Siemens variable frequency control cabinet

Variable frequency control cabinet:

Using a frequency converter to control the dragged motor can achieve stepless speed control by changing the frequency of the motor during the control process, usually between 0-400Hz< It has multiple protection functions such as overload, short circuit, and phase loss protection, motor over temperature and leakage protection, and complete status display, which can achieve soft start and deceleration stop

Control method:

It is divided into two types: on-site control and remote control. The control methods include manual control, terminal control, PLC control, and communication control.

Frequency modulation method:

Manual frequency modulation, analog frequency modulation (0-10V/4-20mA), switch frequency modulation (multi speed), communication setting frequency, etc.

Typical applications of variable frequency control cabinets:

Industrial machinery equipment such as fans, water pumps, constant pressure water supply, decanters, central air conditioning, papermaking machinery, textile machinery, etc., with a control motor power range of 0.18-250KW.
