u External Reference Selection and Acceleration/Deceleration Times
n b1-01: Frequency Reference Selection
Set parameter b1-01 according to the frequency reference used.
b1-01 Reference Source Frequency Reference Input
0 Digital operator
Set the frequency references in the d1-oo parameters and use digital inputs to switch over between
different reference values.
1 Analog input terminals Apply the frequency reference signal to terminal A1, A2, or A3.

communications
Serial Communications using the RS422/485 port
3 Option PCB Communications option card
4 Pulse input (terminal RP) Set the frequency reference at terminal RP using a pulse train signal.
n b1-02: Run Command Selection
Set parameter b1-02 according to the Run command used.
b1-02 Reference Source Run Command Input
0 Digital operator RUN and STOP keys on the operator
1 Digital input terminals Multi-Function digital input

n Acceleration/ Deceleration Times and S-Curves
There are two sets of acceleration and deceleration times which can be set in the C1-oo parameters. The default activated
accel/decel times are C1-01/C1-02. Adjust these times to the appropriate values required by the application. If necessary, S-
curves can be activated in the C2-oo parameters for softer accel/decel start and end.
u Reference and Run Source
The drive has a LOCAL and a REMOTE mode.
Status Description
LOCAL The Run/Stop command and the frequency reference are entered at the operator keypad.
REMOTE The Run command source entered in parameter b1-02 and the frequency reference source entered in parameter b1-01 are used.
If the drive is operated in the REMOTE mode, make sure that the correct sources for the frequency reference and run command
are set in parameters b1-01/b1-02 and that the drive is in the REMOTE mode.
The LED in the LO/RE key indicates where the Run command is input from.
LO/RE LED Description
ON Run command is issued from operator.
OFF Run command is issued from a different source than the operator.
u I/O Setup
The default setting functions can be seen in the connection diagram on page 19 .
n Multi-Function Digital Inputs (H1-oo)
The function of each digital input can be assigned in the H1-oo parameters.
n Multi-Function Digital Outputs (H2-oo)
The function of each digital output can be assigned in the H2-oo parameters. The setting value of these parameters consist
of 3 digits, where the middle and right digit set the function and the left digit sets the output characteristics (0: Output as
selected; 1: Inverse output).
