(d) Details of cam position compensation
POINT
Adjust the sensor position and cam position compensation target position so
that the sensor position is detected before the cam axis one cycle current value
exceeds the cam axis one cycle length.
If the sensor position is detected after the cam axis one cycle current value
exceeds the cam axis one cycle length, the sheet length may be determined as
extremely short, causing a rapid movement such as the cam axis feed current
value is increased in a short time.

The cam position compensation processing compensates the difference between the target position
for detecting the sensor and the actual position for detecting the sensor by shifting the cam axis one
cycle current value. ccyl', the cam axis one cycle length (sheet length) after compensation, is
calculated as follows:
CCYL: Cam axis one cycle length ([Cam control data No. 48])
CPHV: Cam position compensation target position ([Cam control data No. 60])
ccyl': Cam axis one cycle length (after compensation)
cpos: Cam axis one cycle current value at sensor detection
CPHV - cpos: Distance between the target sensor detection position and actual sensor detection
position
