2. Set d5-01 to 0 when switching between Torque Control and Speed Control. An oPE15 alarm will be triggered if parameter d5-01 is
set to 1 while H1- is set to 71 at the same time.
Figure 5.51
Figure 5.51 Speed/Torque Control Switching Time
■ d5-01: Torque Control Selection
Setting 0: Disabled
Speed Control will be active. Also use this setting when H1- = 71 (Speed/Torque Control Switch).
Setting 1: Enabled
Torque Control is always enabled.
■
d5-02: Torque Reference Delay Time
A filter with the time constant set in parameter d5-02 can be applied to the torque reference signal in order to eliminate
oscillation that results from an unstable torque reference signal. A higher filter time will stabilize control, but also reduce
the responsiveness.
■
d5-03: Speed Limit Selection
Parameter d5-03 determines how the speed limit is set.
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: Parameter d5-04
The speed limit is set by parameter d5-04.
■
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 190.
