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 For manufacturer setting 0h
_ _ 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.

alarm trigger
setting
_ _ 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.
00h
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.
00h
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".
