SIMODRIVE POSMO A User Manual (POS1) – 08/2013 Edition
5.5.12 Standalone mode (without bus communication) (from SW 1.2)
Safety signals, such as e.g. OFF1 are continually required. This
means, that when bus communications are interrupted, the motor is
immediately shut down with fault. This can be prevented using P100
(simulation of the control word).
!
Caution
In standalone mode, the drive is automatically reset in event of an
error, in other words:
The faults which occur are automatically acknowledged
Before SW 1.3 the following applies: The block sequence is
re–started
From SW 1.3, the following applies: The block sequence is
continued from the next
defined block
If the value of P100 is not equal to zero (e.g. 443F
hex
), when powering
up without a master or when the communication fails, after 3 seconds
the control word is replaced by this value.
The terminal signals remain active with the highest priority.
A maximum of ten traversing blocks in the range 3 to 27 can be preset
with SIMODRIVE POSMO A in P101:11 for the standalone mode.
These specified blocks are then processed consecutively in standalone
mode.
Rules when executing the blocks:
Execution sequence: from P101:1 to P101:10
If it is recognized that P101:x = 0, then the last block which is en-
tered is continuously repeated.
If the block lies within a program range, then the program is exe-
cuted, as programmed from this block.
The factory default setting for P101:11 is as follows (refer to Table 5-9):
