Frequency inverters
Control circuit
Note:
1.The default settings are given for terminals S3 to S7. For a 3-wire sequence, the default settings are a 3-wire sequence for S5, multi-step speed setting 1
for S6 and multi-step speed setting 2 for S7.
2.Do not use this power supply for supplying any external equipment.
3.When driving a reactive load, such as a relay coil with DC power supply, always insert a flywheel diode.
