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, CN3-13, and CN3-15
with [Pr. PD07] to [Pr. PD09].
For MR-J4W2-0303B6 servo amplifiers, MTTR (during tough drive) cannot be
assigned. Refer to Name and

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 exceeds the value of the oscillation level set in
[Pr. PX26].
Refer to (8) of this section for details.

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. PX28 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-J4W2-0303B6 servo amplifiers, this digit cannot
be used other than the initial value.

PX26 OSCL1 Vibration tough drive - Oscillation detection level
Set a filter readjustment sensitivity of [Pr. PB13 Machine resonance suppression
filter 1] and [Pr. PB15 Machine resonance suppression filter 2] while the vibration
tough drive is enabled.
However, setting "0" will be 50%.
Example: When you set "50" to the parameter, the filter will be readjusted at the
time of 50% or more oscillation level.

Select alarm or warning when an oscillation continues at
a filter readjustment sensitivity level of [Pr. PX26].
The digit is continuously enabled regardless of the
vibration tough drive in [Pr. PX25].
