11.3 b: Application
Figure 11.23 Example of Setting the Frequency Reference with a Current Signal to Terminal A2
Note:
Use this diagram also when wiring terminals A1 and A3.
Switching between master/auxiliary frequency references
The user can switch frequency reference input between terminals A1, A2, and A3 using the multi-step speed
reference function.
2 : Memobus/Modbus Communications
Enter the frequency reference by using MEMOBUS/Modbus communications.
3 : Option PCB
Use a communications option card or input option card connected to the drive to enter the frequency reference.
Refer to the instruction manual included with the option card for installing and setting the option card.
Note:
If b1-01 = 3 is set and an option card is not connected, then 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 RP to enter the frequency reference.
Follow the procedure below to make sure that the pulse train signal is functioning properly.
1. Set b1-01 = 4, H6-01 = 0 [PulseTrain InTerm RP Func Select = Frequency reference].
2. Set H6-02 [Pulse Train Input Scaling] to the number of pulses that determine 100% of the frequency
reference.
3. Enter a pulse train signal on the terminal RP and make sure that the keypad shows a correct frequency
reference.

b1-16 Run Command
Selection 2
(01C5)
Enabled when H1-xx = 2 [MFDI Function Select = External Reference 1/2 Selection] is set and switched ON.
0 : Keypad
Use the keypad to enter the Run command.
The user can execute the JOG operation or the FWD/REV commands from the keypad.
Note:
The LO/RE light will light when the Run command source is set to the keypad.
1 : Analog Input
Use the control circuit terminals to enter the Run command. Input method for the Run command is determined by
the sequence.
• 2-wire Sequence 1
This sequence allows for two types of input: FWD/Stop and REV/Stop. Setting A1-03 = 2220 [Initialize
Parameters = 2-Wire initialization] and initializing the drive sets terminals S1 and S2 for a 2-wire sequence.

V/f CL-V/f OLV CLV AOLV
Sets the input method for Run Command 2 when changing the source of the
Run command by switching the control circuit terminals ON/OFF.
