NOTE: Intelligent terminals [OPE] (option code 31) or [F-TM] (option code 51) can override
settings A001 and A002 when either terminal is ON and the operation commands for that
terminal is enabled.
NOTE: When using a remote operator (SRW) to operate the inverter, the REMT (remote) key
allows you to enter the frequency setting and operation commands remotely.
NOTE: When the DeviceNet option board (SJ-DN) is installed, you may keep the A002
default setting because the Run Command Source is automatically set via DeviceNet. Other-
wise, only use settings A002 = 01, 02, or 03.
NOTE: The base frequency must be less than or equal to the maximum frequency (ensure that
A003 ≤ A004).
The inverter has the capability to accept external analog inputs that can command the output
frequency to the motor. Signals including voltage input (0 to +10V) at terminal [O], bipolar
input (-10 to +10V) at terminal [O2], and current input (4 to 20mA) at terminal [OI] are avail-
able. Terminal [L] serves as signal ground for the three analog inputs. The analog input settings
adjust the curve characteristics between the analog input and the frequency output.
Adjusting [O–L] characteristics – In the
graph to the right, A013 and A014 select
the active portion of the input voltage
range. Parameters A011 and A012 select
the start and end frequency of the
converted output frequency range, respec-
tively. Together, these four parameters
define the major line segment as shown.
When the line does not begin at the origin
(A011 and A013 > 0), then A015 defines
whether the inverter outputs 0Hz or the
A011-specified frequency when the
analog input value is less than the A013
setting. When the input voltage is greater
than the A014 ending value, the inverter
outputs the ending frequency specified by
A012.
