Comparison Of Parameters; Setting Requisite Parameters Upon Replacement - Mitsubishi Electric MELSERVO-J2S Series Transition Handbook

Part 4: Review on Replacement of MR-J2S-_CP_/CL_ with MR-J4-_A_-RJ

3.6 Comparison of Parameters

CAUTION

3.6.1 Setting requisite parameters upon replacement

The parameters shown in this section are a minimum number of parameters that need to be set for
replacement. Depending on the settings of the currently used servo amplifier, parameters other than these
may need to be set.
(1) Common when replacing MR-J2S-_CP_/MR-J2S-_CL_
(a) Simultaneous replacement with MR-J4-_A_-RJ and an HG motor
Parameter
number
PA04 Function selection A-1
PA06 Electronic gear numerator
(Commanded pulse
multiplication numerator)
PA07 Electronic gear denominator
(Commanded pulse
multiplication denominator)
PA21 Function selection A-3
PA09 Auto tuning response
Note. The example value shown is for when the electronic gear ratio of an existing servo amplifier is set as "8/1".
Never perform extreme adjustments and changes to the parameters, otherwise
the operation may become unstable.
If fixed values are written in the digits of a parameter, do not change these values.
Do not change parameters for manufacturer setting.
Do not enter any setting value other than those specified for each parameter.
POINT
For the parameter converter function, refer to "Part 7: Common Reference
Material".
To enable a parameter whose abbreviation is preceded by *, turn the power OFF
and then ON after setting the parameter.
For details about parameter settings for replacement, refer to the MR-J4-_A_-RJ
Servo Amplifier Instruction Manual (POSITIONING MODE).
With MR-J4-_A_-RJ, the deceleration to a stop function is enabled by the factory
setting. To disable the deceleration to a stop function, set [Pr. PA04] to "0 _ _ _".
Wiring of the CN1-42 pin is required for the MR-J4-_A_-RJ regardless of the
setting value of [Pr. PA04: Forced stop deceleration function selection]. Refer to
"3.3 List of Corresponding Connectors and Terminal Blocks" for details
regarding wiring.

8 When using an electronic gear, it is necessary to change the
setting value.
(Note)
Set the electronic gear ratio of an existing servo amplifier when
simultaneously replacing with MR-J4-_A_-RJ and an HG motor.

When a geared servo motor is replaced, the actual reduction
(Note)
ratio may differ before and after the replacement. If the ratio
differs after the replacement, set the values considering the
actual reduction ratio.
3 0 0 1h Electronic gear selection
Select "J2S electronic gear setting value compatibility mode" to
continue using the electronic gear ratio set in MR-J2S-
_CP_/MR-J2S-_CL_.
8 Auto tuning response setting
Enter this setting value for replacement, referring to "3.6.3
Comparison of parameter details".
It is necessary to make gain adjustment again when replacing.
For details about gain adjustment, refer to "MR-J2S-_CP_ [Pr. 3]
(MR-J4-_A_ [Pr. PA09])" in Section 3.6.3.
