SIMOVERT MASTERDRIVES
The following conventions apply to all parameters with index (e.g.
P918.x) given below:
♦ Index 1 is valid for the first CBP
♦ Index 2 is valid for the second CBP
To determine which CBP is the first and which the second, see Section
8.2.5 "Mounting methods / CBP slots".
P053 (parameter access)
This parameter is significant for the CBP if you wish to set or change
parameters of the converter (including technology) by means of the PKW part
of the PROFIBUS telegrams.
In this case, please set parameter P053 to an uneven number (e.g. 1, 3, 7
etc.). With parameter P053, you can define the positions (PMU, CBP etc.)
from which parameters may be altered.
Example: P053 = 1: Parameter access only CBP
= 3: Parameter access CBP+PMU
= 7: Parameter access CBP+PMU+SCom1 (OP)
If changing parameters (= parameter access) has been enabled via the CBP
(P053 = 1, 3 etc.), all other parameter settings can be made from the
PROFIBUS-DP master via the bus.
For the additional setting of parameters which concern data transfer via the
PROFIBUS-DP (e.g. process data (PZD) combination), you must know the
PPO type used for the transfer of useful data.
P060
Function selection "Hardware setting"
P090 (board position 2) or P091 (board position 3)
You can also change these parameters if the CBP exchanges useful data via
the PROFIBUS-DP. In this way, you can isolate the PROFIBUS-DP interface
from the converter with the appropriate parameterization. In this case, the
CBP changes over to the PROFIBUS-DP status "Static Diagnosis", i.e. the
CBP causes the PROFIBUS-DP master to exit the data-exchange mode and
only to request diagnostic telegrams from the CBP.
P918.x (CBP Bus Address)
The bus address set in parameter P918 is not accepted until P060 has been
changed from "5" to "7". If the address is changed after the CBP has been
parameterized, fault F080 will be output.
An address change only becomes effective after the power supply to the
electronics box has been turned off and then turned on again!
