Quadrature Mode - Omega iServer Microserver User Manual

4.7.1.6 Quadrature Mode

This mode configures device to operate with two 90° phase shifted input signals A and B
from linear or rotational revolvers. The counting direction of Channel A is automatically
derived from the phase of the signals A and B that is designed for very fast, high-pulse
rate totalizing measuring and positioning applications and to utilize the outputs of Rotary
Pulse Generators (RPG's), Tachometers, Motion Monitors and Controls Devices or
Equipments.
If Channel B input is disconnected its displayed Value will be the value of input signal of
Channel A and device is counting and displaying Channel A input signal as totalized
values on Channel A section of Chart.
For proper connection and configuration:
Connect the main counting OUTPUT of RPG's to channel A and the
•
Quadrature OUTPUT of most RPG's to Channel B.
Access Configuration Page and Select Quadrature option from Device Type
•
Selection (Operation Mode) Pull-Down Menu.
For Quadrature Mode ID, observe Message Item Window and notice items following:
a= Quadrature Mode
c=CH A input count value is totalizing until users manually reset
d=CH B input count value is Quadrature Signal or is actually Channel A input
frequency or rate with phase shifted normally 90° if Channel B input
disconnected
j= not applied ( previous Number of Batch Mode Measurement)
k= not applied ( previous Number of Batch Mode Measurement)
Make certain that Debounce Time must be zero when operating with
frequency signals.
