variable
DETAILED DESCRIPTION:
The SRC(enc_src) command is used to select the input source used in Follow and Cam modes.
The SRC command allows the SmartMotor to use the many advanced following and camming
functions even without an external encoder input. For example, through the use of the SRC
command either the external encoder or a fixed-rate "virtual encoder" can be used as the
input source to the cam. This fixed-rate encoder also works through the Follow mode, so the
actual rate into the cam can be set. For more details, see Follow Mode with Ratio (Electronic
Gearing) on page 137.
Refer to the following table for valid enc_src values.
Value of
enc_src
Result
-2 -1 * internal time base at PID rate
-1 -1 * external encoder: MF0 or MS0
0 Null (no counts, standstill)
1 External encoder: MF0 or MS0
2 Internal time base at PID rate
