Control Techniques AC drives

Being tied into one system can be restrictive. It can leave you trapped with one supplier even when there’s a better option available on the market. We provide a viable alternative.

• 0.33 hp – 200 hp (0.25 kW – 132 kW) Normal Duty
• 0.33 hp – 150 hp (0.25 kW – 110 kW) Heavy Duty
• 115 V | 208-240 V | 380-480 V | 575 V | 690 V

Control Techniques’ Commander C300 variable frequency AC drive (VFD) has been designed for applications that require flexible integration withsystems via modern network and fieldbus communications and high performance RFC-A (Rotor Flux Control) open-loop motor control.

The Commander C300 is available in nine frame sizes, covering all low voltage ranges, and provides up to 132 Kw. This versatile drive has several cost and space saving features, such as “snap-in” expandable I/O or communication options and onboard PLC using IEC-61131-3 compliant programming software.

Commander C300 has been designed for applications that require flexible integration with systems via industrial Ethernet protocols and fieldbuses together with advanced open loop motor Rotor Flux Control (RFC-A).

Features

Flexible system integration with communications options

• Commander C300's SI interface module enables integration with a wide range of available industry standard communications or extended I/O such as EtherNet/IP, Modbus TCP/IP, EtherCAT, PROFINET, DeviceNet, PROFIBUS, CANopen
• AI-485-ADAPTOR and AI-485-24V-ADAPTOR options provide a connection to RS485 networks using Modbus RTU. Additionally, AI-485-24V-ADAPTOR also provides and input for 24 V backup.

Reduced system costs by directly controlling machine applications

Commander C300 incorporates an onboard PLC which can execute Machine Control Studio (IEC61131-3) programs for logic and sequencing with real-time tasks - removing the need for additional PLC's

Improve throughput with advanced open-loop motor control algorithms

• Rotor Flux Control (RFC-A) gives maximum stability and control of induction motors at all powers
• 180% motor overload suitable for heavy industrial machinery applications

Install and configure quickly and easily

• Easy-to-use fixed LED keypad
• Useful parameter guide located on the front of the drive
• Use Unidrive M Connect PC tool or SD card with AI-BACKUP-ADAPTOR or AI-SMART-ADAPTOR to clone and transfer parameter sets
• Din rail mounting is supported below 2 hp (1.5 kW)

Save energy

• Low power standby mode – drives can sit idle for significant periods
• Automatic 3-speed cooling fan –intelligently responds to load
• Square law V/F mode - optimized for quadratic loads like pumps and fans
• Dynamic V/F mode - keeps energy usage and motor losses to a minimum
• Unidrive M is 98% efficient – only 2% energy is lost in the conversion process across the drive

Minimize downtime with robust and reliable drives

• Conformal coated PCBs – for increased resilience to moisture, dust, chemicals and temperature extremes
• Patented air flow system – efficiently cools while protecting internal components
• Ingress protection up to IP21 – UL open class (NEMA 1) compliant.UL type 1 with conduit box kits
