Ctrl Command read_encoder
Function Returns the counts of the two RTC6 encoder counters that were stored by store_encoder.
Call read_encoder( &Encoder0_0, &Encoder1_0, &Encoder0_1, &Encoder1_1 )
Returned
parameter
values
Encoder0_0 Count.
As a pointer to a signed 32-bit value.
For parameter “Encodern_m”:
• n is the number of the encoder counter (“Encoder0”, “Encoder1”).
• m is the number of the storage position (parameter Pos of
store_encoder).
Encoder1_0 Like Encoder0_0 (analogously).
Encoder0_1 Like Encoder0_0 (analogously).
Encoder1_1 Like Encoder0_0 (analogously).
Comments • See also Chapter 8.6 ”Processing-on-the-fly”, page 242 and Chapter 9.3.3
”Synchronization by Encoder Signals”, page 298.
• If the workpiece movement is registered with an incremental encoder:
– Encoder counter “Encoder0” is triggered by the signals at encoder input port
ENCODER X
– Encoder counter “Encoder1” is triggered by the signals at encoder input port
ENCODER Y
• If an encoder simulation has been started by simulate_encoder, the encoder counters
are triggered by an internal periodic 1 MHz clock signal.
• For storage positions in which counts were not previously stored by store_encoder,
the value 0 is returned (initialized value).
RTC4RTC6 New command.
RTC5RTC6 Unchanged functionality.
