Controller Functions
D START/STOP
D RUN/JOG
D FORWARD/REVERSE
D Speed selection (5 to 100%)
D Unidirection operation with coastĆtoĆrest on stop command standard. (Dynamic
braking and reversing available as options.)
D 20:1 controlledĆspeed range by means of armature voltage control.
D Auxiliary Panel armature loop contactor removes power to drive motor.
D Isolated armature voltage and current feedback decouples armature power from
operator devices and provides additional noise immunity.
D With specified tachometers 0.5% or 1.0% speed regulation with a 95% load change.
D Operates and delivers rated output speed with specified regulation tolerance limits
even with aĆc Line variations of +/-10% of nominal rated input voltage.
Speed Regulation
D Jumper reconnectable regulator circuits which allow armature (A) or tachometer
feedback (T) regulation.
D With voltage regulation, 3 to 5% speed regulation with 95% load change.
D With tachometer specified, 1% speed regulation with a 95% load change.
(Tachometers are: REĆ045 aĆc tachometer; also 5PY or REĆ020 dĆc tachometer.)
D With tachometer specified, 0.5% speed regulation with 95% load change.
(Tachometer is BC42.)
User Adjustments
D Adjustable IR drop compensation (0 to 12% of rated load).
D Adjustable maximum speed (70 to 100% of base motor speed).
D Adjustable minimum speed (5 to 30% of base motor speed).
D Adjustable current limit (10 to 150% of fullĆload current).
D Adjustable, separately set linear acceleration and deceleration rates (0.5 to 30 sec.)
Safety
D Control circuitry guards against automatic restarting of equipment after resumption
of interrupted aĆc incoming power.
D Regulator and Operator's Controls isolated from aĆc line for personnel protection.
D Armature voltage and current feedback isolated to assure separation of power and
regulator circuits.
Hardware
D Conveniently located screw terminal connections for incoming aĆc and outgoing
dĆc power allow easy cable entry and connection.
D Auxiliary Panel aĆc line fuses protect Power Cube from armature short circuit and
power relays provide positive power disconnect.
D Protection from momentary surges on aĆc line and from dĆc load transients.
2.1 Operator's Controls
- For proper operation
of the FlexPak Plus controller, it is necessary to provide
Remote Operator's Controls. Reliance Electric offers a
wide variety of operator control stations which may inĆ
clude the following devices:
D SPEED control potentiometer (5K)
D TORQUE control potentiometer (10K)
D AUTO/MANUALselector switch (SPDT)
D RUN/JOG selector switch (SPST)
D FORWARD/REVERSE selector switch (DPDT)
D START/STOP selector switch (pushbuttons or speĆ
cial)
2.2 DĆC Drive Motors
- Reliance Electric offers a
complete powerĆmatched drive system for the controlĆ
ler and the application. Thus, the choice of Reliance
Electric motors assures optimum performance and unĆ
matched singleĆsource responsibility.
