Reference is made exclusively to the transverse axis of the channel.Axis-specific diameter programming for several transverse axes in one channelNoteThe additionally specified axis must be activated via MD30460$MA_BASE_FUNCTION_MASK with bit 2 = 1.The axis specified must be a known axis in the channel. Geometry, channel or machine axesare permitted.Programming is not permitted in synchronized actions.The following axis-specific modal statements can be programmed several times in a partprogram block:● DIAMONA[]: Diameter programming for G90, G91, AC and IC ON● DIAMOFA[]: Diameter programming OFF, in other words, radius programming ON● DIAM90A[]: Diameter or radius programming depending on the reference mode:– Diameter programming ON in connection with absolute dimensioning G90 and AC– Radius programming ON in connection with incremental dimensioning G91 and IC● DIACYCOFA[Axis]: Radius programming for G90 and G91 ON, for the HMI, the lastactive G command of this group remains active● DIAMCHANA[Axis]: Acceptance of diameter programming channel status● DIAMCHAN: All axes with MD30460, bit 2 = 1 accept the diameter programming channelstatusAxis-specific modal statements have priority over the channel setting.4.4 Supplementary conditionsAxis interchangeDue to a GET request from the parts program, the diameter programming status for anadditional transverse axis is accepted in the new channel during axis replacementusing RELEASE[].Axis interchange in synchronized actionsFor axis replacement in synchronized actions, a transverse axis takes the status of the axis-specific diameter programming with it into the new channel if:● with MD30460, bit 2 = 1 axis-specific diameter programming is permitted for the transverseaxis.● the transverse axis is not subordinated to the channel-specific diameter programming in thereleasing channel.The active dimension can be queried via the system variable $AA_DIAM_STAT[].P1: Transverse axes4.4 Supplementary conditionsAxes and spindles122 Function Manual, 06/2019, A5E47437747B AA
