Figure 5.2 Setting the Frequency Reference as a Current Signal to Terminal A2
DIP switch S1 must first be set for current input.
Switching between Main/Auxiliary Frequency References
The frequency reference input can be switched between the analog terminals A1, A2, and A3 using multi-speed inputs.
Refer to
Multi-Step Speed Selection on page 231
for details on using this function.
Setting 2: MEMOBUS/Modbus Communications
This setting requires entering the frequency reference via the RS-485/422 serial communications port (control terminals
R+, R-, S+, and S-). Refer to
MEMOBUS/Modbus Communications on page 557
for instructions.
Setting 3: Option card
This setting requires entering the frequency reference via an option board plugged into connector CN5-A on the drive
control board. Consult the option board manual for instructions on integrating the drive with the communication system.
Note:
If the frequency reference source is set for an option PCB (b1-01 = 3), but an option board is not installed, an oPE05 operation
error will be displayed on the digital operator and the drive will not run.
Setting 4: Pulse Train Input
When b1-01 is set to 4, the frequency reference must be provided by a pulse train signal to terminal RP. Follow the
directions below to make sure the pulse train signal is working properly.
Verifying Pulse Train is Working Properly
• Make sure that b1-01 is set to 4 and H6-01 is set to 0.
• Set the pulse input scaling H6-02 to the pulse train frequency value that equals 100% of the frequency reference.
• Enter a pulse train signal to terminal RP and check if the correct frequency reference is displayed.

b1-02: Run Command Selection 1
Parameter b1-02 determines the Run command source 1 in the REMOTE mode.
Setting 0: Operator
This setting requires entering the Run command via the digital operator RUN key and also illuminates the LO/RE
indicator on the digital operator.
Setting 1: Control Circuit Terminal
This setting requires that the Run and Stop commands are entered from the digital input terminals. The following
sequences can be used:
• 2-wire sequence 1:
Setting A1-03 to 2220 initializes the drive and presets terminals S1 and S2 to FWD/Stop and REV/Stop. These are the
default settings of the drive. Refer to
Setting 40, 41: Forward run, Reverse run command for 2-wire sequence on
• 2-wire sequence 2:
Two inputs (Start/Stop-FWD/REV). Also refer to
Setting 42, 43: Run and direction command for 2-wire sequence 2
.
No.
