Intelligent Functions and Parameters
Much of this manual is devoted to describing 
how to use inverter functions and how to config-
ure inverter parameters. The inverter is micro-
processor-controlled, and has many independent 
functions. The microprocessor has an on-board 
EEPROM for parameter storage. The inverter’s 
front panel keypad provides access to all 
functions and parameters, which you can access 
through other devices as well. The general name 
for all these devices is the digital operator, or 
digital operator panel. Chapter 2 will show you 
how to get a motor running, using a minimal set 
of function commands or configuring parame-
ters.
The optional read/write programmer will let you 
read and write inverter EEPROM contents from 
the programmer. This feature is particularly 
useful for OEMs who need to duplicate a particu-
lar inverter’s settings in many other inverters in 
assembly-line fashion.
Braking
In general, braking is a force that attempts to slow or stop motor rotation. So it is associ-
ated with motor deceleration, but may also occur even when the load attempts to drive 
the motor faster than the desired speed (overhauling). If you need the motor and load to 
decelerate quicker than their natural deceleration during coasting, we recommend 
installing an optional dynamic braking unit. See 
 for more information on the BRD–E2 and BRD–EZ2 
braking units. The L200 inverter sends excess motor energy into a resistor in the 
dynamic braking unit to slow the motor and load. For loads that continuously overhaul 
the motor for extended periods of time, the L200 may not be suitable (contact your 
Hitachi distributor). For loads that continuously overhaul the motor for extended periods 
of time, the L200 may not be suitable (contact your Hitachi distributor).
The inverter parameters include acceleration and deceleration, which you can set to 
match the needs of the application. For a particular inverter, motor, and load, there will 
be a range of practically achievable accelerations and decelerations.
