on Replacement of MR-J2S-_CP_/CL_ with MR-J4-_A_-RJ
MR-J2S-_CP_ or MR-J2S-_CL_
No. Name and function
16 Serial communication function selection - Alarm history
clear
Used to select the serial communication baud rate and
various conditions for communication, and to clear the
alarm history.
Serial communication baud rate selection
0: 9600 [bps]
1: 19200 [bps]
2: 38400 [bps]
3: 57600 [bps]
4: 4800 [bps] (for MR-DP60)
Alarm history clear
0: Disabled
1: Enabled
Selecting "Enabled" will erase the alarm
history at the next power-on. It will be
automatically disabled "0" after the alarm
history is erased.
Serial communication selection
0: Use RS-232C
1: Use RS-422
Serial communication response delayed time
0: Disabled
1: Enabled, reply after delay time of 800μs or
more.
17 Analog monitor output
Used to select the signals output to analog monitor 1
(MO1) and analog monitor 2 (MO2).

Note 1. Units used for MR-J2S-_CP_ or MR-J2S-_CL_ are different from those for MR-J4-_A_-RJ. Note that the input range of existing
equipment needs to be adjusted.
2. Set "0008" or "0009". When setting the value, note that the input range of existing equipment needs to be adjusted.
3. "Maximum speed" and " Maximum torque" differ depending on the servo motor. Therefore, after the existing servo motor has
been replaced with an HG motor, the output voltage for "Maximum speed" or " Maximum torque" may differ.
