The reference frequency is set by analog input. CHE series inverter provides 2 analog
input terminals. AI1 is 0~10V voltage input terminal, while AI2 is 0~10V voltage input or
0~20mA current input. Voltage input or current input of AI2 can be selected by Jumper
J16.
Notice:
z When AI2 is set as 0~20mA current input, the corresponding voltage range is
0~5V. For detailed relationship between analogue input voltage and frequency,
please refer to description of P5.07~P5.11.
z 100% of AI is corresponding to maximum frequency(P0.04)
4: Multi-step speed
The reference frequency is determined by PA group. The selection of steps is determined
by combination of multi-step speed terminals.
Notice:
z Multi-step speed mode will enjoy priority in setting reference frequency if
P0.03 is not set to be 4. In this case, only step 1 to step 15 are available.
z If P0.03 is set to be 4, step 0 to step 15 can be realized.
Jog has highest priority.
5: PID
The reference frequency is the result of PID adjustment. For details, please refer to
description of P9 group
6: Communication
The reference frequency is set through RS485. For details, please refer to description of
Chapter 10.
