Required settings:
Notes:
•
When the Forward Run and Reverse Run
commands are active at the same time, the inverter
enters the Stop Mode.
•
When a terminal associated with either [FW] or
[RV] function is configured for normally closed,
the motor starts rotation when that terminal is
disconnected or otherwise has no input voltage.

Using Intelligent Input Terminals

Terminals 1, 2, 3, 4, and 5 are identical,
programmable inputs for general use. The
input circuits can use the inverter's internal
(isolated) +24V field supply (P24) to power
the inputs. The input circuits are internally
connected to the power supply ground. As the
diagram shows, you can use a switch (or
jumper) to activate an input terminal which
has been programmed. If you use an external
supply, its GND terminal must connect to the
"L" terminal on the inverter to complete the
input circuit. We recommend using the top
row "L" logic GND for login input circuits
and the "L" GND on the bottom row of termi-
nals for analog I/O circuits.
When you input the Run command via the terminal [FW], the inverter executes the
Forward Run command (high) or Stop command (low). When you input the Run
command via the terminal [RV], the inverter executes the Reverse Run command (high)
or Stop command (low).

WARNING: If the power is turned on and the Run command is already active, the motor
starts rotation and is dangerous! Before turning power on, confirm that the Run
command is not active.
