PA20 *TDS Tough drive setting
Alarms may not be avoided with the tough drive function depending on the situations of the
power supply and load fluctuation.
You can assign MTTR (During tough drive) to pins CN3-9 and CN3-13 with [Pr. PD07] and [Pr.
PD08].

3.2.2 Gain/filter setting parameters ([Pr. PB_ _ ])

Details of Gain/filter setting parameters ([Pr. PB_ _ ]) are the same as those for MR-J4-_B_ servo amplifier.
Refer to section 5.2.2 of "MR-J4-_B_(-RJ) Servo Amplifier Instruction Manual".
Name and function
Explanation
For manufacturer setting
Vibration tough drive selection
0: Disabled
1: Enabled
Selecting "1" enables to suppress vibrations by automatically
changing the setting values of [Pr. PB13 Machine resonance
suppression filter 1] and [Pr. PB15 Machine resonance suppression
filter 2] in case that the vibration exceeds the value of the oscillation
level set in [Pr. PF23].
For details, refer to section 7.3 of "MR-J4-_B_(-RJ) Servo Amplifier
Instruction Manual".
This cannot be used in the pressure control mode.
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. The time until
[AL. 10.1 Voltage drop in the control circuit power] occurs can be
set with [Pr. PF25 SEMI-F47 function - Instantaneous power failure
detection time].
