Parameters for Adjustment (2nd Gain Switching Function)

PrNo. Title

214
Setup
Unit
range
0 to 2000 0.1Hz You can set up the 1st damping frequency of the damping control which
suppress vibration at the load edge.
<0>
The driver measures vibration at load edge. Setup unit is 0.1[Hz].
The setup frequency is 10.0 to 200.0[Hz]. Setup of 0 to 99 becomes invalid.
Refer to P.250, "Damping control" as well before using this parameter.
–200 to 2000 0.1Hz While you set up Pr2B (1st damping frequency), set this up to smaller
value when torque saturation occurs, and to larger value when you need
<0>
faster action.Use with the setup of 0 in normal operation. Refer to P.250,
"Damping control" of Adjustment.
<Caution>
Setup is also limited by 10.0[Hz]–Pr2B
0 to 2000 0.1Hz You can set up the 2nd damping frequency of the damping control which
suppress vibration at the load edge.
<0>
The driver measures vibration at the load edge. Setup unit is 0.1 [Hz].
Setup frequency is 10.0 to 200.0 [Hz]. Setup of 0 to 99 becomes invalid.
Refer to P.250, "Damping control" of Adjustment as well before using this
parameter.
–200 to 2000 0.1Hz While you set up Pr2D (2nd damping frequency), set this up to smaller
value when torque saturation occurs, and to larger value when you need
<0>
faster action.
Use with the setup of 0 in normal operation. Refer to P.250, "Damping
control" of Adjustment.
<Caution>
Setup is also limited by 10.0[Hz]–Pr2D
0 to 64 – Displays the table No. corresponding to the adaptive filter frequency.
(Refer to P.234 of Adjustment.) This parameter will be automatically set
<0>
and cannot be changed while the adaptive filter is valid. (when Pr23
(Setup of adaptive filter mode) is other than 0.)
0 to 4
5 to 48 Filter is valid.
49 to 64 Filter validity changes according to Pr22.
This parameter will be saved to EEPROM every 30 minutes while the
adaptive filter is valid, and when the adaptive filter is valid at the next
power-on, the adaptive action starts taking the saved data in EEPROM as
an initial value.
<Caution>
When you need to clear this parameter to reset the adaptive action while
the action is not normal, invalidate the adaptive filter (Pr23, "Setup of
adaptive filter mode" to 0) once, then validate again.
Refer to P.239,
Adjustment as well.
