Vibration tough drive
Vibration tough drive function is a function to instantaneously reset the machine resonance suppression filter, and to prevent
vibration when machine resonance occurs due to the oscillation during adjustment and aging of the machine. By using this
function, the equipment continues to operate normally even when an alarm occurs. When continuing operation is required
even with an aging machine, the use of this function is recommended.
Vibration tough drive restrictions
The vibration tough drive function does not detect a vibration of 100 Hz or less.
Vibration tough drive can be used in the following cases.
When [Pr. PA20.1 Vibration tough drive selection] is set to "1" (Machine resonance
suppression filter change mode)
• When machine resonance suppression filter 1 is manually set, and the detected machine resonance frequency is within the
±30 % range of the set value for [Pr. PB13 Machine resonance suppression filter 1]
• When machine resonance suppression filter 2 is enabled, and the detected machine resonance frequency is within the ±30
% range of the set value for [Pr. PB15 Machine resonance suppression filter 2]
When [Pr. PA20.1 Vibration tough drive selection] is set to "2" (Machine resonance
suppression filter automatic setting mode)
• When [Pr. PB01.0 Filter tuning mode selection] is set to "0" (disabled), and machine resonance suppression filter 1 has
been disabled
• When [Pr. PB16.0 Machine resonance suppression filter 2 selection] is set to "0" (disabled), and machine resonance
suppression filter 2 has been disabled
• When machine resonance suppression filter 1 is manually set, and the detected machine resonance frequency is within the
±30 % range of the set value for [Pr. PB13 Machine resonance suppression filter 1]
• When machine resonance suppression filter 2 is enabled, and the detected machine resonance frequency is within the ±30
% range of the set value for [Pr. PB15 Machine resonance suppression filter 2]
Vibration tough drive precautions
• Resetting [Pr. PB13] and [Pr. PB15] by the vibration tough drive function is performed constantly. However, the number of
write times to the non-volatile memory is limited to once per five minutes.
• In vibration tough drive function, [Pr. PB46 Machine resonance suppression filter 3], [Pr. PB48 Machine resonance
suppression filter 4], and [Pr. PB50 Machine resonance suppression filter 5] are not reset.
Vibration tough drive setting method
Setting [Pr. PA20.1 Vibration tough drive selection] to "1" (Machine resonance suppression filter change mode) or "2"
(Machine resonance suppression filter automatic setting mode) causes [Pr. PB13 Machine resonance suppression filter 1]
and [Pr. PB15 Machine resonance suppression filter 1] to be automatically set when the oscillation level set in [Pr. PF23
Vibration tough drive oscillation detection level] is exceeded. This will suppress the vibration of the equipment.

Vibration tough drive selection
0: Disabled
1: Machine resonance suppression filter change mode
2: Machine resonance suppression filter automatic setting mode
When using the vibration tough drive, it is recommended to use "2" (Machine resonance suppression filter automatic setting
mode). When compatibility with MR-J4 is required, use "1" (machine resonance suppression filter change mode).
