INTRODUCING THE MLP-DRIVE
The MLP-Drive is a highly accurate, digital, motor drive which can drive 1/4 to 2
horsepower PM DC motors. It has advanced embedded software that is capable of
solving a great variety of speed control tasks. It operates as either a stand-alone
control of a single motor (Master mode), as a part of a complex multi-drive system
(Follower mode) or Follower mode with analog trim (Offset mode).
The MLP-Drive is ideal for motor control applications where your present open loop or
rudimentary closed loop operations are inaccurate or where there is inadequate load
regulation. The MLP-Drive is also at the forefront in digitally accurate Follower
applications. See Figure 1-1 and Figure 1-2 for examples of Master and Follower
applications.
The MLP-Drive is unique among its competition because the MLP-Drive has
preprogramed software that integrates with your system with little effort from you. The
MLP-Drive will also allow you to enter data that is unique to your system's specific
needs (e.g., maximum RPMs, setpoints, acceleration/deceleration ramp rates). Using
Control Parameters (CPs), this data is entered through either the MLP-Drive's
integrated keypad or though a host computer via the RS485 Serial Communications
port. In addition to the Control Parameters that allow you to customize for your systems
specific needs, the MLP-Drive's Monitor Parameters (MPs) allow you to monitor your
system's performance.
The MLP-Drive's multiple scaling formats allow you to enter the setpoints and monitor
speed in the Engineering Units (e.g., RPMs, gallons per hour, feet per minute) that are
unique to your system. Among the MLP-Drive's advanced capabilities is the flexibility to
preset up to four setpoint entries.
Integrating the MLP-Drive's applied intelligence with your system puts precise speeds
at your fingertips, quickly, easily and cost effectively.
