P0136 – Manual Torque Boost
Adjustable
Range:
0 to 9
Factory
Setting:
According
to inverter
model
Properties:
V/f
Access groups
via HMI:
01 PARAMETER GROUPS
23 V/f Control
Description:
It acts at low speeds, increasing the inverter output voltage in order to compensate the voltage drop across the
motor stator resistance, with the purpose of keeping the torque constant.
The optimum setting is the lowest value of P0136 that allows a satisfactory starting of the motor. Values higher than
the necessary will increase the motor current at low speeds, being able to lead the inverter to a fault (F048, F051,
F071, F072, F078 or F183) or alarm (A046, A047, A050 or A110) condition.

NOTE!
For large frames than frame C, the standard value is 0. For others, the standard value is 1.
P0137 – Automatic Torque Boost
Adjustable
Range:
0.00 to 1.00
Factory
Setting:
0.00
Properties:
V/f
Access groups
via HMI:
01 PARAMETER GROUPS
23 V/f Control
Description:
The Automatic Torque Boost compensates the voltage drop on the stator resistance in function of the motor active
current.
The criteria for adjusting P0137 are the same as for the parameter P0136.
