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 CN1-23, CN1-24, and CN1-49 with [Pr. PD24], [Pr. PD25], and 
[Pr. PD28].

_ _ x _  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]. 
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-JE-_A Servo Amplifier Instruction Manual". 
0h 
   
  _ x _ _  Instantaneous power failure tough drive selection 
0: Disabled 
1: Enabled 
 
Selecting "1" enables to avoid triggering [AL. 10 Undervoltage] by using the 
electrical energy charged in the capacitor in the servo amplifier in case that an 
instantaneous power failure occurs during operation. Set the time until the 
occurrence of [AL. 10.1 Voltage drop in the power] with [Pr. PF25 Instantaneous 
power failure tough drive - Detection time]. 
When "1" is selected for this digit, the power should be off for the setting value of [Pr. 
PF25] + 1 s or more before cycling the power to enable a parameter whose symbol 
is preceded by "*".

When this digit is changed, the home position will be changed. Execute the home 
position return again.

_ _ x x  Alarm detail No. setting 
Set the digits when you execute the trigger with arbitrary alarm detail No. for the 
drive recorder function. 
When these digits are "0 0", only the arbitrary alarm No. setting will be enabled.

x x _ _  Alarm No. setting 
Set the digits when you execute the trigger with arbitrary alarm No. for the drive 
recorder function. 
When "0 0" are set, arbitrary alarm trigger of the drive recorder will be disabled.

 Setting example: 
To activate the drive recorder when [AL. 50 Overload 1] occurs, set "5 0 0 0". 
To activate the drive recorder when [AL. 50.3 Thermal overload error 4 during operation] occurs, set "5 0 0 3".
