Torque Current Limitation [95]; Dc Link Regulator [96] - WEG CFW-11 Programming Manual

21.7.4 Torque Current Limitation [95]

P0169 – Maximum "+" Torque Current
P0170 – Maximum "-" Torque Current
Adjustable 0.0 to 350.0 %

Description:
These parameters limit the value of the motor current component that produces positive torque (P0169) and
negative torque (P0170). The setting is expressed in percentage of the motor rated current (P0401).
In case that any Analog Input (AIx) is programmed for the option 2 (Maximum Torque Current), P0169 and P0170
become inactive and the current limitation will be given by the AIx. In this case, the limitation value can be monitored
at the parameter correspondent to the programmed AIx (P0018 ... P0021).
In the torque limitation condition the motor current can be calculated by:
P 0169 or P0170
(*)
x P0401

motor
The maximum torque developed by the motor is given by:
T (%) = P0169 or P0170
motor
(*) If the current limitation is provided by an analog input, replace P0169 or P0170 by P0018, P0019, P0020 or P0021,
according to the programmed AIx. For more details, refer to the
NOTE!
Parameters P0171, P0172 and P0173 are inactive.

21.7.5 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 DC link overvoltage (F022) inverter tripping.
