Software Operating Features
The General Purpose Quattro-DC elevator
drive is a four-quadrant torque and speed
regulated motor drive with low power line
harmonic currents and unity power factor. It
can be configured to operate geared and
gearless elevators and lifts. Basic features
include...
User choice of operating speed reference
(see pg 33)
External analog reference follower
Serial link reference follower
Internal reference generator with
controlled S-Curve smoothing to one of 15
preset speeds
User choice of ft/min or m/sec speed
programming and display units (see pg 90)
User choice of input control logic for Run-Up /
Run-Down or Run / Direction relay control
with internal preset speeds (see pg 33)
User choice of P-I type or MagneTek
exclusive E-Reg, elevator velocity
regulators (see pages 74 and 74)
Optional CEMF speed regulator for use
during initial construction stage start-up
Torque Feed-Forward when available from
the car controller (see pg 33)
Pre-Torque at drive start to reduce roll-back
(see pg 33)
Controlled torque Ramp-Down to prevent
elevator brake thumping at stops
(see pg 33)
Internal frequency notch filter to reject rope
resonance interference (see pg 49)
Closed loop motor field current regulator
with simplified motor field weakening and
stand-by adjustments
Drive Stand-by Power Reduction (see pg 34)
User selectable choices for relay logic
outputs, including (see Logic Outputs C3
submenu on pg 81):
Drive OK / No Faults relay
Alarms Relay
Drive operating, OK to release brake
Car above/below speed X threshold
Car above/below Zero speed threshold
Car Moving Up
Car Moving Down
Speed Error above/below X threshold for Y
secs
Drive Standby Power Reduction (DSPR)
Elevator Brake actuation
User selectable analog trace outputs for
system diagnostics (see Analog Outputs C4
submenu on pg 83)
Diagnostic indicator for verifying logic input
and output conditions
Programmable Alarm Relay to indicate
important but non-critical conditions
Motor thermostat over-temperature
Motor Over-Load
Drive Over-Heating
Low Utility Line Input
Safety related fault trapping with
diagnostics, including:
Motor Over-Current
Motor field Malfunction
Contactor Failure
Severe Utility Line disturbances
Encoder Loss
Over-Speed Trip
User selectable automatic or external
commanded Fault Reset (see User
Switches C1 submenu on pages 64-72)
EN81-1 Safe Off Feature, single contactor
Drive Model Numbers
The Quattro DC drive is currently available
with five different output currents and a variety
of options.
The enclosure option consists of a customer
I/O panel. The customer I/O panel is an
optional larger width cabinet that allows for
customer interfacing within the supplied
cabinet. See Dimensions / Weights on page
141.
