The inverter operation/stop command and frequency command can be control by the built-in PLC of
inverter. At this time, the set values of 00-05 are invalid.

(1) 00-05= 0:
. Use the digital operator (as shown in Figure 4.3.4) to directly input frequency
reference command, or to change parameters of 05-01 (frequency reference 1)
settings. Please refer to section 4.1.4, the screen mode - details of setting the
frequency reference.
(2) 00-05=1:
. From the control circuit terminal AI1 (voltage input) or AI2 (current input, set by
04-00), input the frequency reference command.
. When the input voltage signal acts as the main frequency reference command, use
AI1 terminal.
. When the input current signal (4-20mA) acts as the main frequency reference
command, use AI2 terminal, setting steps are shown as below:
1 Input 0V to terminal AI1
2 Set 04-00=1: (select the multi-function analog input terminal AI2 signal as the
input of 4 ~ 20mA)
3 Set the dip switch SW2 to position I (current).
4 Set 04-05=10 (AI2 signal is increased to AI1).
. Refer to Figure 4.3.4 so understand the source selection of main speed frequency
comes from details of analog terminals setting.
