3.5.8 Speed Output Reading
The speed is detected by the ABSOCODER sensor is stored either as binary value of the change
amount in position within the specified time or as rotation speed (r/min.) The desired form is selected
by 'speed gate time'.
o Speed gate time: This is the time interval for detecting the sensor's travel speed. For the MRE-G[ ]
type ABSOCODER, the rotation speed is 1/gear ratio ([ ] / 32).
o Speed sampling time: This is the sampling time for the speed gate time. This item is disabled if a
"rotation speed" is set at the speed gate time.
(1) When storing binary value (Any from 0 to 4 is selected by 'speed gate time'.)
The sensor's rotation speed is stored as sensor binary value. This means that the change in
amount of speed gate time is stored in the absolute value.
The graph below shows the gate time and the sampling time.
[When sampling time = 1/2 of gate time]
The next gate time starts when the current sampling has finished.
(2) When storing rotation speed ('5' is selected by 'speed gate time'.)
This area stores the rotation speed (r/min.) internally calculated according to the current position
detected by the ABSOCODER
Notes:
Speed with symbol is set regarding the rotation direction set by address 16386 [1702] (sensor
selection/sensor rotation direction) as 'positive (+)'.
'Negative (-)' rotation speed is stored as complement of '2'.
When using the MRE-G[ ] type ABSOCODER sensor, the rotation speed to be stored is 1/gear ratio
([ ]/32 ).
