U/f
boost
(2.6.15.5)
Boost voltage at Frequency Limit to increase flux and torque. See chapter 6.2.
633
CL: Start-up torque, forward
(2.6.14.12)
Sets the start-up torque for forward direction if selected with P ID621.
634
CL: Start-up torque, reverse
(2.6.14.13)
Sets the start-up torque for reverse direction if selected with P ID621.
635
AOL: Frequency limit
(2.6.15.4)
Corner frequency for transition to standard U/f control. The value is given in % of motor
nominal frequency. See chapter 6.2.

Measured voltage drop
(2.6.5.18)
The measured voltage drop at stator resistance between two phases with the nominal
current of the motor. This parameter is identified durin ID run. Adjust this value to gain
optimum torque calculation for open loop low frequencies.
664
Ir: Add zero point voltage
(2.6.5.20)
Defines how much voltage is applied to motor in zero speed when torque boost is used.
665
Ir: Add generator scale
(2.6.5.21)
Defines scaling factor for generator side IR-compensation when torque boost is used
667
Ir: Add motoring scale
(2.6.5.22)
Defines scaling factor for motoring side IR-compensation when torque boost is used
