Features:
- Interface Between the Single-Phase AC Power Source and Motor Load
- Combines Capability of Variable Frequency Control with Adjustable Speed Support
- Operates in Conjunction with Conveyor Systems and General-Purpose Industrial Machinery
The DELTA VFD007L21A AC Motor Drive continuously converts incoming single-phase AC power (200-240 VAC, 50/60 Hz) to adjustable frequency output and distributes controlled power to the motor to support steady-state operation of conveyor belts, simple wood cutting machines, and wire drawing equipment. Seamless speed adjustment is standard with the DELTA VFD007L21A, however using an optional external braking resistor will allow enhanced deceleration control in the event of rapid stopping requirements. The DELTA VFD007L21A has made improvements in several areas over previous fixed-speed motor control designs in addition to incorporating adjustable V/f curve and automatic torque boost capability within the VFD-L series.
The DELTA VFD007L21A provides essential motor control functions common to the entire drive system, and is a critical component of the power conversion path, directly affecting the proper, normal operation of the overall motor drive system. One DELTA VFD007L21A AC Motor Drive is required per motor depending on the desired speed control level.
For enhanced stopping performance applications, the DELTA VFD007L21A AC Motor Drive supports DC injection braking functionality integrated within the unit. In addition to standard coast-to-stop operation, the braking configuration also performs automatic DC injection during deceleration. The DELTA VFD007L21A braking configuration executes stopping using the internal circuitry specified in the drive parameters.
The VFD007L21A DELTA AC Motor Drive may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
