P0136 - Addition on the manual torque curve (IxR)
Adjustable range: 0 to 100 Factory setting: 0
Acesso: Menu → Configurations → Control
Description:
It compensates the voltage drop in the motor stator resistance.
It actuates at low speeds, increasing the inverter output voltage in order to keep the torque constant at V/F
operation.
The optimal setting is the smallest value of P0136 that allows the satisfactory motor start.
Value above the necessary will increment in excess the motor current at low speeds, which may force the
inverter in an overcurrent condition (F0070, F0071 and F0072).
The maximum value of increase for the output voltage is equal to 20 % of the rated voltage, in null frequency,
when P0136 = 100.
Setting 0 means inactive function.
