There are 9 MCC05v2 machine origin detection types in all, namely, ORG-0,ORG-1,ORG-2,ORG-3,ORG-4,ORG-5,ORG-10,
ORG-11 and ORG-12.
The X axis, Y axis , Z axis and A axis are provided independently with this function,
so mutual interference does not occur.
In each process of ORG-0 to ORG-5 and ORG-11 to ORG-12, the machine origin address once detected is stored in
memory, thereby permitting machine origin detection in a short time thereafter. Therefore, a detection flag is
prepared inside the MCC05v2.
When this flag is ON, movement is performed nearly up to the machine origin( OFFSET PULSE) by
ABSOLUTE INDEX DRIVE, then DRIVE of the processes shown in and after 7-2. is performed.
When the flag is OFF, DRIVE of each process is directly performed without performing ABSOLUTE INDEX DRIVE.
The following description is given about the X axis but also applicable to the Y axis, Z axis and A axis.
＊Detection flag ON condition
① The machine origin was normally detected by ORG DRIVE.
＊Detection flag OFF conditions
① POWER ON/RESET
② DRIVE was put into an fast stop by the FSSTOP signal or the FSSTOP command.
(Including an fast stop by the match output of COMPARE REGISTER)
③ ORIGIN DRIVE was stopped by the SLOW STOP command and etc.
(Including DEND ERROR or ORIGIN ERROR was occurred.)
④ When the LIMIT stop type was set to fast stop, DRIVE was stopped by the LIMIT signal.
⑤ ORG DRIVE different from the previous ORG DRIVE was started.
⑥ ADDRESS exceeds the range of +8,388,607 to -8,388,607.
⑦ The ORIGIN FLAG RESET command or SPEC INITIALIZE4 Command was executed.
・The machine near-origin address for making a return with the detection flag ON is controlled in the MCC05v2,
so the user does not need to consider anything. Even if ADDRESS has been updated by the ADDRESS INITIALIZE
command, the machine near-origin address is also update, so the physical location is stored in memory.
・The machine near-origin address depends on the ORG type. In the ORG-0 to ORG-3, ORG-11 and 12 types,
the machine near-origin address is the location of "machine origin detection end po OFFSET PULSE".
In the ORG-4,5 types, the machine near-origin address is the location of "NORG OFFSET PULSE".
The OFFSET PULSE is specified in the range of 0 to 255 pulses by the OFFSET PULSE SET command.
OFFSET PULSE becomes 0 at POWER ON/RESET.

・Standard number of processes
Indicates the number of DRIVEs of CONSTANT SCAN, SCAN and JOG started by ORIGIN DRIVE.
Regarding JOG DRIVE, however, the repeated JOG DRIVE process is 1.
・Accuracy
A denotes the top accuracy and the accuracy is lowered in the order of B and C.
In the following process drawings, the meaning of each symbol is as follows.
XORG,XNORG
Indicates a sensor signal. (Low with the sensor ON)
Mark ○
Indicates the detection start position.
Mark △
Indicates the detection end position.
→
Indicates SCAN DRIVE and its direction.

LD
Indicates a stop during LIMIT DELAY TIME.
SD
Indicates a stop during SCAN DELAY TIME.
JD
