Code Description
Cn.20 SL2 G View Sel
Setting Function
0 No Does not display sensorless (II) vector control gain code.
1 Yes Allows the user to set various gains applied when the
motor rotates faster than medium speed (approx. 1/2 of
the base frequency) through sensorless (II) vector
control.
Codes available when setting to 1 (Yes): Cn.23 ASR-SL P Gain2/Cn.24
ASR-SL I Gain2/Cn.26 Flux P Gain/Cn.27 Flux I Gain Gain3/Cn.28 S-Est P
Gain1/Cn.29 S-Est I Gain1/Cn.30 S-Est I Gain1/Cn.31 ACR SL P Gain/Cn.32
ACR SL I Gain
Cn.23 ASR-SL P Gain2,
Cn.24 ASR-SL I Gain2 Speed Controller P Gain2 and I Gain2 appear only when Cn.20 (SL2 G
view Sel) is set to 1 (Yes). The overall speed controller gain can be
increased to more than the medium speed for sensorless vector control.
Cn.23 ASR-SL P Gain2 is set as a percentage of the low speed gain Cn.21
ASR-SL P Gain1 - if P Gain 2 is less than 100.0%, the responsiveness
decreases. For example, if Cn.21 ASR-SL P Gain1 is 50.0% and Cn.23 ASR-
SL P Gain2 is 50.0%, the actual middle speed or faster speed controller P
gain is 25.0%.
Cn.24 ASR-SL I Gain2 is set as a percentage of the Cn.22 ASR-SL I Gain1.
For I gain, the smaller the I gain 2 becomes, the slower the response time
becomes. For example, if Cn.22 ASR-SL I Gain1 is 100ms and Cn.24 ASR-
SL I Gain2 is 50.0%, the middle speed or faster speed controller I gain is
200 ms. The controller gain is set according to the default motor
parameters and Acc/Dec time.
Cn.26 Flux P Gain,
Cn.27 Flux I Gain,
Cn.85-87 Flux P Gain13,
Cn.88-90 Flux I Gain1-3
Rotor Flux Estimator P & I Gains. Sensorless vector control requires the
rotor flux estimator. For the adjustment of flux estimator gain, refer to
5.10.2
.
Cn.28 S-Est P Gain1,
Cn.29 S-Est I Gain1,
Cn.30 S-Est I Gain2 Speed Estimator P & I Gains. Speed estimator gain for sensorless vector
control can be adjusted. To adjust speed estimator gain, refer 5.10.2 .
Cn.31 ACR SL P Gain,
Cn.32 ACR SL I Gain Current Controller P & I Gains. Adjusts the current controller P and I
gains. For the adjustment of sensorless current controller gain, refer to
5.10.2
.
Cn.53 Torque Lmt Src Select a source for torque limit setting: keypad, analog input (V1 and I2)
or communication. When setting torque limit, adjust the torque size by
limiting the speed controller output. Set the retrograde (motoring) and
regenerative limits for forward and reverse operation.
Setting Function
0 KeyPad-1 Sets the torque limit with the
keypad.
