PA20 Alarms may not be avoided with the tough drive function depending on the situations of the power supply and load
fluctuation.
*TDS
You can assign MTTR (During tough drive) to pins CN1-23, CN1-24, and CN1-49 with [Pr. PD24], [Pr. PD25], and [Pr.
Tough drive
PD28].
setting
_ _ _ x For manufacturer setting
_ _ x _ 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 exceed 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].
Refer to section 7.3 for details.
_ x _ _ SEMI-F47 function selection (instantaneous power failure tough drive selection)
0: Disabled
1: Enabled
Selecting "1" enables to avoid occurring [AL. 10 Undervoltage] using the electrical
energy charged in the capacitor in the servo amplifier in case that an instantaneous
power failure occurs during operation. In [Pr. PF25 SEMI-F47 function -
Instantaneous power failure detection time (instantaneous power failure tough drive -
detection time)], set the time until the occurrence of [AL. 10.1 Voltage drop in the
power].
When the parameter is enabled, the power should be off for the setting value of [Pr.
PF25] + 1.5 s or more before cycling the power to enable a parameter whose symbol
is preceded by "*".
