Figure 6-33 Double-speed over-current stall action diagram
Note:
1. Over-current stall action current 180% means 1.8 times of the rated current of inverter;
2. For high-power motors with carrier frequency below 2 kHz, due to the increasing of the pulse current, the
wave-by-wave current-limit response starts before the over-current stall action, and the torque is
insufficient. In this case, reduce the over-current stall action current.

PID adjustment is too slow in some applications, adjust this parameter, PID output value = the original PID
output value * this parameter.

If the field needs 4mA ~ 20mA analog output, the corresponding signal source for AO1, AO2 output analog
signal (A9-09, A9-10) need to be selected, no need to set the zero-offset coefficient (P5-10
、
P5-12). The
analog output deviation is corrected by the corresponding P5-11 and P5-13 gains.
