4.13 Configuration of axes − Handwheels
The control allows for the connection of electronic handwheels with CAN
interface. For this purpose, the handwheel must be configured in the
machine constants. Configure the handwheel analog to a normal axis.
The configured handwheels are consecutively numbered in the control from
0 ... N−1, while N corresponds to the maximum number of configurable
handwheels. Therefore, the assignment of an axis letter is optional and
generally not required.
The following machine constants must be set:
4.13.1 MK_CANDRIVES
This machine constant assigns application axis numbers to the node
numbers 1 ... 12 on the second CAN bus and thus defines which application
axes are configured. For each unassigned node number, enter value −1. The
axis letters are assigned to the specified application axis numbers via
MK_APPLACHSIDX.
4.13.2 MK_APPLACHSIDX
Assignment of a free axis letter for the configured handwheel. The
assignment of a letter is optional and only required if the handwheel or the
configured application axis channel is to be addressed via other G functions
as G187, e.g. home position approach with G74.
4.13.3 MK_ACHSENART
For the application axis assigned by MK_CANDRIVES, bit 7 must be set or
value 128 entered.
4.13.4 MK_IMPULSE
Number of pulses, which the handwheel provides per defined distance.
4.13.5 MK_WEG
Distance which an assigned axis should cover per number of pulses
(MK_IMPULSE) at an evaluation factor of 1.0. The direction can be changed
by changing the sign.
4.13.6 MK_HANDRADZUORDNUNG
This machine constant is an axis−specific MC which assigns a configured
handwheel to the individual axes. This MC has a parameter for each
application axis in which the number of the assigned handwheel is entered.
It must only be changed if more than one handwheel is configured. The
assignment can only be changed via this MC.
