Note
Because no frequency and no condition has been specified in the synchronized action, the
action part is executed in every interpolation cycle.
Synchronized actions

Meaning
: Number of the polynomial defined with
: Arbitrary system variable of the REAL type that can be used in
synchronized actions.
: Wear parameter (length 1, 2 or 3) in which the offset value is added.
: Target channel in which the offset must be applied. This enables
simultaneous dressing from a parallel channel. In the target channel
of the offset, the online offset must be switched on with
If no channel number is programmed, the offset acts in the active
: The spindle number is programmed if a non-active grinding wheel
channel.
needs to be dressed.
Requirement: One of the following functions is active
"Constant grinding wheel peripheral speed"
•
"Tool monitoring"
•
If no spindle number is programmed, the active tool is compensated.
Comment
; Synchronization with the machining channel
; Traversing motion of the V axis
; Deselect online offset
