7.2 Torque control with speed limitation
Purpose
The drive is changed to torque control by the setting the configuration to C005 =
-4X- ”torque control with speed limitation”. The torque can be entered in both
directions.
In different operating modes, the speed is monitored with a speed limitation by
means of the n-controller.
Parameter setting
Stop!
With a negative torque set-value , the speed limitation is not effective. The drive can
reach impermissibly an impermissibly high speed, which can damage motor or
machine. These applications can only be monitored with the digital ouput
act

.
For standard applications, the drive can be immediately commissioned with the
default settings. To adapt it to special requirements, please observe the notes in
chapter 7.1, ”speed-controlled operation”.
Set-value Terminal Parameter setting with
speed set-value X1/8 C025 = -4-
Additional set-value X1/6 C025 = -3-
External torque selection M

X1/1, 2 C025 = -1-
The speed set-value and the additional set-value are selected as bipolar values via
X1/8 or X1/6. The direction of rotation results from the sign of the linkage between
main and additional set-value and the selection made at X2/21 und X2/22.
