Enc Variable Frequency Drive, Variable Speed Drive, Adjustable Speed Drive

Descriptions of EDS1000 3 phase AC motor speed controller:
The EDS1000 AC drive gives OEMs, machine builders and end users performance-enhancing motor control in an easy-to-use, compact package. The EDS1000 features sensorless vector control to meet low speed torque demands helping to improve application performance.
With flexible packaging options and an uncomplicated programming structure, this drive can be quickly and easily installed and configured for a variety of applications.
Features of EDS1000 3 phase AC motor speed controller:
A relay pre-charge limits inrush current.
Variable PWM allows the drive to output more current at low Frequencies(1Hz).
Two analog input channels, including PID capability, offer enhanced application flexibility.
Integral RS485 communications let the drives be used in a multidrop network configuration.
An integral keypad provides out of the box operation using the local potentiometer and control keys.
150% overload for 60 seconds or 200% overload for 0.5 seconds provides robust ovrload protection.
Timer, Counter, Basic Logic functions can reduce hardware design costs and simplify control schemes.
Sensorless Vector Control develops high torque over a wide speed range and adapts to individual motor characteristics.

Where are speed controller Applications

Industry segments are important, because many applications are industry specific. Some classic VFD applications for various
Industries are provided below:
1. HVAC, fans and pumps.
2. Food Processing: Agitators, mixers, conveyors for food transport, packaging and bottling, preparation machines (slicers, dicers, choppers), extruders, fans and pumps.
3. Petrochemicals: Deep well pumps, oil field recovery, local distribution pumps, fans and pumps.
4. Mining and Metals: Reheat furnaces, cooling beds, run in/out tables, fans and pumps.
5. Pulp and Paper/Forest Producers: Washers, kilns, slitters, deckers, chippers, saws, sanders, peelers, de-barkers, fans and pumps, vacuum removal systems.
6. Machine Tool: Replace spindle drives, grinders, saws, lathes, tool positioning drives, balancing machines, fans and pumps.
7. Transportation: Material handling conveyors, cranes and hoists, small vehicle drives, fans and pumps.
8. Any machine or process that can be improved by varying speed or flow is a candidate for a VFD
