Combination of M functions

• Within each line, only one 'handshake' type M function must be programmed!
• Within a single line, up to 10 'signal bit' M functions may be programmed
• A combination of the two options above is allowed

Sample:

N10 G01 X1000 F60000
N20 M10 M11 M12 X2000 (M10 & M11 are signal bits)
        (M12 is of type handshake)
M30 

Examples of meaningful and practically applicable rule combinations:

• An M-function is to be active for the duration of a movement and then be automatically cleared. Select 'None' in the HShake column and 'BMAutoReset' in the Fast column. The signal bit generated could, for instance, control a glue application valve.
• An M-function starts a drill motor, and the subsequent movements may only be started after an appropriate run-up time, and then only when the drill is ready for operation. Select 'BM' in the HShake column. The PLC acknowledges the request after a certain delay time and only if the frequency converter is ready for operation.
• A drill motor is started with an M-function. In order not to have to wait for the drive to run up, the M-function is programmed in the block before the one for the drill movement. In the following movement (the drill movement itself) it is however still essential to ensure that the drive has reached its full rotation speed. For this variant either two different M-functions have to be used (lead signal as signal bit, safety query as handshake) or a Fast 'BMAutoReset' and HShake 'AM' M-function is used.
