FDT_PULSE:
The inverter can generate a pulsed output signal for
100ms via the multi-function output terminals when
its output frequency is above the Frequency
Detection Level set in [I/O 39]. The output is pulsed
again when the output frequency goes below the
Frequency Detection Level frequency minus the
Frequency Detection Bandwidth [I/O 40].
[OC1 Configured as ‘FDT-PULSE’]
FDT_BAND:
The inverter can generate an output signal via the
multifunction output terminals whenever its output
frequency falls within its programmed bandwidth
[I/O 40]. The output is turned off when the output
frequency goes outside the Frequency Detection
Bandwidth centered on the Frequency Detection
Level frequency.
[OC1 Configured as ‘FDT-BAND’]
OL:
[Overload Signal]
When the output current is above the overload
warning level set in FUN 47 [OL level] for overload
duration time set in FUN 48 [OL time], the inverter
can generate an output signal via the multi-function
output terminals. The output signal will turn off once
the current output level falls below the value of
[FUN 47] and hold for more than half of the time set
in [FUN 48].
[OC1 Configured as ‘OL’]
STALL:
Whenever the inverter stalls, the inverter can
generate an output signal via the multi-function
output terminals. This is true throughout
acceleration, deceleration and steady state
conditions.
