7. PARAMETER SETTING
7.1 List of General-Purpose Interface Setting Requisite Parameters
(1) For primary replacement
The following parameters are a minimum number of parameters that need to be set for primary
replacement. Depending on the settings of the currently used servo amplifier, parameters other than
these may need to be set. For details, refer to Part 2 Section 3.6.
Parameter
Setting item
number
Changing required.
PA04 Function selection A-1
PC22 Function selection C-1
PA09 Auto Tuning Response
PD27 Output device selection 2
* 11 kW or more, only when
using this function
PD03 to PD14 Input signal device selection
Position control mode only
PA06 Electronic gear numerator (CMX)
(Command input pulse
multiplication numerator)
PA07 Electronic gear denominator
(CDV)
(Commanded pulse
multiplication denominator)
PA21 Electronic gear selection
PA13 Command pulse input form
PA10 In-position range
Speed control mode only
PA01 Control mode
PC12 Analog speed command -
Maximum speed
Note 1. The example value shown is for when the electronic gear setting of an existing servo amplifier is set as "8/1".
2. The example value shown is for when the in-position range of an existing servo amplifier is set as "100".
3. The example value shown is for when the servo amplifier setting of an existing servo amplifier is set as "3000".
Setting value
0000h Forced stop deceleration function selection
To configure the same settings as those for MR-J2S, select "Forced stop
deceleration function disabled (EM1)".
_ 1 _ _ h Serial encoder selection.
This setting is for communication with the encoder of MR-J2S. An incorrect setting
causes encoder initial communication data error 1 (AL.20.1).
8 Auto tuning response setting
When replacing, switch the power on after setting the parameter value to "8".
* It is necessary to make gain adjustment again when replacing.
The setting value of this parameter is equivalent to the slow response of the MR-
J2S. Perform adjustment since tha gain can be too low for the slow response.
For details on how to make gain adjustments, refer to Chapter 6 of the MR-J4
Servo Amplifier Instruction
0006h Dynamic brake interlock (DB) selection)
When using this function for the MR-J2S servo amplifier of 11 kW or more, set the
parameter. Assign a DB signal to pin CN1-48.
- When the assignment of the Input/output signal for the existing MR-J2S servo
amplifier is changed, setting is required.
For details, refer to Section 5.2 in "Manual for Replacement from MR-J2S Renewal
Tool (X903120707)" issued by Mitsubishi Electric System & Service Co., Ltd.
8 When using an electronic gear, it is necessary to change the setting value.
(Note 1) Set the same value as [Pr. 3] or [Pr. 4] of for the MR-J2S-_A_ servo amplifier.

(Note 1)
0001h A setting value for the electronic gear [Pr. PA06] or [Pr. PA07] becomes effective.
_ 2 _ _ h Pulse train filter selection
The setting value mentioned at the left side is a command pulse train filter setting
equivalent to the MR-J2S-_A_ (when setting the differential line driver type).
* If it is not set, position mismatch will occur. Make sure to set a filter.
In addition, it is necessary to adjust the command pulse logic to the positioning
module. For details, refer to Part 2 Section 3.7.
* An incorrect logic setting causes the servo motor to not rotate. Make sure
to configure the settings.
100 In-position range
(Note 2) Used to set an in-position range per command pulse unit.
Set the same value as [Pr. 5] of for the MR-J2S-_A_ servo amplifier.
_ _ _ 2h Select the servo amplifier control mode.
Select the speed control mode.
3000 Analog speed command - Maximum speed
