Setting Up Parameters; Table Of The Parameters You Need To Set Up - Type A - Mitsubishi Electric MELSERVO-J2S Series Manual

４.２ Setting Up Parameters
４.２.１ Table of the Parameters You Need to Set Up - Type A
（１）In the Case of Primary Replacement
* Listed below in the table are the parameters you, at least, need to set up when performing a primary replacement.
You may need to set up parameters other than the parameters listed below depending on the setting of the existing
amplifier. For the details, see "Guide for Replacing MR-J2S/J2M Series with J4 Series L(NA)03093", Part 2,
Section 3.5.
Parameter No.
*Required
PA04 Function selection A-1
PC22 Function selection C-1
PA09 Automatic tuning response
PD27
Output device selection 2
*For position control mode only
PA06 Electronic gear numerator (CMX)
(Numerator of the increment of the
command input pulse)
PA07 Electronic gear denominator (CDV)
(Denominator of the increment of
the command input pulse)
PA13 Input form of command pulse
PA10 In-position range
*For speed control mode only
PA01 Control mode
PC12 Maximum rotational speed of analog
speed command
*For torque control mode only
PA01 Control mode
PC12 Maximum rotational speed of analog
speed limit
PC13 Maximum output of analog torque
command
Note 1 This is an example of the case where the electronic gear of the existing servo amplifier is set to "8/1".
Note 2 This is an example of the case where the in-position range of the existing servo amplifier is set to "100".
Note 3 This is an example of the case where the setting of the existing servo amplifier is "3000".
Setting Item
* For 11kW or higher only when this
function is used
Setting
0000h Selection of forced stop/deceleration function
To make the same setting as MR-J2S, select "Forced stop/deceleration function not valid
(EM1 is used)."
□1□□h Selection of serial encoder
This is a setting for communications with the encoder of MR-J2S. If you do not make a
correct setting, the encoder causes an initial communication data error 1 (AL 16.1).
8 Automatic tuning response setting
After replacement, set "8" to this setting. Turn on the system.
* After replacement, you need to readjust the gain. This setting is equivalent to the low
response of MR-J2S. The low response may make the gain too low. Make adjustment.
For the details of how to adjust gains, see Section 6 in "Model MR-J4-_A(-RJ) SERVO
AMPLIFIER INSTRUCTION MANUAL" issued by Mitsubishi Electric Corporation.
0006h
Selection of dynamic brake interlock (DB)
If you use this function with MR-J2S of 11kW or higher, set up this parameter. DB
signals are assigned to the CN1-48 pins.
8 If you use an electronic gear, you need to change the setting.
(Note 1) If you perform a primary replacement, specify the same numbers as those of parameter Nos.
3 and 4 of the MR-J2S-_A servo amplifier.
1
(Note 1)
□2□□h Selection of pulse row filter
The setting shown in the left-side column is a filter setting of the command pulse row that
is equivalent to that with MR-J2S-_A (when the differential line driver type is set).
*Make sure to set up the filter. Otherwise, positioning may be incorrect.
In addition, you need to make the logic of the command pulse correspond to the positioning
module. For the details, see section 2.6.5.
*If you do not set up the logic, the motor will not turn. Make sure to make the setting.
100 In-position range
(Note 2) Set up the in-position range in the unit of a command pulse.
Specify the same number as that of parameter No. 5 of the MR-J2S-_A servo amplifier.
□□□2h Select the control mode of the servo amplifier.
The speed control mode is set.
3000 Maximum rotational speed of analog speed command
（Note 3）
□□□4h Select the control mode of the servo amplifier.
The torque control mode is set.
3000 Maximum rotational speed of analog speed limit
（Note 3）
100 Maximum output of analog torque command
Specify the same number as that of the MR-J2S-_A servo amplifier.
