No. Name and function
25 Low-pass filter/adaptive vibration suppression control
Used to select the low-pass filter/adaptive vibration
suppression control.
0
Low-pass filter selection
0: Available (Automatic adjustment)
1: Disabled
When available is selected, the filter in
the zone expressed by the following
formula is automatically set.
For 1 kW or less
VG2 setting value × 10
2π × (1 + GD2 setting value × 0.1)
For 2 kW or more
VG2 setting value × 5
2π × (1 + GD2 setting value × 0.1)
Adaptive vibration suppression control
selection
0: Disabled
1: Enabled
Usually, machine resonance
frequency is detected, and a filter
corresponding to the resonance is
generated to control the machine
vibration.
2: Maintenance
Until then, detection of machine
resonance is stopped by keeping the
characteristics of the filter generated
until that moment.
Adaptive vibration suppression control
selection
Set the sensitiveness to detect the
machine resonance.
0: Normal
1: High sensitive
27 Analog monitor 1 offset
Used to set the offset voltage of Analog monitor 1 (MO1)
output.
28 Analog monitor 2 offset
Used to set the offset voltage of Analog monitor 2 (MO2).
30 Zero speed
Used to set the output range of zero speed signal (ZSP).
31 Error excessive alarm level
Used to set the range where the excess droop pulse alarm
is generated.
Note: The setting unit for servo amplifier of software version
B1 or later is 0.025 rev. Note: The setting unit for
servo amplifier before software version B1 is 0.1 rev.

0 PC11 Analog monitor 1 offset
Used to set the offset voltage of MO1 (Analog monitor 1).
0 PC12 Analog monitor 2 offset
Used to set the offset voltage of MO2 (Analog monitor 2).
50 PC07 Zero speed
Used to set the output range of ZSP (Zero speed
detection).
ZSP (Zero speed detection) has the hysteresis of 20
[r/min] or 20 [mm/s]
80 PC01 Error excessive alarm level
Set error excessive alarm level.
The setting unit for rotary servo motor is "rev". If "0" is set,
it becomes 3 rev. The setting value exceeding 200 rev will
be clamped at 200 rev.
PC06 Function selection C-3
Used to select the setting unit for error excessive alarm
level to be set in [Pr. PC01]. This parameter cannot be
used in the speed control mode and torque control mode.
