FĆ09 Configurable Output Relay Select
This parameter specifies the type
of status indication the output
relay contacts provide (terminals
14, 15, and 16 on the Drive
terminal strip).
Parameter Range:
Default Setting:
Step Size:
0 = Output relay is energized to show
state of Drive running.
1 = Output relay is energized to show
state of active fault (IET).
2 = Output relay is energized to show
state of Drive running at speed.
0
N/A
If FĆ09 = 0, the output is energized only when the RUN LED is on.
If FĆ09 = 1, the output remains energized until the fault is cleared by pressing the
STOP
RESET key (in local
operation) or by using the remote IET reset signal (for remote operation).
If FĆ09 = 2, the output is energized when the Drive is running and at speed.
FĆ10 Carrier Frequency
This parameter selects the
Drive's carrier frequency.
Parameter Range:
Default Setting:
Step Size:
4 = 4 kHz Carrier frequency
6 = 6 kHz Carrier frequency
8 = 8 kHz Carrier frequency
4
N/A
The carrier frequency controls the width of the pulse and keeps the current smooth to the motor. This
parameter can compensate for acoustic noise, heating, and other current problems by adjusting the
switching frequency of the transistors in the inverter section.
Keeping the carrier frequency at 4kHz maximizes the continuous power rating of the Drive with,
generally, an acceptable acoustic noise level from the motor. Increasing the carrier frequency reduces
the acoustic noise, but in some applications this can result in derating of the Drive output amps.
