GENERAL CONTROLLER INFORMATION
2.0 General Ċ The Regenerative MinPak Plus DĆC VKS
drive controller may be applied to singleĆphase dĆc drive
applications with ratings within the following ranges:
D From 1/4 to 3/4 hp with a 115 VAC, 50/60 Hz input
voltage
D From 1/2 to 5 hp with 230 VAC, 50/60 Hz input
voltage
Reliance Electric dĆc motors, which may be used with the
controller, may be either permanent magnet motors up
to 1Ć1/2 hp or wound field (excited) motors up to 5 hp.
The controller provides powerĆconversion and control
circuits which convert the aĆc line voltage into adjustable
dĆc voltage in order to effectively control the drive motor.
The drive package consists of three basic drive compoĆ
nents:
D Regenerative MinPak Plus controller
D Operator's control station
D AdjustableĆspeed dĆc motor
Optional Modification Kits conveniently expand the caĆ
pability of the basic controller.
The Regenerative MinPak Plus controller is provided, as
standard, in a NEMA Type 4/12 enclosure intended for
wall or panel mounting. It is made up of a Chassis and
hinged Cover. (Type 4 may be generally defined as a
washdown" design. A specific definition is given at
Paragraph 2.5.) The enclosure may easily be converted
into a Chassis only type configuration for panel mounting
within a larger electrical enclosure. The optional Remote
Control Station may then be placed on the larger encloĆ
sure's face or some distance away.
A doubleĆpole POWER ON/OFF circuit breaker is stanĆ
dard with each Chassis and is independent of the Cover
and Faceplate. A singleĆpole circuit breaker in the armaĆ
ture circuit protects the controller and motor in the event
of an inverting fault.
The Regenerative MinPak Plus controller, in both NEMA
Type 4/12 or Chassis configurations, is Underwriters
Laboratories (U.L.) listed and Canadian Standards
Association (C.S.A.) certified.
The regenerative control unit contains two fullĆwave, fullĆ
control power conversion modules. These power modĆ
ules, along with their associated control circuitry, allow
selective current flow through the motor armature in eiĆ
ther direction under controlled conditions. The result is
an SCR drive that is able to provide positive or negative
torque output in either direction of motor rotation.
The controller's features are summarized in Table 2.A.
2.1 Operator's Control Station Ċ For proper operation
of the Regenerative MinPak Plus controller, it is necesĆ
sary to use an Operator's Control Station. (Refer to FigĆ
ure 2.1 .)The Operator Station allows the tailoring of conĆ
trol functions for the application. These may include:
D SPEED control potentiometer
D TORQUE control potentiometer
D AUTO/MANUAL selector switch
D RUN/JOG selector switch
D FORWARD/REVERSE selector switch
D START/STOP selector switch
There are two basic configurations that may be selected:
D Station mounted on controller Chassis Cover (local)
D Station mounted as a separate unit (remote)
Nameplate
Remote Operator
Control Station
Local Operator
Control Station
Security lock lip
