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 74
Setting 2: MEMOBUS/Modbus Communications
This setting requires that the frequency reference is entered via the RS-485/422 serial communications port (control
terminals R+, R-, S+, S-).
Setting 3: Option card
This setting requires that the frequency reference is entered via an option board plugged into connector CN5-A on the
drives control board. Consult the manual supplied with the option board 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 Operator
Programming Error will be displayed on the digital operator and the drive will not run.
Setting 4: Pulse Train Input
If 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 signal is working properly.
Verifying Pulse Train is Working Properly
• Make sure that b1-04 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.
No.
b1-02
Setting 0: Operator
When the b1-02 = 0, the LO/RE light will switch on and the RUN key will enter a Run command to start the drive.
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:
Two inputs (FWD/Stop-REV/Stop). Initializing the drive by setting A1-03 = 2220, presets the terminals S1 and S2 to
these functions. This is the default setting of the drive.
• 2-wire sequence 2:
Two inputs (Start/Stop-FWD/REV).
• 3-wire sequence:
Three inputs (Start-Stop-FWD/REV). Initialize the drive by setting A1-03 = 3330 presets the terminals S1, S2, and S5
to these functions. Also refer to
Setting 2: MEMOBUS/Modbus Communications
To issue a Run command via serial communications, set b1-02 to 2 and connect the RS-485/422 serial communication
cable to control terminals R+, R-, S+, and S- on the removable terminal block.
Setting 3: Option Card
To issue the Run command via the communication option board, set b1-02 to 3 and plug a communication option board
into the CN5-A port on the control PCB. Refer to the manual supplied with the option board for instructions on
integrating the drive into the communication system.
Note: If b1-02 is set to 3, but an option board is not installed in CN5-A, an oPE05 operator programming error will be displayed on the
digital operator and the drive will not run.
