PA20 Alarms may not be avoided with the tough drive function depending on the situations of the power supply and load
fluctuation.
*TDS
You can assign MTTR (During tough drive) to pins CN1-13, CN1-14, CN1-22 to CN1-25, and CN1-49 with [Pr. PD23] to
Tough drive
[Pr. PD26], [Pr. PD28], and [Pr. PD47]. For MR-J4-03A6-RJ servo amplifiers, MTTR (During tough drive) cannot be
setting
assigned.
_ _ _ x For manufacturer setting
_ _ x _ Vibration tough drive selection
0: Disabled
1: Enabled
Selecting "1" enables to suppress vibrations by automatically changing setting values
of [Pr. PB13 Machine resonance suppression filter 1] and [Pr. PB15 Machine
resonance suppression filter 2] in case that the vibration exceed the value of the
oscillation level set in [Pr. PF23].
To output the oscillation detection alarm as a warning, set [Pr. PF24 Vibration tough
drive function selection].
For details, refer to section 7.3 of "MR-J4-_A_(-RJ) Servo Amplifier Instruction
Manual".
_ x _ _ SEMI-F47 function selection
0: Disabled
1: Enabled
Selecting "1" enables to avoid triggering [AL. 10 Undervoltage] using the electrical
energy charged in the capacitor in case that an instantaneous power failure occurs
during operation. In [Pr. PF25 SEMI-F47 function - Instantaneous power failure
detection time], set the time until the occurrence of [AL. 10.1 Voltage drop in the
control circuit power].
For MR-J4-03A6-RJ servo amplifiers, this digit cannot be used other than the initial
value.

When this digit is changed, the home position will be changed. Execute the home
position return again.
0: Electronic gear ([Pr. PA06] and [Pr. PA07])
1: Not used for positioning mode.
Setting this will trigger [AL. 37 Parameter error].
2: J3 electronic gear setting value compatibility mode
(Electronic gear ([Pr. PA06] and [Pr. PA07] × 16))
The electronic gear setting value can be used set with MR-J3.
3: J2S electronic gear setting value compatibility mode
(Electronic gear ([Pr. PA06] and [Pr. PA07] × 32))
The electronic gear setting value can be used set with MR-J2S.
For MR-J4-03A6-RJ servo amplifiers, "2" and "3" cannot be selected for this digit.
