Digital output configuration:
The screen
provides an easy selection of assigning
stroke limit switching points over the entire
stroke length of the actuator. Each of the two
output channels have a selection of up to
nine independent switching points for up to
eight independent stroke setpoints. The
selection of each switching point can be
active high or active low. If not all switching
points are used a negative one in the field
switch position will turn off the associate
fields.
Hysteresis:
The selected hysteresis number
provides a negative and positive band around
the selected switching point. This number
should be selected large enough to avoid
shattering of the output signal and small
enough to provide the desired position
accuracy.
Function of Output 4 (EPS06 only):
Output channel four can be switched from a
position limit output signal to a Pulse Width
Modulation (PWM) output signal. The signal
parameters are selected in the following
“Analog Output Configuration” screen
description. The PWM signal has a carrier
frequency of 1kHz and the “on” and “off”
time of the square pulse signal is
proportional to the selected stroke length.
The signal output is immune to noise and an
inexpensive alternative to analog input
channels on customers PLC control
equipment.
Impulses per Revolution of Square
Wave Signal at Output 5+6 (EPS06
only):
The frequency of the 90° phase shifted
A B encoder signal can be selected from
32, 64, 128, 256 pulses per revolution of
the sensor head. This gives the user a
wide range to adapt the encoder to VFD
or PLC input cards.
