2731 (FS15i)
Disturbance elimination filter gain (Kd)
2318 (FS30i, 16i)
[Valid data range] 101 to 500
[Typical setting] 500
NOTE
If a gain of 0 to 100 is set, the disturbance
elimination filter function does not operate.
2732 (FS15i)
Inertia ratio (Rj) (%)
2319 (FS30i, 16i)
[Valid data range] 0 to 32767
[Typical setting] 100
Set an inertia ratio (= machine inertia/motor inertia) in %.
Usually, set 100%.
2733 (FS15i)
Inverse function gain (Jmo)
2320 (FS30i, 16i)
[Valid data range] 100 to 2000
[Initial setting] 100 (Increase the setting step by step.)
Set an inverse function gain as a conversion coefficient for
acceleration-to-TCMD conversion. This parameter needs to be
adjusted. As a guideline, set a value not greater than the value
obtained by the following expressions:
Linear motor (The detection unit of the scale is assumed to be p µm.)
Jmo = 466048×p×Jm/Kt/Imax
Rotary motor
Jmo = 1396264×Jm/Kt/Imax
Jm: Weight [kg] or inertia [kgm
2
]
Kt: Torque constant [N/Ap] or [Nm/Ap]
Imax: Maximum amplifier current [Ap]
2734 (FS15i)
Filter time constant (Tp)
2321 (FS30i, 16i)
• When HRV1, HRV2, or HRV3 is used:
[Valid data range] 0 to 4096
[Typical setting] 3700 (equivalent to T = 10 ms).
* Usually, this value does not need to be changed.
Set a filter time constant for determining an estimated disturbance
velocity by using the following expression:
Tp = 4096 × exp (-t/T)
T: Setting time constant [sec], t = 0.001 [sec]
• When HRV4 is used:
[Valid data range] 0 to 4096
[Typical setting] 3994 (equivalent to T = 10 ms).
* Usually, this value does not need to be changed.
Set a filter time constant for determining an estimated disturbance
velocity by using the following expression:
Tp = 4096 × exp (-t/T)
T: Setting time constant [sec], t = 0.00025 [sec]
