MICROMASTER 411 & COMBIMASTER 411, AS-i Module Operating Instructions
6SE6400-5AT00-0BP0 9
1 Description
The AS-i Module (Actuator sensor-Interface Communications Module) has been
designed to control the COMBIMASTER 411 and MICROMASTER 411 inverters
via:
 ON/OFF commands
 Fixed frequency selection
 Reverse commands
 Fault acknowledge commands
In the standard AS-i system up to 31 slaves can be connected, each slave having
up to 4 input and output bits.
Without the use of repeaters or extenders the maximum length of a cable segment
in the network is 100 meters (328 feet).
The AS-i Module is connected to the network via the FK cable adapter on the lower
housing of the module casing by a simple two-wire cable without any shielding; this
cable supplies both the data path and power supply to the slave nodes
simultaneously.
Contact needles pierce the cable through the cable insulation and make contact
with the copper conductors. When the cable is removed from the cable adaptor the
outer insulation of the cable self-seals the holes made by the cable adaptor
needles.
Figure 1-1 on page 10 shows the general layout and connections of the AS-i
Module.

2 Installing the AS-i Module
WARNING
Make sure that the MICROMASTER 411/COMBIMASTER 411 inverter is isolated
from the electrical supply before you install or remove the AS-i Module.
CAUTION
 Do not knock out cable gland blanking plates unless inverter ‘electronics’ (Filter
& I/O boards) have been removed!
 The inverter and AS-i Module electronics contain static sensitive devices
therefore precautions must be taken against electrostatic discharge (ESD) when
handling the separated inverter assembly. These include not touching the
internal surfaces of the inverter and ensuring that personnel are earthed while
handling the unit. The terminal housing, including Filter and I/O modules,
contain no sensitive components and therefore no special handling precautions
are required when separated.

2.3 Addressing the AS-i Module
Before data transfer can take place between the AS-i Master and the slave devices
each slave must be assigned an address. The address of a AS-I slave can be
assigned using the following methods:
 Addressing off-line using the Siemens Addressing and Diagnosis Instrument
(Order Number: 3RK1904-2AB00)
 Addressing on-line using the controlling system, such as a PLC via the AS-i
Master (it should be noted that only one slave with address 0 may be present
on the bus if this method is to be implemented).
The addresses are designated numbers between 1 and 31, with each slave device
having a preset address of 0. If the AS-i master detects a slave with address 0, it
recognizes the device but does not integrate the device into the AS-i network.
The addresses of the slave devices do not have to be sequential, for example the
first slave device can have the address 21, the next 10.
The AS-I slave device has been designed with an external addressing connector
on the upper housing of the module to allow the connection of a dedicated
addressing unit. See Figure 2-10.

6SE6400-5AT00-0BP0 17
3 Commissioning
Time critical data should be sent over the AS-i bus in cyclic mode. Using this mode
data is sent reliably in a precisely defined time frame. Unfortunately, only 4 bits of
data can be sent to and received from the inverter in this manner.
3.1 Parameter settings
The following parameter descriptions are given to enable the user to control and
monitor the correct functioning of the AS-i slave module and the COMBIMASTER
411 / MICROMASTER 411. For parameterization you need either an Operator
panel (BOP or AOP) or a Commissioning software (DriveMonitor or Starter,
delivered with with the inverter).
Command Source and Setpoint Parameters
The following settings have to be performed in the COMBIMASTER 411 /
MICROMASTER 411 inverter:
Parameter Value Description
P0700 6 Command source is “CB on COM link”
P1000 3 Frequency setpoint is “Fixed Frequency”
P1020 P2091.0
Fixed frequency selection bit 0 source is “control word 2, bit 0
from CB”
P1021 P2091.1
Fixed frequency selection bit 1 source is “control word 2, bit 1
from CB”
P1022 P2091.2
Fixed frequency selection bit 2 source is “control word 2, bit 2
from CB”
NOTE
P0719 must be set to 0 (default) when BICO technology is used with "P0700" and
"P1000".
The fixed frequency modes bits have to be set to appropriate values, for example,
so that 7 independent fixed frequencies are used:
Parameter Value Description
P1016 3
Fixed frequency mode – bit 0 is “binary coded selection + ON
command”
P1017 3
Fixed frequency mode – bit 1 is “binary coded selection + ON
command”
P1018 3
Fixed frequency mode – bit 2 is “binary coded selection + ON
command”
Parameter P2040 (Telegram Failure Time) should be set to zero (0) if the function
is not required or to a value above 10 ms. Reasonable values are between 40 ms
to 100 ms.

The nibble sent to the inverter consists of three fixed frequency selection bits and
one forward-reverse/fault acknowledge bit.
The three FF selection bits map to the lowest three bits of control word 2. When
one or more of these bits are active then the inverter is started and bit 0 acts as a
forward or reverse bit.
When all three FF selection bits are inactive then the inverter is stopped and bit 0
acts as a fault acknowledgement bit.

Bit 3 is an inverter fault indicator. This is mapped from STW1 bit 3.
When bit 3 is inactive (no fault), bit 0 is the inverter running indicator mapped from
STW1 bit 2.
When bit 3 is active (fault), bit 0 is an AS-i fault acknowledge received indicator
(not mapped directly from the inverter).
Bits 1 and 2 are general purpose output bits. The function of these two bits are
controlled by P2041[0] and P2041[1] respectively. For this purpose the PZD is
mapped as a linear bit address space from STW1 bit 0 to bit 15 and the word
mapped to P2051.1 bit 0 to bit 15. The number written to P2041[0] and P2041[1]
controls which of these bits is mapped to bits 1 and 2 of the AS-i message from the
inverter.
NOTE
The PZD from the inverter is linked through P2051[0] to P2051[3].
Examples
1. Bit 1 should indicate status word 1 bit 11: motor current warning. (Bit 11 in
r0052)
To achieve this, set P2041[0] to 0 *16 + 11 = 11.
2. Bit 1 should indicate status word 2 bit 9: ramping finished. (Bit 09 in r0053)
To achieve this, set P2051[0] to 53 and P2041[0] to 0 *16 + 9 = 9.
3. Bit 2 should indicate the state of digital input 1.
To achieve this, set P2051[1] to 722. This maps r0722 (digital input states).
Now set P2041[1] to 1 *16 + 0 = 16.
NOTE
Bit 0 and Bit 3 are fixed.
Example 1 and 2 are mutually exclusive.
