Motor Overload Protection

Hitachi L2002 inverters provide solid state motor overload protection,
which depends on the proper setting of the following parameters:

• B012 “electronic overload protection”

• B212 “electronic overload protection, 2nd motor”

Set the rated current [Amperes] of the motor(s) with the above parame­ters. The setting range is 0.2 * rated current to 1.2 * rated current.

War n in g: When two or more motors are connected to the
inverter, they cannot be protected by the electronic overload pro­tection. Install an external thermal relay on each motor.

Up/Down Keys

Function Key

• Run/Stop LED – ON when the inverter output is ON and the motor is

developing torque, and OFF when the inverter output is OFF (Stop
Mode).

• Program/Monitor LED – ON when the inverter is ready for parame-

ter editing (Program Mode). It is OFF when the parameter display is
monitoring data (Monitor Mode).

• Run Key Enable LED – ON when the inverter is ready to respond to

the Run key, OFF when the Run key is disabled.

• Run Key – Press this key to run the motor (the Run Enable LED must

be ON first). Parameter F004, Keypad Run Key Routing, determines
whether the Run key generates a Run FWD or Run REV command.

• Stop/Reset Key – Press this key to stop the motor when it is running

(uses the programmed deceleration rate). This key will also reset an
alarm which has tripped.

• Potentiometer – Allows an operator to directly set the motor speed

when the potentiometer is enabled for output frequency control.

• Potentiometer Enable LED – ON when the potentiometer is enabled

for value entry.
