CCW software limit (leftmost word) (Hex)

CW software limit (leftmost word) (Hex)
The software limits can be set to any values in the following range:
C0000001 to 3FFFFFFF Hex ( ± 1,073,741,823 pulses)
The default settings are C0000001 (–1,073,741,823) for the CCW software
limit and 3FFFFFFF (1,073,741,823) for the CW software limit.
These settings specify the CCW and CW software limits (in pulse units). The
respective software limits are set in the range –1,073,741,823 to
1,073,741,823 pulses using two words (the leftmost word and the rightmost
word) as 32-bit unsigned data. If the CW software limit is set to less than or
equal to the CCW software limit, the software limit function be disabled and
the present position will taken to be 0 when operation starts. For details on
software limit operation, refer to 9-9 Software Limit.
The word addresses and enable timing for the initial pulse designation are
shown below.
