PX24 FRIC Machine diagnosis function - Friction judgment speed
Set a servo motor speed that divides a friction estimation area into high and low
during the friction estimation process of the machine diagnosis.
Setting "0" will set a value half of the rated speed.
When your operation pattern is under the rated speed, we recommend that you set
a half value of the maximum speed.

PX25 *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, CN3-13, and CN3-15
with [Pr. PD07] to [Pr. PD09].

Operation pattern
Explanation
For manufacturer setting
Vibration tough drive selection
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 (7) in this section for details.
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. 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].
