Input terminal function assignment
Function codes E01 and E02 is available for assigning function to DI1 and DI2.
- Run forward -- FWD (Function code data = 98) Turning this terminal command ON runs the motor in the
forward direction; turning it OFF decelerates it to stop.
- Run reverse -- REV (Function code data = 99) Turning this terminal command ON runs the motor in the
reverse direction; turning it OFF decelerates it to stop.

4.3.2
Output terminal function assignment
E7 assign output signals (listed on the next page) to general-purpose, programmable output terminals
[30A/B/C]. These function codes can also switch the logic system between normal and negative to define the
property of those output terminals so that the inverter logic can interpret either the ON or OFF status of each
terminal as active. The factory default settings are "Active ON."
Terminals [30A/B/C] are single-pole double-throw (Form C) relay outputs. In normal logic, if an alarm occurs,
the relay will be energized so that [30A] and [30C] will be closed, and [30B] and [30C] opened. In negative
logic, the relay will be de-energized so that [30A] and [30C] will be opened, and [30B] and [30C] closed. This
may be useful for the implementation of failsafe power systems.
➢
When a negative logic is employed, all output signals are active (e.g., an alarm would be recognized)
while the inverter is powered OFF. To avoid causing system malfunctions by this, interlock these signals
to keep them ON using an external power supply. Furthermore, the validity of these output signals is not
guaranteed for approximately 1.5 seconds after power-on, so introduce such a mechanism that masks
them during the transient period.
➢
Terminals [30A/B/C] use mechanical contacts that cannot stand frequent ON/OFF switching.
