§ During movement to home, the home position could not be
detected within a predetermined pulse (p0 pulse) (1st time
is jam notification, 2nd time is SC notification).
§ During movement from home, the home position was
detected even after a predetermined pulse (p1 pulse)
elapsed (1st time is jam notification, 2nd time is SC
notification).
The return pulse to home and pulse coming from home during
normal operation are calculated and measured. The pulses
which are 1.5-2 times the normal operation pulse are taken as
p0 and p1.
