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.

WARNING: 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.
