Setting 0: Disabled
Speed Control will be active. Also use this setting when H1-

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.

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.
