Goodrive3000 series medium voltage VFD
Function
code
The function code is used to set the source of electromotive torque upper limit.
Note:
1. For setting sources 1–8, 100% corresponds to three times the rated motor current.
2. The options 3, 4, 6, and 7 are available only when corresponding expansion cards are configured.

Braking torque upper limit set
P03.21
The function code is used to set the torque upper limit via keypad.
Function
code
P03.22 coefficient in constant
Lowest weakening
P03.23
P03.22 is only valid for the vector mode 1 and closed-loop vector mode.
The function code is used when the motor is in flux-weakening control.
The function codes P03.22 and P03.23 are valid at constant power. The motor enters the flux-weakening state when the
motor runs above the rated speed. Change the flux-weakening curvature by modifying the flux-weakening control
coefficient. The larger the coefficient, the steeper the curve, the smaller the coefficient, the smoother the curve.

code
P03.24
P03.25
P03.26
P03.24: It sets the max. output voltage of the VFD. Set the value according to onsite conditions.
P03.25: Pre-exciting is performed for the motor when the VFD starts up. A magnetic field is built up inside the motor to
improve the torque performance during the start process.
