Getting Started - Hitachi L100-M Series Addendum Manual

Getting Started

This section provides specification details for L100-M Series inverters corresponding to
Chapter 1, "Getting Started," in the L100 Inverter Instruction Manual.
Main Features
Congratulations on your purchase of an L100-M Series Hitachi inverter! Like the
standard L100 Series inverters, this inverter drive features state-of-the-art circuitry and
components, exceptionally small footprint, and high performance. The Hitachi L100-M
product line includes three additional inverter models to cover motor sizes 1/4, 1/2, and
1 horsepower in 100VAC power input versions. The main features are:
• 100V Class inverters
• UL versions, type -MFU2 and -MFR2 (see note below)
• V/f (volts-per-hertz) control algorithm, selectable for either constant or reduced torque
loads
• Convenient keypad for parameter settings
• Three-wire control interface
• Up/Down electronic motorized speed pot function
• Built-in RS-422 communications interface to allow configuration from a PC and for
field bus external modules.
• Sixteen programmable speed levels
• Two-step acceleration and deceleration curves
• PID control adjusts motor speed automatically to maintain a process variable value
NOTE: The -MFU2 and -MFR2 product types have the same features, with the follow-
ing exception: The intelligent inputs on the -MFU2 models are the sinking type (require
a connection to +24VDC to turn ON). The intelligent inputs on the -MFR2 models are
the sourcing type (require a connection to logic GND to turn ON). See "Wiring Diagram
Conventions" on page 21.
The design in Hitachi inverters overcomes many of the traditional trade-offs between
speed, torque and efficiency. The performance characteristics are:
• Output frequency range from 0.5 to 360 Hz
• Continuous operation at 100% torque within a 1:10 speed range (6/60 Hz / 5/50 Hz)
without motor derating
