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

Part 3: Review on Replacement of MR-J2S-_B_ with MR-J4-_B_

3.7.1 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.

Name
The setting must be changed according to option model.
Forced stop deceleration function selection
To configure the same settings as for MR-J2S-_B_, select "Forced stop
deceleration function disabled (with EM1 used)".
The setting value needs to be changed according to the auto tuning mode.
Auto tuning response setting
Refer to "3.7.3 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 on how to make gain adjustments, refer to Chapter 6 of the MR-
J4-_B_ Servo Amplifier Instruction Manual. The setting value needs be
changed based on the standard machine resonance frequency.
The setting needs to be changed depending on the servo motor.
Used to set the encoder pulses (A-phase and B-phase) output by the servo
amplifier.
Change the setting value as necessary.
The unit system is different. (0.1-fold→0.01-fold) Pay attention to setting

The setting value must be changed according to monitor output data.
"Maximum speed" and "Maximum torque" differ depending on the servo
motor. Set according to the servo motor.
Depends on hardware. It is necessary to change the setting value.
Depends on hardware. It is necessary to change the setting value.
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.
