General
The ESR 3000
– ESM 3000 range comprises special, adaptable controllers for use with vibratory feeders. The units
generate an output frequency, to drive feeders, that is independent of mains frequency and so exact tuning with
springs is not necessary. The feeders also run quieter because of the sinusoidal output signal. The adjusted output
frequency corresponds to the mechanical vibrating frequency of the feed system. The optimum frequency setting for a
feeder can determined manually or automatically in regulation mode.
Depending on the version, the controller can be used in regulation mode, working in conjunction with an accelerometer
fitted to the feeder, to operate at resonant frequency. In this way a constant component feed rate that is unaffected by
load changes can be achieved. In regulation mode the vibrating frequency is also dynamically adjusted to compensate
for resonant frequency changes caused by load changes. In normal operating mode (without accelerometer) the
feeder remains constant at the set frequency. In both operating modes the feeder throughput is determined by the
output voltage level.
Totally enclosed or panel mounting units can be supplied.
