MR-J2S-_A_
No. Name and function
66 Gain switching condition
Used to set the values for the gain switching conditions
(command frequency, droop pulses, and servo motor
speed) selected in [Pr. 65].
The set value unit differs depending on the switching
condition item.
Setting range: 0 to 9999
67 Gain switching time constant
Used to set the time constant at which the gains will
switch in response to the conditions set in [Pr. 65] and
[Pr. 66].
Setting range: 0 to 100
69 Command pulse multiplication numerator 2
Used to set a multiplier for the command pulse. When "0"
is set as the setting value, the resolution of the
connected motor is set automatically.
Setting range: 0 to 65535
When using this parameter, enable the CM1 and CM2
signals in [Pr. 43] to [Pr. 48].
70 Command pulse multiplication numerator 3
Used to set a multiplier for the command pulse. When "0"
is set as the setting value, the resolution of the
connected motor is set automatically.
Setting range: 0 to 65535
When using this parameter, enable the CM1 and CM2
signals in [Pr. 43] to [Pr. 48].
71 Command pulse multiplication numerator 4
Used to set a multiplier for the command pulse. When "0"
is set as the setting value, the resolution of the
connected motor is set automatically.
Setting range: 0 to 65535
When using this parameter, enable the CM1 and CM2
signals in [Pr. 43] to [Pr. 48].
72 Internal speed command 4
Used to set speed 4 of internal speed commands.
When using this parameter, enable the SP3 signal in [Pr.
43] to [Pr. 48].
Internal speed limit 4
Used to set speed 4 of internal speed limits.
When using this parameter, enable the SP3 signal in [Pr.
43] to [Pr. 48].

value
10 PB27 Gain switching condition
Used to set the values for the gain switching
conditions (command frequency, droop pulses, and
servo motor speed) selected in [Pr. PB26].
The set value unit differs depending on the switching
condition item.
Setting range: 0 to 9999
Set the same value as for MR-J2S-_A_.
1 PB28 Gain switching time constant
Used to set the time constant at which the gains will
switch in response to the conditions set in [Pr. PB26]
and [Pr. PB27].
Setting range: 0 to 100
Set the same value as for MR-J2S-_A_.
1 PC32 Commanded pulse multiplication numerators 2 to 4
To enable the parameter, select "Electronic gear (0
_ _ _)" or "J3A electronic gear setting value
compatibility mode (2 _ _ _)" in "Electronic gear
selection" in [Pr. PA21].
Setting range: 0 to 16777215
When using this parameter, enable the CM1 and
CM2 signals in [Pr. PD03] to [Pr. PD22].
1 PC33
Set as follows.
(1) For primary replacement
Set the same value as the setting value for MR-
J2S-_A_.
(2) For secondary/simultaneous replacement
Set a value 32 x the MR-J2S-_A_ setting value.
1 PC34
200 PC08 Internal speed command 4
This is used to set speed 4 of internal speed
commands.
When using this parameter, enable the SP3 signal in
[Pr. PD03] to [Pr. PD22].
Set the same value as for MR-J2S-_A_.
Internal speed limit 4
This is used to set speed 4 of internal speed limits.
When using this parameter, enable the SP3 signal in
[Pr. PD03] to [Pr. PD22].
Set the same value as for MR-J2S-_A_.
