6-5-6 Word n+1 Bit 06: M Code Reset Bit (Task 1)
This bit resets the M code output.
If M code 0 to 499 is output in the program, that block will standby for an M code
reset. The progress through the blocks will be interrupted. In this case, the M
Code Reset Bit can be turned ON to clear the M code to 0 and turn OFF the M
strobe. Program execution will restart when this bit is turned OFF. (Keep this bit
ON until the M strobe goes OFF.)
If the M Code Reset BIt is ON when a block is executed, that block’s M code
won’t be output. When M codes 500 to 999 are being output and this bit is turned
ON, the M code will be reset whether the mode is automatic or manual.
The M Code Reset Bits for task 2 (bit 06 in word n+3) operate in the same way.
Signal The M Code Reset Bit settings have the following functions.
Signal Function
↑ (OFF-to-ON) If there is an M code reset standby (M000 to M499), the M code
