Upper-limit
setting of
electromotion
torque
This function code is used to select the electromotion
and braking torque upper-limit setting source selection.
0: Keypad setting upper-limit frequency (P03.20 sets
P03.18 and P03.21 sets P03.19)
1: Analog AI1 setting upper-limit torque
2: Analog AI2 setting upper-limit torque
3: Analog AI3 setting upper-limit torque
4: Pulse frequency HDI setting upper-limit torque
5: MODBUS communication setting upper-limit torque
6–8: Reserved
Note: Setting mode 1–8, 100% corresponds to three
times of the motor current.

Weakening
coefficient in
constant
power zone
The usage of motor in weakening control.
Function code P03.22 and P03.23 are effective at
constant power. The motor will enter into the weakening
state when the motor runs at rated speed. Change the
weakening curve by modifying the weakening control
coefficient. The bigger the weakening control coefficient
is, the steeper the weak curve is.
Setting range of P03.22: 0.1–2.0
Setting range of P03.23: 10%–100%
