(3) For simultaneous replacement
The following parameters 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. For details,
refer to Part 2 Section 3.6 .
Parameter
number
Setting item Setting value Description
Changing required.
PA04 Function selection A-1 0000h Forced stop deceleration function selection
To configure the same settings as those for MR-J2S, select "Forced stop
deceleration function disabled (EM1)".
PA09 Auto Tuning Response 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 Manual.
PD27 Output device selection 2
* 11 kW or more, only when
using this function
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.
PD03 to 14 Input signal device selection - When the assignment of the Input/output signal for the existing MR-J2S servo
amplifier, setting is required.
For details, refer to Part 2 Section 3.6.
Position control mode only
PA06 Electronic gear numerator (CMX)
(Command input pulse
multiplication numerator) 8
(Note 1)
When using an electronic gear, it is necessary to change the setting value.
Set the same value as [Pr. 3] or [Pr. 4] of for the MR-J2S-_A_ servo amplifier.
PA07 Electronic gear denominator
(CDV)
(Commanded pulse
multiplication denominator)
1
(Note 1)
PA21 Electronic gear selection 3001h J2S electronic gear setting value compatibility mode
Magnify the electronic gear setting value by 32 times.
PA13 Command pulse input form _ 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.
PA10 In-position range 100
(Note 2)
In-position range
Used to set an in-position range per command pulse unit.
Set the value of [Pr. 5] for the MR-J2S-_A servo amplifier in this parameter as
well.
Speed control mode only
PA01 Control mode _ _ _ 2h Select the servo amplifier control mode.
Select the speed control mode.
PC12 Analog speed command -
Maximum speed 3000 Analog speed command - Maximum speed
The setting value at left is for when the HC-SFS53 motor is replaced with the HG-
SR52 motor.
Torque control mode only
PA01 Control mode _ _ _ 4h Select the servo amplifier control mode.
Select the torque control mode.
PC12 Analog speed limit - Maximum
speed 3000 Analog speed limit - Maximum speed
The setting value at left is for when the HC-SFS53 motor is replaced with the HG-
SR52 motor.
PC13 Analog torque command
maximum output 100 Analog torque command maximum output
Set the same value as for the MR-J2S-_A_ servo amplifier.
When using encoder output pulses
PA15 Encoder output pulses 128
(Note 3)
Used to set the encoder pulses (A-phase and B-phase) output by the servo amplifier.
PC19 Encoder output pulse setting
selection 0 _ 1 _ h
(Note 3)
Encoder output pulse setting selection
Used to set the encoder pulses output by the servo amplifier.
The setting value at left is according to the dividing ratio setting.
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 output pulse setting of an existing HC-KFS motor (encoder resolution: 131072
pulses/rev) is "Dividing ratio: 1/4".
