Learning Advanced Features
The output signal can be separately set for acceleration
and deceleration conditions.
• In acceleration: Operation frequency Detected
frequency
• In deceleration: Operation frequency > (Detected
frequency–Detected frequency width/2)
Detected frequency width is 10 Hz. When the detected
frequency is set to 30 Hz, FDT-4 output is as shown in
the graph below.
Outputs a signal at motor overload.
Outputs a signal when the inverter input current
exceeds the rated current and a protective function is
activated to prevent damage to the inverter, based on
inverse proportional characteristics.
Outputs a signal at load fault warning.
Outputs a signal at fan fault warning.
Outputs a signal when a motor is overloaded and
stalled.
Outputs a signal when the inverter DC link voltage rises
above the protective operation voltage.
Outputs a signal when the inverter DC link voltage
drops below the low voltage protective level.
Outputs signal when the inverter overheats.
Outputs a signal when there is a loss of analog input
terminal and RS-485 communication command at the
terminal block.
Outputs a signal when communication power is present
and an I/O expansion card is installed. It also outputs a
signal when losing analog input and communication
power commands.
Outputs a signal when an operation command is
entered and the inverter outputs voltage.
No signal output during DC braking.
