9 Setting the Tool Entry Prohibited Range
MITSUBISHI CNC
144
Stroke End (H/W OT) and Stored Stroke Limit (S/W OT) set the tool entry prohibited range and detect the overtravel
(OT).
9.1 Stroke End (H/W OT)
The axis movement is controlled by the limit switch which detects the stroke end.
Signal device No. is allocated by the following parameters.
Parameter "#2074" and "#2075" will be valid only when "#1226 aux10/bit" is set to "1".
#1226 aux10/bit5: Set to "1" (assigning the signal is valid).
#2074 H/W OT+: Set the input device for assinging the OT (+) signal. (Setting range 0000 to 02FF (Hexadecimal) )
#2075 H/W OT-: Set the input device for assinging the OT (-) signal. (Setting range 0000 to 02FF (Hexadecimal) )
(Note 1) When "OT IGNORED" (R2420) signal is set to ON, the stroke end signal associated with a specific control axis
can be ignored.
(Note 2) When parameter "#1226 aux10/bit5" is set to "1", do not set the same device No. to #2073 to #2075.
Setting the same device No. may cause the emergency stop. However, the device number will not be checked
for the axis which is set the signal to ignore (R2420, R2421).
