5.4 Axis/spindle replacement
5.4.1 Introduction
General information
An axis/a spindle is permanently assigned to a specific channel via machine data. The
axis/spindle can be used in this channel only.
Definition
With the function "Axis or spindle replacement" it is possible to enable an axis or a spindle
and to allocate it to another channel, that means to replace the axis/spindle.
Since the spindle function is subordinated to the axis function, only the term "Axis
replacement" is used in the following.
Axis types
According to the channel, we distinguish four types of axes: The reactions at axis change
depend on the settings in MD 30552:
MD30552 $MA_AUTO_GET_TYPE
Channel axis
A channel axis can be programmed in the part program and traversed in all modes.
PLC axis
A PLC axis can only be positioned via the PLC.
If a PLC axis is programmed in the part program
● in case of MD AUTO_GET_TYPE = 0 an alarm will be output.
● in case of MD AUTO_GET_TYPE = 1 an automatic GET will be generated.
● in case of MD AUTO_GET_TYPE = 2 an automatic GETD will be generated.
Neutral axis
If a neutral axis is programmed in the part program
● in case of MD AUTO_GET_TYPE = 0 an alarm will be output.
● in case of MD AUTO_GET_TYPE = 1 an automatic GET will be generated.
● in case of MD AUTO_GET_TYPE = 2 an automatic GETD will be generated.
