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.
