Learning Advanced Features
4 FDT-4 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.
5 Over Load Outputs a signal at motor overload.
6 IOL 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.
7 Under Load Outputs a signal at load fault warning.
8 Fan Warning Outputs a signal at fan fault warning.
9 Stall Outputs a signal when a motor is overloaded and
stalled.
10 Over Voltage Outputs a signal when the inverter DC link voltage
rises above the protective operation voltage.
11 Low Voltage Outputs a signal when the inverter DC link voltage
drops below the low voltage protective level.
12 Over Heat Outputs signal when the inverter overheats.
13 Lost Command Outputs a signal when there is a loss of analog input
terminal and RS-485 communication command at the
terminal block.
