Dc Link Regulator [96] - WEG CFW-11 Programming Manual

Vector Control
Description:
Torque current limitation in function of the speed:
This function stays inactive when the contents of P0171/P0172 are higher or equal to the contents of P0169/
P0170.
P0171 and P0172 do also act during optimal braking limiting the maximum output current.
P0173 – Maximum torque curve type
Adjustable

Description:
It defines how the actuation of the torque limitation curve will be at the field weakening region. Refer to the figure
11.5.

11.8.7 Dc Link Regulator [96]

For the deceleration of high inertia loads with short deceleration times, the CFW-11 has available the DC Link
Regulation function, which avoids the tripping of the inverter by overvoltage in the DC link (F022).
