Exchange Of Signals With Masterdrive Fc / Vc / Sc From 1995 - Siemens SIMOVERT FC Series Operating Instructions Manual

Function Descriptions
3.9 Exchange of signals with MASTERDRIVES FC / VC / SC from 1995
The data exchange with the basic unit takes place via a high-speed DUAL PORT RAM located on the T100 (see
sheet 1 of block diagram). A maximum of 10 values in the actual value area can be transferred at a time from the
basic unit to the T100 and in the setpoint area from the T100 to the basic unit. The connection of these data -
both in the basic unit and in the T100 - is shown on sheets 10 ... 14 of the block diagram.
Note: Pages 10 ... 14 of the block diagram show the process data exchange with the Master Drives FC, VC
and SC in the version available in July 1995. Please consult the Operating Instructions of your Master
Drives basic unit for details of the process data interface between the basic unit and technology board
("TB") which is currently available. The connection of process data exchanged with the T100 in the
Master Drives infeed/regenerative feedback units is not shown in the diagram. These connections must
be made on the same basis as the mechanisms described in this manual in accordance with the
operating instructions of the input/regenerative feedback unit used.
Actual value area (signals from basic unit ⇒ T100)
It is possible to link any signals (defined as non-indexed r or P parameters) of the basic unit to the words in the
actual value area by means of P694.01...10.
Example: - Basic unit is a MASTER DRIVE VC
- The actual frequency value r218 must be linked to the T100 in word 2 of the actual value area
- ⇒ Set P694.2=218!
- The actual frequency value is available in K038
It is advisable to link status words 1 and 2 (r968 and r553) to words 1 and 4 of the actual value area by setting
P694.1=968 and P694.4=553.
Before the basic unit actual values can be processed on the T100, they must be converted to the internal
"connector format" (100% = 4000 Hex = 16384 Dec). For "PZD groups" 2 to 4, this conversion involves a
multiplication by 4 and the connector which has the multiplier "∗4" at its input should be selected to process the
actual values.
Example:- The basic units is a MASTER DRIVE VC with "Closed-loop speed control" method
- The converter output current r004 must be connected to the T100 in word 9 of the actual value area.
r004 has numerical notation "100% equals 1000 Hex"
- ⇒ Set P964.9=004
- The output current is available in K052 in the normal connector representation "100% equals
4000 Hex"
Status bits from basic unit (sheets 13 and 14 of block diagram)
There are 32 basic unit status bits available as binectors for further processing on the T100. All status bits can be
viewed in d030.01 and d030.02. A luminous bar is assigned to each status bit on the 7-segment display of the
PMU operator panel.
Setpoint area (signals T100 ⇒ basic unit)
The setpoints and control bits which the T100 sends to the basic unit are only effective in the unit if they are
gated there via the injection or connection parameters specified on sheets 10 ... 12 of the block diagram. There
is, however, one exception:
Important: If a T100 is logged on with the basic unit (P090=2), then control bit 10 "Control requested" is always
connected to the basic unit (sheet 11 of block diagram). It is essential to set this control bit 10 to "1"
on the T100 - e.g. via H272.11 = 1 if the basic unit must accept setpoints and control commands from
the T100.
