SIMODRIVE 611 universal Description of Functions (FBU) – 04.05 Edition
Depending on a condition, the position in traversing block 4 (P0081:3)
should be adapted as required via PROFIBUS.
In this particular example, P0081:3 = 14 586 is written.
Assumptions for the slave:
The drive has been completely commissioned is connected to
PROFIBUS–DP and is ready to run.
P0700 = 3 (”positioning” mode) has been set
P0918 = 12 (PROFIBUS node address) has been set
Assumptions for the master:
The DP master is a SIMATIC S7 (CPU: S7–315–2–DP)
Hardware configuration
– 1–axis, PPO type 1, node address = 12
– Part I address O address
PKW 272 – 279 272 – 279
PZD 280 – 283 280 – 283 (not shown in the example)
If the condition to write the position in traversing block 4 is available,
then the following must occur on the master side
(refer to Fig. 5-21):
1. Write the parameter value (define task)
– PKW output signals (PAB 272 – 279) written into
with
AK = 8, PNU = 81, IND = 3, PWE2 = 14586
2. Check the task
– Evaluate the PKW input signals (PEB 272 –279)
– If AK = 5, PNU = 81, IND = 3 and PWE2 = 14586 then OK
– If AK = 7,
then evaluate the fault number in PEW 278 (refer to Table 5-31)
