Constraints
For a coupling module speed coupling cannot be activated simultaneously with setpoint or
actual value coupling of another leading axis.
5.5.5.3

Co-ordinate reference (CPFRS):

The co-ordinate reference of the following axis/spindle specifies in which co-ordinate
reference system the coupling component resulting from the coupling is applied. in the base
co-ordinate system or in the machine co-ordinate system.
It is further specified which co-ordinate reference the leading values of the leading axis
spindle must have. When a transformation is active and when the machine co-ordinate
system is specified as co-ordinate reference (CPFRS="MCS"), the initial transformation values
are taken as leading values.

CPLSETVAL[FAx,LAx]= <value>
Coupling Lead Set Value
Defines tapping of the leading axis/spindle LAx and the reaction
point on the following axis/spindle FAx.
Type: STRING
Range of values:
"CMDPOS" Commanded Position
"CMDVEL" Commanded Velocity
"ACTPOS" Actual Value
Default value: "CMDPOS"
Setpoint value
coupling
Speed coupling
Actual value coupling
Comment
; The coupling of following axis X2 to leading
axis X1 is deducted from the setpoint.
