Technical Specifications
3.5 Encoder Matching Module Absolute 4 (Synchronous–Serial)
Here the switch position (see section 7.3.1) must be considered!
1st case: Binary setpoints and actual binary values (up to 20 bits)
Typical processing time per setpoint/actual value comparison msec
2nd case:
BCD setpoints and actual BCD values (up to 20 bits)
Typical processing time per
setpoint/actual value comparison msec
3rd case:
BCD setpoints and actual binary values
–
<10 bits typical processing time
1.4 msec
(Attention: Observe switch position according to
section 7.3.1; otherwise up to 3 msec maybe required)
– Up to 17 bits
minimum 3
msec
maximum 13 msec
4th case: Binary
setpoints and actual Gray code values
Typical processing time per
setpoint/actual value comparison msec
4. General
With the typical processing times of 1 msec per setpoint/actuaI value comparison, the following
(continuous) tolerances can be reached:
—
60 m/min.
+–
2 mm Tolerances
—
6 m/min.
+– 0.2 mm Tolerances
—
0.6 m/min.
+– 0.02 mm Tolerances
—
0.06 m/min.
+–
0.002 mm Tolerances
During transfer of new
setpoints to the module, the actual value acquisition
is delayed and the indicated tolerances are increased.
