11.5 d: Reference Settings
Eliminates oscillation resulting from an unstable torque reference signal by applying a primary delay filter to the
torque reference signal. It is effective when removing noise from the torque reference signal, and when adjusting
the responsiveness between host controllers.
Increase the setting value when oscillation occurs during Torque Control. However, if the setting value is too high,
responsiveness becomes poor.

Selection
(029C)
1 : Active frequency reference
The enabled frequency reference set in b1-01 [Frequency Reference Selection 1] or b1-15 [Frequency Reference
Selection 2] will be the speed limit. Values set in C1-01 to C1-08 [Acceleration/Deceleration Times 1 - 4] and C2-
01 to C2-04 [S-Curve Time @ start/end of Accel] are applied as speed limits.
2 : d5-04 setting
The speed limit is the value set in d5-04.
■
d5-04: Speed Limit
No.
Name
(Hex.)
d5-04 Speed Limit
(029D)
The speed limit is + setting when it is in the same direction as the Run command. The speed limit is - setting when
it is in the opposite direction as the Run command.

d5-05: Speed Limit Bias
No.

(Hex.)
d5-05 Speed Limit Bias
(029E)
Used to adjust the margin for the speed limit.

d5-06: Speed/Torque Changeover Time
No.
Name
(Hex.)
d5-06 Speed/Torque
Changeover Time
(029F)
The analog input (torque reference, speed limit value) holds at the value present at the time of Speed/Torque
Control switchover within the time of the Speed/Torque Changeover Timer. During this time, complete the
preparations for switchover with an external source.

V/f CL-V/f OLV CLV AOLV
Selects the speed limit method associated with torque control.
V/f CL-V/f OLV CLV AOLV
Sets the speed limit during Torque Control as a percentage of the Maximum
Output Frequency. This parameter is effective when d5-03 = 2 [Speed Limit
Selection = d5-04 setting].
V/f CL-V/f OLV CLV AOLV
Sets a bias to the speed limit value as a percentage of E1-04 [Maximum
Output Frequency].
V/f CL-V/f OLV CLV AOLV
Sets the delay time for switching between Speed Control and Torque
Control using the multi-function digital input terminal. This parameter is
effective when H1-xx = 71 [MFDI Function Select = Speed/Torque Control
Switch] has been set.
V/f CL-V/f OLV CLV AOLV
Selects the direction of the speed limit reference to which Speed Limit Bias
[d5-05] applies.
