NEMA 4X AC Drives

The ACN series of NEMA 4X sensorless vector AC drives bridge the gap between a micro drive and high-performance VFD. These AC drives have features normally only found on more expensive drives, in a NEMA 4X enclosure and at a great price.

These drives offer an advanced remote keypad, Ethernet option cards so the drive can communicate over Modbus TCP and EtherNet/IP, and the option to configure and program using the free, user-friendly VFD Suite software.

ACNxx series drives support 4 control modes which include V/Hz, slip compensation, sensorless vector and torque control.

• 230VAC: three-phase up to 20hp, single phase up to 10hp
• 460VAC: three-phase up to 30hp, single-phase up to 15hp
• Single-phase UL Ratings - 230 or 460 VAC input
• Can be used with AC induction motors or permanent magnet AC motors (PMAC)
• Lockable, integrated disconnect or no-disconnect models
• Output frequency to 400Hz (120Hz sensorless vector)
• STO - Safe Torque Off (SIL2)
• Built-in user sequence programming of 18 steps
• Optional LCD text-based keypad can be remotely mounted with IP66 case
• Local/Remote control mode selection or digital/comm input with Hand/Off/Auto control
• Momentary power loss restarts
• Analog I/O - configurable 2 Inputs and 1 output
• 2-motor control
• Built-in dynamic braking
• PID controller - including sleep and wake
• High speed communication interfaces with MODBUS RTU built-in, with optional EtherNet/IP and ModbusTCP communication card
• Fire Mode - Run fire mode during emergencies to have uninterrupted smoke removal and system pressure

The DURApulse GS20X new generation high performance vector control drives provide many standard and advanced functions - all in a compact unit that has been reduced 40% in size. The NEMA 4X version provides service in the harshest of environments.

The drives include many of the same standard features as our GS family of drives including dynamic braking, PID, and RS-485 Modbus communication.

The GS20X drive expands the DURApulse family by adding single-phase input capability (ALL 230VAC drives can be supplied single-phase), a built-in PLC, and optional EtherNet/IP and ModbusTCP communication card. The drive supports up to four (4) independent IM motor parameter sets or supports control of a single AC PM motor.

DURApulse GS20X AC drives offer several different speed control modes: standard V/Hz with pulse input feedback, sensorless vector (SVC) for Induction Motors (IM) and Permanent Motors (PM), and ultra-precise Field Oriented Vector control (FOC) for maximum open loop speed regulation control.
