SIMODRIVE 611 Planning Guide (PJU) – 05.01 Edition
An analog axis can essentially be used the same as a digital axis. It can be
programmed just like a digital interpolating path axis or spindle. Or course, it is
not possible to use the pure functions of the digital drive unit with a coupling via
the analog speed setpoint interface. It involves a functionality which accesses
the internal axis feedback loops and communications via the drive bus, e.g.
SINUMERIK Safety Integrated. Separate EMC measures should also be
provided, where necessary, for the external drive devices.
Using SINUMERIK 840D, it is possible to operate a maximum of two analog
axes on the digital drive bus via the ANA configuration. It is also possible to use
an HLA and an ANA axis together.
2.6.10 NCU box for SINUMERIK 840D
If digital drive modules are used in conjunction with the SINUMERIK 840D CNC
control, then the NCU box can be located directly to the right of the infeed mo-
dule.
