AC Drives Control Techniques Emerson Commander SX

Frequency converter Commander SX developed by Control Techniques for industrial areas in which electrical equipment (electric drive) may be adversely affected by the environment. The sealed housing of the Commander SX electric drive with a degree of protection IP66, NEMA 4X does not allow dust, soot, steam, water splashes to get inside, and thus ensures high reliability of electronics and power elements. The element base on which the converter is assembled allows this equipment to be operated in an extended temperature range from - 10C..+50C.

Technical characteristics of the Commander SX frequency converters

• Rated power: 0.37 – 11 kW; 
• Supply voltage ratings: 220 /380 V; 
• Degree of protection: IP66; 
• Temperature regime: -10˚C..+50C(operation) /-40C..+60C (storage); 
• The ability to connect external EMC filters and brake resistors. 
• Protection functions: phase interruption, low/high voltage, motor overload, thermal overheating of the electric drive and electric motor, short circuit. 

Advantages of using Commander SK frequency converters

• easy setup and commissioning of electrical equipment (using the free SX –Soft software, automatic configuration function); 
• built-in logic controller for controlling external modules and devices; 
• installation of the electric drive in the working area next to the electric motor (reduction of the length of the shielded cable connection, high noise immunity); 
• the housing with protection degree IP66, NEMA 4X fully protects the drive from the negative effects of moisture and dust; 
• the absence of ribs on the body ensures the efficiency of its cleaning (very important for the food industry); 
• high-precision control mode using a feedback sensor. 
• copying parameters as a means of scaling typical solutions. 

Operating modes of the Commander SX frequency converters

• U/f (volt-frequency) control /scalar control of an asynchronous electric motor; 
• vector control of an asynchronous electric motor in an open circuit; 
• vector control of an asynchronous electric motor in a closed loop (using a feedback sensor – PX-Encoder option); 

Configuration of inputs/outputs of the Proxidrive electric drive

• 2 programmable analog inputs (0-10 V, 0-20 mA, 4-20 mA); 
• 1 programmable analog output (0-10 V, 0-20 mA); 
• 5 digital inputs +1 digital output; 
• 2 built-in relays (operating current 2A); 
• encoder connection connector (optional); 
• RS485 connector (Modbus RTU protocol).
