0 Operator Digital Operator
1 Terminals Control circuit terminals (analog inputs)
2 Serial Com Not used. (Do not set.)
3 Option PCB Optional
Card (CompoBus/D Communications
Card, SYSMAC BUS I/F Card,
Analog Command Card, or Digital Command Card)
4 EWS Not used. (Do not set.)
Note 1. The
frequency reference is input
from the control circuit terminals (external terminals), so set
b1-01 to 1.
Note 2. The
source specified for the frequence
reference is used as frequency reference 1 in multi
-
stage
control. If the frequence reference source is set to a control terminal,
the frequence ref
-
erence analog input from the control terminal will take priority and the frequency for d1-01 will
be
ignored. (The frequency for d1-01 will be used, however
, if operation is switched to local
mode using the operation mode selection key.)
Note 3. Regardless
of the frequency source, the values set for frequency reference parameters 2 to 8
(d1-02 to d1-08) and the inching frequency reference parameter (d1-09) will be enabled.
H Frequency Reference: Terminal 13 Voltage Input (H3-01)
The
frequency
reference (voltage) is valid when parameter b1-01 has been set to 1. Parameter H3-01 is
used to set the voltage range for the frequency reference (voltage) signal. This parameter cannot be
changed during operation.

(A negative voltage is a command for rotation in the opposite direction.)
H Frequency Reference: Terminal 14 Current Input (H3-08 and H3-09)
Terminal
14 must be set to “frequency reference” with
parameter H3-09 in order to use terminal 14 as
the
frequency reference terminal; the “frequency reference” setting is 1F
. Neither H3-08 nor H3-09 can
be changed during operation.
