 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.
 This terminal command can be assigned only by E98 or E99.
 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.
 This terminal command can be assigned only by E98 or E99.

Signal Assignment to [Y1] to [Y3] (Transistor signal)
Signal Assignment to [Y5A/C] and [30A/B/C] (Relay contact signal)
E20 to E22, E24, and E27 assign output signals (listed on the next page) to general-purpose,
programmable output terminals [Y1], [Y2], [Y3], [Y5A/C], and [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 [Y1], [Y2], and [Y3] are transistor outputs and terminals [Y5A/C] and [30A/B/C] are
relay contact 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
deenergized 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 source. Furthermore, the validity of these output signals is not guaranteed fo
r
approximately 3 seconds after power-on, so introduce such a mechanism that
masks them during the transient period.
• Terminals [Y5A/C] and [30A/B/C]) use mechanical contacts that cannot stand
frequent ON/OFF switching. Where a frequent ON/OFF switching is anticipated (fo
r
example, limiting a current by using signals subjected to inverter output limit control
such as switching to commercial power line), use transistor outputs [Y1] through [Y3]
instead. The service life of a relay is approximately 200,000 times if it is switched on
and off at one-second intervals.
