Overview
ESRS Description The Encoder Signal Reference Simulator (ESRS) generates a digital
speed reference for a motor and encoder feedback combination. In
practice the ESRS would be connected to the Master Encoder input of
a drive. The ESRS then generates quadrature pulses with selectable
index (i.e. marker) which a drive forces its motor/encoder to follow.
The ESRS operates in either unidirectional or bi-directional mode as
selected by the Options switch located on the printed circuit board
(PCB) of the ESRS. The rounding and acceleration functions are
operational in all modes and for all inputs including STOP.
Principal features of the ESRS
•
Selectable Internal and External Line Reference inputs plus Stop.
•
Separate Enable input, with status indication, allows for remote
control.
•
Rate of acceleration and deceleration continuously variable
between 1.5 and 15 seconds.
•
Five positions of rounding plus “OFF”.
•
Powered with a single +5V or +12V DC input voltage taken from
either the drive’s Encoder connector or external power supply.
•
User selectable Index pulse in the range 2

counts.
•
Motor speed selectable in the range 1875 to 15000 RPM.
•
Product housed in a rugged steel box with mounting tabs.
•
Operates in Unidirectional and Bi-directional mode.
•
Separate square wave “STROBE” output, which is synchronized
with the Index pulse, for triggering stroboscopes, oscilloscopes,
and so forth.
•
Analog output indication of commanded speed.
