Hitachi X200 Series - Manual (Page 93)

CAUTION: Be careful to avoid specifying a braking time that is long enough to cause
motor overheating. If you use DC braking, we recommend using a motor with a built-in
thermistor, and wiring it to the inverter’s thermistor input (see “Thermistor Thermal
Protection” on page 4-24 ). Also refer to the motor manufacturer’s specifications for
duty-cycle recommendations during DC braking.
