R02/92 Matching Module 3 for Absolute Encoders
6.1
Function Description
This module is capable of converting input voltages or currents into a 10–bit binaty value (Oto
1023) plus sign.
Thus the maximum representable range covers + 1023 to –1023.
The measured value is amplified accordingly or converted from current into voltage
(OVto 10
v).
This voltage which may be positive or negative, is rectified for the ADC and the sign is derived. This
ADC is continuously started by a free–running clock pulse generator and initiates transfer to the
output memory with its ready signal.
This transfer operation is disabled while the memory is being scanned by the basic module.
A reference voltage of + 10 V is generated and is available at the front connector.
