584S Frequency Inverter
4-33
AT SPEED
The relay contacts close when the drive output frequency reaches the speed
setpoint ±
AT SPEED THRESH
.
RUN CONFIRM
Relay contacts are closed when the drive is running. Relay contacts are open
when the drive is not running.
BRAKE CONTROL
This mode is intended to control external electro-mechanical motor brakes in
lift and hoist applications. There are 3 parameters associated with this mode.
These are under the
BRAKE CONTROL
parameter. The relay contacts close
when drive frequency >
ON FREQ LEVEL
and motor load >
ON LOAD
LEVEL
. The relay contacts open when drive frequency <
OFF FREQ
LEVEL.
AT LOAD
The relay contacts close when the measured motor load exceeds the
LOAD
THRESH
parameter. The relay contacts will open when the measured motor
load falls below the
LOAD THRESH
parameter.
AT FB SPEED
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.
NOTE: For the
AT FB SPEED
relay to operate correctly the drive requires speed feedback
information from an encoder via the speed feedback option board. In addition the data concerning the
number of encoder lines and motor pole-pairs needs to have been correctly entered in the set up
parameters menu.
Reconfig I/Ps
This parameter determines the functionality of the FRAMP, JOG, PRESET1 & PRESET2 control terminals
(terminals 21, 24, 25 and 26 respectively). The following options are provided:
PRESETS & JOG
Within this menu we can choose from the options:-
4 PRESETS & JOG
With this option selected, raising the JOG terminal to
+24V causes the drive to run at the jog speed setpoint. The digital inputs
PRESET1 and PRESET2 remotely select 1 of 4 preset speed setpoints.
8 PRESETS
With this option selected, the JOG digital input is now re-
configured to select a second bank of preset speed (preset speeds 5 to 8).
DIGITAL MOP & PRESET
With this selected, the functionality of the
JOG, PRESET1 & PRESET 2 terminals are again reconfigured to act as a
digital motorised potentiometer. PRESET1 becomes RAISE, PRESET 2
becomes LOWER and JOG becomes MOP PRESET.
FRAMP
Within this menu we can choose the function of the FRAMP terminal from the
options:-
FRAMP
with this option selected, raising the FRAMP terminal to +24V and
removing the RUN signal causes the drive to ramp down with the FRAMP
TIME selected.
PID RESET
with this option selected, raising the FRAMP terminal to +24V
causes the internal PID to be held in a reset state.
2ND RAMP RATES
with this option selected, raising the FRAMP terminal
to +24V causes the
RAMP UP TIME2
and
RAMP DOWN TIME2
to be
selected as the main ramp times.
TRIP RESET
with this option selected, raising the
FRAMP
terminal to +24V,
and the RUN is input inactive, the drive will attempt to reset any trips.
