Fuji Electric FRENIC-MEGA - Cancel PG Alarm-PG-CCL (Function Code Data=77); Run Forward-FWD (Function Code Data=98); Sequence with an Emergency Switching Function-Part 2 (Automatic Switching by the Alarm Output Issued by the Inverter)

5-77
3) Sequence with an emergency switching function --Part 2 (Automatic switching by the alarm output issued by the
inverter)
■ Cancel PG alarm-- PG-CCL (Function code data = 77)
When this terminal command is ON, the PG wire break alarm is ignored. Use this terminal command when switching
PG wires for switching motors, for example, to prevent it from being detected as PG wire break.
■ 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

Terminal [Y1] to [Y4] Function
Terminal [Y5A/C] and [30A/B/C] Function (Relay output)
E20 through E24 and E27 assign output signals (listed on the next page) to general-purpose, programmable output
terminals [Y1], [Y2], [Y3], [Y4], [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], [Y3] and [Y4] 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 supply. Furthermore, the validity of these output signals is not guarantee

for approximately 1.5 seconds (for 22 kW or below) or 3 seconds (for 30 kW or above) after power- ON, so
introduce such a mechanism that masks them during the transient period.
