Terminal [X1] to [X3] Function
Terminal [FWD] and [REV] Function
Function codes E01 to E03, E98 and E99 allow you to assign commands to ter-
minals [X1] to [X3], [FWD], and [REV] which are general-purpose, programmable,
digital input terminals.
These function codes may also switch the logic system between normal and
negative to define how the inverter logic interprets either ON or OFF status of each
terminal. The default setting is normal logic system "Active ON."
To assign negative logic input to any input terminal, set the function code to the
value of 1000s shown in ( ) in Section 5.1 " Function Code Tables." To keep ex-
planations as simple as possible, the examples shown below are all written for the
normal logic system.
Select multi-frequency (1 to 7 steps)--SS1, SS2, and SS4
(Function code data = 0, 1, and 2)
The combination of the ON/OFF states of digital input signals SS1, SS2, and SS4
selects one of 8 different frequency commands defined beforehand by 7 function
codes C05 to C11 (Multi-frequency 0 to 7). With this, the inverter can drive the motor
at 16 different preset frequencies.
The table below lists the frequencies that can be obtained by the combination of
switching SS1, SS2, and SS4. In the "Selected frequency" column, "Other than
multi-frequency" represents the reference frequencies defined by frequency
command 1 (F01), frequency command 2 (C30), or others.

OFF OFF ON C05 (Multi-frequency 1)
OFF ON OFF C06 (Multi-frequency 2)
OFF ON ON C07 (Multi-frequency 3)
ON OFF OFF C08 (Multi-frequency 4)
ON OFF ON C09 (Multi-frequency 5)
ON ON OFF C10 (Multi-frequency 6)
ON ON ON C11 (Multi-frequency 7)
Select ACC/DEC time (2 steps)--RT1
(Function code data = 4)
Digital input signal RT1 assigned to the specified terminal on/off may switch com-
binations between acceleration/deceleration time 1 (defined by function codes F07
and F08) and acceleration/deceleration time 2 (defined by E10 and E11).
Turning RT1 on, for example, enables the inverter to drive the motor using accel-
eration/deceleration time 2.
