(PR) #1288 ext24
bit0: MDI program clear
Select whether to clear the MDI programs when MDI operation ends, the power is turned ON again, reset is
input, or emergency stop is canceled.
0: Not clear.
1: Clear (save only % programs).
bit2: Restore previous program before external search by NC reset
Select whether to restore the previous program before external search when operation is finished, power is
turned OFF and ON, NC reset is input or Emergency stop is cancelled.
0: Not restore the previous program before external search
1: Restore the previous program before external search
bit3: Restore previous program before external search by Program restore signal
Select whether to restore the previous program before external search when Program restore signal is input.
0: Not restore the previous program before external search
1: Restore the previous program before external search
(PR) #1289 ext25
bit0: Tool radius compensation switch corner judgment method (Nose R comp.)
Select the criterion to execute the outer rounding at the small corner in tool radius compensation.
(L system)
0: The corner angle is 0°; linear-linear; G02-G03/G03-G02; the radius is the same. (Conventional method)
1: The corner angle is 1° or smaller; linear-linear; G02-G03/G03-G02; the radius is almost the same. (Meth-
od for rounding minute corner angle)
(M system)
0: The corner angle is 1° or smaller; linear-linear; G02-G03/G03-G02. (Conventional method)
1: The corner angle is 1° or smaller; linear-linear; G02-G03/G03-G02; the radius is almost the same. (Meth-
od for rounding minute corner angle)
(PR) #1290 ext26
Not used. Set to "0".
(PR) #1291 ext27
bit2: Variable command: Reset operation for tool function T code (#4120/#4320)
Select how reset operation affects the address T's modal information (#4120/#4320).
0: Clear the information
1: Retain the information
(PR) #1292 ext28
bit1: Address F given in sync tap cycle
Select the specification of address F given in synchronous tapping cycle.
0: The value given to address F in synchronous tapping cycle is treated as the feed rate. Feed command
follows the setting of "#1268 ext04/bit2 Enable synchronous tapping per minute". F modal status is un-
changed.
1: Follow the G code group 5 modal status, irrespective of the setting of "#1268 ext04/bit2 Enable synchro-
nous tapping per minute". The F modal value given in the program is treated as the feed rate.
bit5: Selection of sub program call operation in fixed cycle mode
Select the operation to be carried out when sub program call (M98/M198) and either an axis address or ad
dress R (for hole drilling cycle) are given in one block during fixed cycle for drilling or turning machining.
0: Not execute fixed cycle operation in the sub program call block.Sub program call is executed after trav-
elling to the position specified by the axis address in modal status of G code group 01. Neither the axis
address nor address R affects the subsequent fixed cycle operation.
1: Execute fixed cycle operation in the sub program call block before executing the sub program call. The
axis address or address R is treated as the fixed cycle argument.
