4-2 Function Mode •The Digital Operator displays until restart, after output is shut off. okokoko FW FRS Output current b028 Decelerates according to b029 Inverter output frequency Frequency selected in b030 Motor rotation speed 4 Functions Input Power Supply Phase Loss Protection Function Selection •This function outputs an alarm when the Inverter's input power supply has phase loss. Phase loss may cause the Inverter to fail, as follows: •The main capacitor ripple current increases, resulting in remarkable reduction in the capacitor's service life. •When load is applied, the Inverter's internal converter or thyristor may be damaged.
Electronic Thermal Function •Causes a trip to protect the motor from overheating. Set this according to the motor rated current. •Provides the most appropriate protection characteristics, taking into account the decline of the motor cooling capability at a low speed. •Outputs an alarm signal before an electronic thermal trip. 4-46 b003 Parameter No. Function name Data Default setting Unit b006 Input phase loss protection selection 00: Disabled 01: Enabled 00 Parameter No.
