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]. Refer to the
"Name and
function" column.

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) in this section for details. 0h

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]. 0h

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].
