6-19.OFFSET PULSE SET Command
COMMAND………
1B
Function : Sets the number of OFFSET PULSES required for machine origin
H
detection drive.
Execution sequence
The number of OFFSET PULSES is set in DRIVE DATA3 PORT.
The contents of DRIVE DATA3 PORT are as follows.
N
BUSY=0 in
STATUS1?
DATA3 PORT
7
0
D

COMMAND 1B
WRITE
The OFFSET PULSE number setting range is 0(0 ) to 255 (FF ).
H
H
The number of OFFSET PULSES is set to 0 at POWER ON/RESET.
Once the OFFSET PULSE SET command has been executed, it does not need
to be set again unless the contents must be changed.
6-20.ORIGIN DELAY SET Command
COMMAND………
1C
Function : Sets DELAY TIME at machine origin detection drive.
H
Execution sequence
The following data is set in each of DRIVE DATA1 PORT, DRIVE DATA2 PORT
and DRIVE DATA3 PORT.
DATA1 PORT ……… LIMIT DELAY TIME (300ms(3C ))
H
N
BUSY=0 in
Delay time up to a start of reverse after a stop in the
STATUS1?
CCW LIMIT.
DATA2 PORT ……… SCAN DELAY TIME ( 50ms(0A ))
H
Y
Delay time when the direction is reversed in the CONSTANT
DATA1 PORT
SCAN and SCAN DRIVE processes.
WRITE
DATA3 PORT ……… JOG DELAY TIME
( 20ms(04 ))
H
The order
Delay time per pulse in the JOG DRIVE process.
DATA2 PORT

be observed.
In each port, the value in parentheses is set at POWER ON/RESET.
DATA3 PORT
Each data is 00
to FF and set in units of 5ms.

Usually it is not need to change this data. Only something improvement
at the machine origin detection or the tact time, etc.
The ORIGIN DELAY SET command does not need to be set again unless the
contents must be changed.
6-21.ORIGIN FLAG RESET Command
COMMAND………
1D
Function : Resets the detection flag to be used for machine origin
H
detection drive.
Execution sequence
This command is used only when you don't desire to perform
ABSOLUTE INDEX DRIVE nearly up to the machine origin when machine origin
N
BUSY=0 in
detection drive is used.
STATUS1?
For details, refer to Chapter 7.

COMMAND 1D
Note: Execute this command before executing the ORIGIN command.
