Detailed list of parameters
• For parameters which are not described in this section, refer to chapter 5 of "MR-J4-_GF_(-RJ) Servo
Amplifier Instruction Manual (Motion Mode)".
• Set a value to each "x" in the "Setting digit" columns.
• The symbol in the control mode column means as follows:
CP: Point table method
PS: Indexer method

7.2 Detailed list of parameters
Function
Control mode selection
Select a control mode.
0: Positioning mode (point table method)
8: Positioning mode (indexer method)
Operation mode selection
0: Standard control mode
1: Fully closed loop control mode
4: Linear servo motor control mode
6: DD motor control mode
The following settings will trigger [AL. 37 Parameter error].
• A value other than "0", "1", "4", and "6" is set to this digit.
• When set to positioning mode (indexer method), a value other than "0" and "6" is set to this digit.
For manufacturer setting
Set an electronic gear numerator. (Refer to section 7.2.6.)
Set the electronic gear within the following range. Setting out of the range will trigger [AL. 37
Parameter error].
1/865 < CMX/CDV < 271471
Setting range: 1 to 16777215
Set the number of gear teeth on machine side. (Refer to section 7.2.6.)
Set the electronic gear within the following range. Setting out of the range will trigger [AL. 37
Parameter error].

When a small value is set to the electronic gear ratio with the manual operation mode, the servo
motor may not operate at the set servo motor speed.
Travel distance of one station = Pt (servo motor resolution) ×
Setting range: 1 to 16777215
Set an electronic gear denominator. (Refer to section 7.2.6.)
Set the electronic gear within the range of [Pr. PA06].
Setting out of the range will trigger [AL. 37 Parameter error].
Setting range: 1 to 16777215
Set the number of gear teeth on servo motor side. (Refer to section 7.2.6.)
Set the electronic gear within the range of [Pr. PA06]. Setting out of the range will trigger [AL. 37
