The axis will travel 100,000 * (75 * 10 -6 * 4) = 30 counts per one controller sampling time. If
the position is PX=975 at a certain sampling time, the position should be PX=1005 at the
next sampling time. PX=1005 is beyond XM[2]; therefore, the cyclical counting makes
PX=5. The condition PX > HL[3] is missed, although it did exist.
Example:
A motor rotates at a constant speed of 4000 counts/second, with
XM[1]=-1000, XM[2]=1000
The PX variable will behave as depicted in the following graph:

P osition (P X )
The PX variable changes in the range [XM[1]…XM[2]-1], which is [-1000…999] in this
example.
The PY variable counts the distance traveled by the auxiliary encoder. It is counted in the
range [XM[1]…XM[2]-1], similarly to PX.
12.2 Digital Inputs
SimplIQ drives have six digital input pins, which must be associated with functions
before being used. Each pin can be associated with the Enable, Stop, RLS, FLS and Begin
functions. Two digital inputs are connected to high-speed hardware counters. These pins
can also be associated with the Home function. The association of input pins to functions
is described in detail in the IL[N] command section of the
SimplIQ Command Reference
Manual.
12.3 Digital Outputs
SimplIQ drives have two digital output pins, which must be associated to a function
before being used. The functions may be general-purpose output, the Amplifier Ready
(AOK) indication or brake output. The association of output pins to functions is
described in detail in the OL[N] command section of the
SimplIQ Command Reference
Manual.
