Comparison Of Parameters; Setting Requisite Parameters Upon Replacement - Mitsubishi Electric MELSERVO-J4 Series Transition Handbook

Part 6: Review on Replacement of MR-J3-_T_(DIO command/ Serial communication operation) 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
simultaneous replacement. Depending on the settings of the currently used amplifier, parameters other than
these may need to be set.
MR-J3-_T_
(DIO command/Serial communication operation)
No. Name
PA01 Control mode
PA02 Regenerative option
PA03 Absolute position detection system
PA04 Function selection A-1
PA05 Feeding function selection
PA06 Electronic gear numerator
(Command input pulse multiplication
numerator)
PA07 Electronic gear denominator
(Command pulse multiplying factor
denominator)
PA08 Auto tuning
PA09 Auto tuning response
PA10 In-position range
PA11 Forward torque limit
PA12 Reverse torque limit
Rotation direction selection
PA14
PA15 Encoder output pulses
PA19 Parameter write inhibit
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 factory
settings. To disable the deceleration to a stop function, set [Pr. PA04] to "0 _ _
_".
To enable read/write the positioning control parameters ([Pr. PT_ _ ]), set [Pr.
PA19 Parameter writing inhibit] to "0 0 A B".
