January 2012 8.7 S Function (S Strobe) 1563
When the spindle speed or mode of rotation is changed in the T, S, F menu
or the NC program, a strobe signal is generated and communicated to the PLC
via the operand defined in MP_signal. At the same time the NC transmits the
programmed spindle speed in the PLC word defined in MP_spindleSpeed
and the constant cutting speed in the PLC word defined in MP_cuttingSpeed.
Depending on the value entered in the PLC word defined in MP_spindleMode
for the spindle rotation, the PLC evaluates either MP_spindleSpeed (with
constant spindle speed = 96) or MP_cuttingSpeed (with constant cutting
speed = = 97).
If there are several spindles in an NC channel, you must enter in MP_type
which spindle the S strobe is to refer to.
The PLC checks the programmed spindle speed in addition. The result of this
check is saved in the PLC marker defined in MP_badSpeed. If the marker is
set, the spindle speed is outside the permissible range. If MP_badSpeed is
not defined, the spindle speed is not checked.
MP_type
If there are several spindles in an NC channel, you must enter
in MP_type which spindle the S strobe is to refer to.
Available from NCK software version: 597 110-01.
Format: Numerical value
Input: 0: S strobe refers to the main spindle
1: S strobe refers to spindle 1 (driven tool)
2: S strobe refers to spindle 2 (driven tool)
3: S strobe refers to opposing spindle
Default: 0
Access: LEVEL3
Reaction: RESET
MP_spindleSpeed
Symbolic name or number of the PLC word for transmitting the
spindle speed
Available from NCK software version: 597 110-01.
Format: String
Input: Name of the PLC word in which the spindle speed is
transmitted to the PLC
If the parameter is missing, the spindle speed cannot be read as
a numerical value.
Default: No value, parameter optional
Access: LEVEL3
Reaction: RESET
