Iq lower limit DC link ctrl
Lower torque current limit in the regenerative direction in ampere executed by the DC link
controller.
114.7
Speed threshold for block shape current
If the Udc link-ld controller is switched on block-shaped ld current is supplied above this
threshold.
Below this threshold the current is increased only in order to reduce the braking energy.
Braking with block-shaped ld current can be switched off, if the value of the speed thresh-
old is set above the maximum speed.
114.8
Flux threshold
The flux is minimal with block-shaped ld current. If the actual flux drops below this thresh-
old the sign of the ld current is changed.
114.9
DC link voltage hysteresis
If the DC link voltage drops below the maximum value (
) by this value, the torque
current is no longer limited.
114.10
Factor maximum voltage for Id-brake
Factor for the threshold and set value of the reactive current brake. Therefore, the actual
Udc link set value for the reactive current brake results from the product of

114.11
Reactive current controller output
Output of the reactive current controller. It is located between 0 and 1 whereby 0 means
the maximum ld current and 1 means no ld current.
