Motor Overload Protection

Hitachi X200 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 1.0 * 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.
