Automatic Axis Replacement - Siemens SINUMERIK 840D sl Function Manual

Mode Groups, Channels, Axis Replacement (K5)
Axis/spindle replacement
Note
If the GET or GETD command has been programmed, take-over is delayed and the channel
is reset; the channel will no longer try to take over the axis.
An axis assumed with GET remains allocated to this channel even after a key RESET or
program RESET. The axis can be replaced by programming RELEASE and GET again or
will be assigned to the channel defined in the following machine data during POWER ON:
MD30550 $MA_AXCONF_ASSIGN_MASTER_CHAN
6.4.7

Automatic axis replacement

Automatically through programming of axis name
Depending on machine data MD30552 $MA_AUTO_GET_TYPE a GET or GETD is
generated automatically if a neutral axis is again programmed or assigned to another
channel.
Preconditions for automatic axis replacement
MD30552 $MA_AUTO_GET_TYPE > 0 must be true for automatic axis replacement.
Automatic GETD
Note
If an automatic GETD is set, the following must be observed:
• Channels could mutually influence each other.
• With simultaneous access of several channels to an axis it is not known which channel
Example 1
N1 M3 S1000
N2 RELEASE (SPI(1))
N3 S3000
