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

Part 2: Review on Replacement of MR-J2S-_A_ with MR-J4-_A_

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
simultaneous replacement. Depending on the settings of the currently used servo amplifier, parameters other
than these may need to be set.
(1) Parameters common to position control mode, speed control mode, and torque control mode
Parameter Name
number
PA04 Function selection A-1
PA09 Auto tuning response
PA15 Encoder output pulse
PC19 Encoder output pulse
selection
PD30 Function selection D-1
Note. The example value shown is for when the output pulse setting of an existing HC-KFS motor (encoder resolution: 131072
pulses/rev) is "Dividing ratio: 1/4".
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_
Servo Amplifier Instruction Manual.
With MR-J4-_A_, the deceleration to a stop function is enabled by factory
settings. To disable the deceleration to a stop function, set [Pr. PA04] to "0 _ _ _".

To configure the same settings as for MR-J2S-_A_, select
"Forced stop deceleration function disabled (EM1)".
8 Auto tuning response setting
Refer to "3.6.3 Comparison of parameter details" for the
setting value of this parameter upon replacement.
It is necessary to make gain adjustment again when
replacing.
For details about gain adjustment, refer to "MR-J2S-_A_
[Pr. 2] (MR-J4-_A_ [Pr. PA09])" in Section 3.6.3.
128 (Note) Used to set the encoder pulses (A-phase and B-phase)
output by the servo amplifier.
0 _ 1_h Encoder output pulse selection
(Note)
Used to set the encoder pulses output by the servo
amplifier.
The setting value at left is according to the dividing ratio
setting.
1 _ _ _h This is used to select enabled or disabled for the thermistor
of the servo motor.
：When using (HA-LFS series) servo motors that have
thermal terminals and not connecting thermal signals to
the MR-J4 servo amplifier, set this parameter to "1 _ _ _h
(Disabled)".
The overheat protection of a servo motor is not enabled.
Configure a protective circuit.
