block with the higher velocity F4000 (data parameter P100 set as 4000) at the beginning of the 1
st
axis,
pass through the block based upon the F500 (data parameter P342 set to 500) after touching the
deceleration switch, and then check the one-turn pulse z signal of the servo based upon the very slow
velocity F40 (data parameter P99 is set to 40), and lastly, it will immediately stop after capture; refer to
the Fig. 4-8-1-4.

2. The operation step using the program code mechanical zero return
The program code G28 zero return can be performed after the bit parameter
NO
：
6#3
is set to 0,
that is the reason, the inspection stroke block is shared the same efficiency with the manual
mechanical zero return.
4.8.2 Servo Zero Return Function Setting of Bus Type
There are three zero return methods when system allocates with the bus servo, which is
separately composed of common zero return, high velocity zero return and multi-coil absolute setting
zero. These setting methods are separately introduced as follows:
I. Common zero return
Set the bit parameter
No: 0#0=1, No: 5#4=0,
system can select one-turn signal or non one-turn
based upon the common zero return method of which this zero return method can used in the
increment method version of the system configuration Da98B, GE2000. The zero return along with
each axis is enabled in the zero return method.
The concrete operation steps are basic consistency with the pulse servo zero turn; refer to
the
operation steps of pulse mechanical zero return in section 4.8.1
.
II. High velocity increment zero return
Set the bit parameter
No: 0#0=1, No: 5#4=1,
the system performs the zero return based upon the
high velocity method, only the one-turn signal can be selected which can be used in the increment
version of the system configuration GE2000.
Configure the bit parameter
No: 20#7=0
,
No: 20#6=1
and
No: 20#5=0
into GE2000 series
