*3: The protection method conforms to JIS C 0920 (IEC 60529).
*4: To operate the motor beyond 50 / 60Hz, consult the motor manufacturer for the maximum allowable rotation speed.
*5: The braking torque via capacitive feedback is the average deceleration torque at the shortest deceleration (stopping from 50 / 60Hz as indicated). It is not continuous regenerative braking torque. The average deceleration
torque varies with motor loss. This value decreases when operating beyond 50Hz. If a large regenerative torque is required, the optional regenerative braking unit and a resistor should be used.
*6: 1-phase 100V class is only with CT.
*7: The frequency command is the maximum frequency at 9.8V for input voltage 0 to 10VDC, or at 19.8mA for input current 4 to 20mA. If this characteristic is not satisfactory for your application, contact your Hitachi representative.
*8: The storage temperature refers to the short-term temperature during transportation.
*9: Conforms to the test method specied in JIS C 60068-2-6:2010 (IEC 60068-2-6:2007). For the model types excluded in the standard specications, contact your Hitachi sales representative.
