3.7.4.6 Description of the DC link controller Parameter
114.1 DC link controller set value
Maximum value for the DC link voltage.
During braking procedures, energy is fed back from the motor into the DC link, which is
further charged as a result.
On devices that do not have regenerative capability, the energy can only be dissipated
via a chopper resistor.
To prevent the DC link voltage from rising too far, it is limited to the maximum value set
here by means of a control arrangement. To this end, the deceleration torque in the drive
is reduced if necessary, so that the DC link voltage does not rise any further.
114.2 P-Gain of DC link controller
Proportional gain of the DC link controller, 
Units: 1/V.
The controller output of the DC link controller limits the permissible Iq current in the gen-
erator mode. Output = 0.5 means Iq should be a maximum of 0.5 * Z138.6– or Z138.7–.
114.3 Tn of DC link controller
Reset time of the DC link controller 
Units: ms
114.5 Iq upper limit DC link ctrl
Upper torque current limit in the regenerative direction in ampere executed by the DC link
controller.
