P03.21 sets P03.19)
1: Set via AI1 (100% relative to three times of
motor current)
2: Set via AI2 (same as above)
3: Set via AI3 (same as above)
4: Set via HDI (same as above)
5: Set via MODBUS communication (same as
above)
6 – 8: Reserved
Note: Setting mode 1 – 8, 100% corresponds to
three times of the motor current.
The function code is used to set the limit of the
torque.
Setting range: 0.0 – 300.0% (motor rated
current)
The usage of motor in flux weakening control.
Function code P03.22 and P03.23 are effective
at constant power. The motor will enter the flux
weakening state when running at rated speed.
Change the flux weakening curve by modifying
the flux weakening control coefficient. The bigger
the flux weakening control coefficient is, the
steeper the weakening curve is.

Questions and answers
Start stop time
The start-stop time for the INVT Goodrive20-EU VFD Series is not explicitly mentioned in the provided context. However, the "Pre-exciting time" (P03.25) is listed as a parameter that helps improve torque performance during startup, with a setting range of 0.000 to 10.000 seconds. If more specific start-stop time details are needed, they may be found in additional documentation.
