INTRODUCING THE ML–TRIM
The ML–Trim is a highly accurate, digital, motor controller. 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) or as a part of a complex
multi-drive system (Follower mode).
The ML–Trim 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 ML–Trim adds accurate digital control to virtually any AC, DC, Servo,
Flux Vector or Clutch drives. The ML–Trim 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 ML–Trim is unique among its competition because the ML–Trim has preprogramed
software that integrates with your system with little effort from you. The ML–Trim 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 ML–Trim'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
ML–Trim's Monitor Parameters (MPs) allow you to monitor your system's performance.
The ML–Trim'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 ML–Trim's advanced capabilities is the flexibility to
preset up to four setpoint entries.
Integrating the ML–Trim's applied intelligence with your system puts precise speeds
and perfect synchronization at your fingertips, quickly, easily and cost effectively.
