Link axis drive information

You can access the drive data via the machine axis identifier, even if the axis is being
applied to another NCU. The following system variables of the drive with machine axis
identifiers [n] (previously only channel axis identifiers) can be used:
● $AA_LOAD[n], $VA_LOAD[n]
● $AA_TORQUE[n], VA_TORQUE[n]
● $AA_POWER[n], $VA_POWER[n]
● $AA_CURR[n], $VA_CURR[n]
● $VA_VALVELIFT[n]
● $VA_PRESSURE_A[n]
● $VA_PRESSURE_B[n]
The following section describes how to query the drive status of link axes by means of these
system variables and static synchronized actions.
