SIMODRIVE POSMO A User Manual (POS1) – 08.03 Edition
5.5 SIMODRIVE POSMO A functions
5.5.12 Standalone mode (without bus communications) (from SW 1.2)
Description
!
Setting the
standalone mode
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 the standalone mode, when a fault develops, the drive is
automatically reset, i.e. the following applies:
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. 443Fhex), 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.
For SIMODRIVE POSMO A in the standalone mode, a maximum of 10
traversing blocks can be entered into P101:11 in the range from 3 to
27. In the standalone mode, these specified blocks are executed one
after the other.
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
entered is continuously repeated.
If the block lies within a program range, then the program is executed,
as programmed from this block.
The factory default for P101:11 is as follows (refer to Table 5-9):
Table 5-9 P101:11 (block sequence in the standalone mode)
(factory default)
P101:11
