584S Frequency Inverter
Stall Trip Time
A motor stall timer.
STALL TRIP TIME
If the drive operates continuously in current limit for longer than the
STALL
TRIP TIME
then a MOTOR STALLED alarm will occur.
Range:
0.1 to 3000 seconds
Default:
600 seconds
Inhibit Alarms
This menu allows certain alarm conditions to be disabled. For example, the
STALL
ALARM
must be disabled in
applications where the drive operates continuously in current limit.
Reconfigure Outputs
The Setup Parameters
RECONFIG O/Ps
menu contains parameters that govern the operation of the reconfigurable
relay outputs RELAY1 and RELAY2. (These relays are configured using the
RECONFIG O/Ps
menu which is
under
SYSTEM
) The following
RECONFIG O/Ps
parameters are provided:
AT SPEED THRESH
The relay contacts close when the drive output frequency falls within the
speed setpoint ± the
AT SPEED THRESH
parameter. The relay contacts
subsequently open when the drive output frequency differs from the speed
setpoint by more than ± the
AT SPEED THRESH
parameter.
Range: 0 to
+LIMIT FREQUENCY
. Default:
LIMIT FREQUENCY
/120.
0 SPEED THRESH
The relay contacts close when the drive output frequency is within the ±
0
SPEED THRESH
parameter of 0Hz. The relay contacts subsequently open
when the drive output frequency rises out of the ±
0 SPEED THRESH
parameter frequency band.
Range: 0 to
+LIMIT FREQUENCY
. Default:
LIMIT FREQUENCY
/120.
LOAD THRESH
This parameter determines the measured motor load at which the AT LOAD
relay will operate (change state). Range: 0 to 150%. Default: 50%
FB SPEED THRESH
The relay contacts will close when the measured motor speed is greater than
the
FB SPEED THRESH
parameter. The relay contacts close when the
measured motor speed is below the
FB SPEED THRESH
parameter.
Range: 0 to
+LIMIT FREQUENCY
. Default:
LIMIT FREQUENCY/
12.
