SINUMERIK 840Di sl Manual (HBIsl) – 01/2007 Edition
For each machine axis that a drive is to be assigned,
S
a setpoint channel and
S
at least one actual–value channel
must be parameterized.
A second actual–value channel can be set up as an option.
Notice
The motor measuring system is always used for the speed control function.
Motor and motor measuring system must therefore always be connected to the
same drive module.
In the two axis–specific machine data:
S
MD30110: CTRLOUT_MODULE_NR[0] (setpoint assignment: logic drive
number)
S
MD30220: ENC_MODUL_NR[n] (actual–value assignment: logic drive
number)
must always be entered the same logic drive number m of the drive represent-
ing the machine axis.
The input value m refers to the drive whose I/O address is defined under the
index n = (m–1) in MD13050: DRIVE_LOGIC_ADDRESS[n] (see Section
11.5.3, Page 11-314).
Once the drive configuration and setpoint/actual value assignment have been
parameterized, an NCK reset must be executed to initiate a warm restart. After
the NCK has booted, the new configuration becomes effective.
The interface signals
S
DB31, ... DBX1.5 (position measuring system 1 selected)
S
DB31, ... DBX1.6 (position measuring system 2 selected)
can be used to switch from the PLC between the two position measuring
systems of a machine axis.
