d5-01: Torque Control Selection
No. Parameter Name Setting Range Default
d5-01 Torque Control Selection 0, 1 0
Setting 0: Disabled
Speed Control will be active. Also use this setting when H1-oo = 71 (Speed/Torque Control Switch).
Setting 1: Enabled
Torque Control is always enabled.
n
d5-02: Torque Reference Delay Time
Apply a filter with the time constant set to parameter d5-02 to the torque reference signal to eliminate oscillation resulting
from an unstable torque reference signal. A higher filter time stabilizes control while reducing the responsiveness.
No. Parameter Name Setting Range Default
d5-02 Torque Reference Delay Time 0 to 1000 ms 0 ms
n
d5-03: Speed Limit Selection
Determines how the speed limit is set.
No. Parameter Name Setting Range Default
d5-03 Speed Limit Selection 1 or 2 1
Setting 1: Frequency Reference Input
The frequency reference value at the active reference source (digital operator, External reference 1 or External reference 2)
will be used as speed limit. Note that in this case all settings for accel/decel times (C1-01 to C1-08) and S-curves (C2-01 to
C2-04) will apply for the speed limit.
Setting 2: d5-04
The speed limit is set by parameter d5-04.
n
d5-04: Speed Limit
Sets the speed limit during torque control if parameter d5-03 is set to 2. Refer to Speed Limitation and Speed Limit Bias on
page 69.
No. Parameter Name Setting Range Default
d5-04 Speed Limit -120 to 120% 0%
n
d5-05: Speed Limit Bias
Applies a bias set as a percentage of the maximum output frequency to the speed limit value. Refer to Speed Limitation and
Speed Limit Bias on page 69.
