Figure 12.7 Example of Setting the Frequency Reference with a Voltage Signal to Terminal AI1
Note:
You can also use this diagram to wire terminal AI2.
• Current Input
Refer to Table 12.7 to use a current signal input to one of the MFAI terminals.
Terminal Signal Level
A2 4 - 20 mA
0 - 20 mA
Figure 12.8 Example of Setting the Frequency Reference with a Current Signal to Terminal AI2
Changing between Master and Auxiliary Frequency References
Use the multi-step speed reference function to change the frequency reference input between terminals AI1 and
AI2.
2 : Modbus
Use Modbus communications to enter the frequency reference.
3 : Option PCB
Use a communications option connected to the drive to enter the Run command.
Refer to the instruction manual included with the option to install and set the option.
Note:
If b1-01 = 3 but you did not connect an option, oPE05 [Run Cmd/Freq Ref Source Sel Err] will flash on the keypad.
4 : Pulse Train Input
Use a pulse train signal from the pulse train input terminal PI to enter the frequency reference.
Do this procedure to make sure that the pulse train signal is operating correctly.
1. Set b1-01 = 4, H6-01 = 0 [PI Pulse Train Function = Freq Ref].
