Programming Reference 8-9
If F-09 = 0, the output is energized only when the RUN LED is on.
If F-09 = 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 F-09 = 2, the output is energized when the drive is running and at speed.
.
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. (Refer to table 2.2 for the derated ratings at the
various carrier frequencies).
Normally, the maximum speed reference (the amount of reference at maximum speed,
F-04) is either 10 VDC or 20 mA. The reference gain is used to scale the speed
reference to another value (for example, 9.5 VDC or 19 mA). Enter the parameter
value in percent of full scale reference.
F-09 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.
