Description
4
FDT-4
Relay changes state based on separate conditions for acceleration and
deceleration.
In acceleration: Operation frequency Detected frequency
In deceleration: Operation frequency>(Detected frequency–Detected
frequency width/2)
Example: Detection frequency (OUT-57) is 30 Hz. Frequency bandwidth
(OUT-58) is 10 Hz. During acceleration, relay changes state when output
frequency reaches detection frequency. During deceleration, the relay
changes state when the output frequency is below the frequency
bandwidth/2.
5
Overload
Relay changes state when inverter trips on motor overload.
6
IOL
Relay changes state when inverter trips on inverter overload. See section
5.8.5.1 for more details.
7
Underload
Relay changes state when inverter trips on motor underload.
9
Stall
Relay changes state when the inverter detects a motor stall condition.
10
Over voltage
Relay changes state when the inverter trips on Over Voltage.
11
Low Voltage
Relay changes state when the inverter trips on Low Voltage.
12
Over Heat
Relay changes state when the inverter trips on Overheat.
13
Lost
command
Relay changes state when the inverter trips on Lost Command. Lost
command includes lost reference frequency from:
Analog input
RS-485 communication
Option Cards (Extended I/O and communications)
14
RUN
Relay changes state when a run command is applied and the inverter outputs
voltage. There is no output when reference frequency is at zero or during DC
braking.
Note
When using communications or RS-485 for speed reference, if speed
reference is lost the protection operates based on the time set at PRT-
13 (Lost Cmd Time).
