Chapter 7 Usage of Various Functions
7-83
10) External Input Stroke High/Low Limit
• External input stroke limit includes External input high limit signal and External input low limit signal.
• This is used to stop the positioning function promptly before reaching Stroke limit/Stroke End of the Driver by installing the
stroke limit inside Stroke limit/Stroke end of the Driver.
• If it deviates the high limit, Error H53 will occur and if it deviates the low limit, Error H54 will occur.
• External input stroke limit can be set in KGLWIN parameter
• High/Low limit input contact point is fixed to P0,P1 for ch0 and P2,P3 for ch1.
• If positioning module stops out of the range available to control, the positioning operation does not work.
If it stops by external input stroke limit detection, move within the range of positioning module available to control by
manual operation (Jog operation).
• As external input stroke high/low limit error is detected by the edge of positioning module, it is available to release the
output prohibit out of stroke range and carry out manual operation.
• The flags related with external input stroke limit are as followings.
- F284(Ch0) Off : External input stroke Low limit has not detected, On : External input stroke Low limit has detected
- F285(Ch0) Off : External input stroke High limit has not detected, On : External input stroke High limit has detected
- F304(Ch1) Off : External input stroke Low limit has not detected, On : External input stroke Low limit has detected
- F305(Ch1) Off : External input stroke High limit has not detected, On : External input stroke High limit has detected
Point
If external input stroke High/Low limit signal is occur during origin return, it stops operation immediately,
Then, changes direction and continues origin return operation.
11) M Code function(After Mode)
This function made to set “M Code Set” bit, if “M Code Enable“ bit was “On” when positioning was completed.
And Then “M code Set” bit must reset for run to the next step.
• Used special relay.
Device Description Remark
M1911 M Code Enable Bit(Ch0) On : Set up ”M Code” function
M1912 M Code Set Bit(Ch0) If positioning complete then “set”
M1913 M Code Enable Bit(Ch1) On : Set up a “M Code” function
M1914 M Code Set Bit(Ch1) If positioning complete then “set”
