General machine parameters
PROBEDEF (P168)
Defines the behavior of the probe.
This parameter has 16 bits counted from right to left.
Each bit has a function or work mode associated with it. By default, all the bits will be assigned the
value of ·0·. Assigning the value of ·1· activates the corresponding function.
Bit 0. Smooth stop of the probe (G75/G76).
This bit permits defining a smooth stop for probing moves (bit=1). When the probing pulse is
detected, the following error is not initialized, thus the probing move stops more smoothly.
When setting the smooth stop, axis parameter "DERGAIN (P25)" and spindle parameter "FFGAIN
(P25)" should be set to zero. This may be done by setting the set of gains through general parameter
"ACTGAIN2 (P108)" with the bit corresponding to G75/G76.
CANSPEED (P169)
CAN bus transmission speed for the digital drives.
The transmission speed depends on the length of the cable or total CAN connection distance.
For a speed of 1Mbit/s, the number of elements available at the CAN bus, depending on loop time,
will be:
Neither the fast channel nor the oscilloscope will be available in a configuration of LOOPTIME =
6ms and 6 elements at the bus.
FEEDTYPE (P170)
Behavior of the feedrate when programming F0.
If set to 0, F0 may be programmed and the motion blocks will be executed at the maximum feedrate
allowed.
If set to 0, it is not possible to program F0 or execute motion blocks with F0 active.
