AOP Applications

AOP Applications

NOTES:

1. If the AOP is the command source for the SED2, set USS Telegram Off Time for Serial

Interface BOP Link P2014[1]=5000 (5 seconds). To do this, first set P0003=3. The
P2014[1]=5000 setting causes the drive to trip if communications with the AOP control source
is lost.

2. If you have problems connecting to the SED2 drives, set the Auto Baud to OFF and the

default baud rate to the same as the SED2.

Single Drive Control Using the AOP

Per default, the AOP is configured to work with only one SED2 in Local mode. In Local mode, the
AOP normally mounts directly onto the SED2. The RS-232 and RS-485 ports handle
communications. Full operator control of the SED2 is available with access to all normal drive and
AOP internal parameters.

To configure a single SED2 VFD with the AOP as the control source, follow the procedure in the
Quick Commissioning section of this manual.

Network Setup (RS-485 with Panel Mounting Kit)

The AOP has the capability to control up to 31 SED2 VFDs connected as a network. In a network
configuration, a unique two-digit number identifies each VFD. When the AOP connects to a
network of SED2 VFDs, there are two Master Modes of operation:

• The AOP can access a single SED2 VFD on the network with full control/parameter access

• The AOP can use the Broadcast mode to simultaneously start/stop all drives on the network.

Use the following procedure to set up a network of SED2 VFDs under control of an AOP:

1. Use the standard panel mounting kit (PMK) to connect RS-485 communications as follows:

a. Correct wiring for PMK and SED2 VFD is as follows:

Pin 3 = +24V
Pin 4 = 0V
Pin 29 and 30 = RS-485 communications

b. Use twisted pair cable or shielded cable (preferred).
c. The end-of-line SED2 VFD must have a 120-ohm terminating resistor across RS-485

Pins 1 and 2.

d. Use a common ground for all SED2 VFDs and the PMK.
e. For the first issue of the PMK, for correct communications DIP Switch 1=UP or ON on

the PMK board.

Siemens Building Technologies 11

SED2 AOP Operating Instructions

2.

Configure the SED2 VFDs for network use.

a. Set the Command Source P0700[1]=5 (USS on Com link). This sets the control over the

USS link on the communications port.

b. Assign each drive a unique RS-485 USS address in the range of 0 to 30. To do this set

User Access Level P0003=3 (expert) and use USS Address for Serial Interface Com Link
P2011[0] to assign a unique address to each SED2 VFD.

c. If using the AOP as the normal control means for the SED2 VFD, it is recommended that

USS Telegram Off Time for Serial Interface BOP Link P2014[1]=5000. (To do this, first
set User Access Level P0003=3 [expert]). The P2014[1]=5000 setting causes the drive to
trip if communications with the AOP control source are lost.

3. With the SED2 VFDs powered-up on the network, connect and power-up the AOP on the

PMK.

4. On start-up of the AOP, select Mode from the main menu. Press to confirm the selection.

On display of the mode menu, select Master mode. Press

to confirm the selection. Press

to return to the main menu.

5. Select Operate from the main menu. The AOP lists all SED2 VFDs on the network. For each

connected SED2 VFD drive, an O appears (indicating normal operation).

NOTE: If there is a fault with a connected drive, an F appears (indicating a fault condition).

Network Setup (PC Mode)

The AOP can be configured as an RS-232 to RS-485 converter to allow a PC that is running
software to connect to a network of SED2 VFDs.

To use this configuration, use a null modem lead to connect the PC to the PMK. At the AOP main
menu, select Mode. At the mode menu, select PC Mode. Enter the desired baud rate of
operation.

Editing Parameters

Editing Parameters

Parameter Access Levels

You can edit SED2 VFD parameters via the AOP. Access leve ls control access to the SED2 VFD
parameters. A higher access level corresponds to a more sophisticated level of control
techniques available for the SED2 VFD applications. User Access Level parameter P0003 sets
the access level as follows:

• P0003=0 User Defined List

• P0003=1 Sta ndard Par ameters

• P0003=2 Extended Parameters

• P0003=3 Exper t Par ameters

The access level defined for a SED2 VFD (not the AOP) determines the access to the various
levels of parameters. Extended level parameters permit access to all Standard level parameters
as well as several others. Expert level parameters permit access to all Extended and Standard
level parameters, as well as indexed parameters. Parameter indexes provide subsets of a
particular parameter function. The indexes group together closely related parameter type
information.

Editing Conventional Parameters

NOTE: All parameters that are changed using the following procedures are changing the

physical parameters on the SED2 connected to the AOP.

AOP Stored Parameter Sets

The AOP contains a battery-backed storage facility for storing up to 10 parameter sets that are
identified numerically from 00 to 09.

Only a parameter set containing parameter data can be edited. If the selected parameter set does
not contain parameter data, the AOP asks if the default parameter set should be copied to the
selected parameter set. When you confirm this request, the AOP copies only the editable
parameters to the selected parameter set; read-only parameters are accessed from the original
parameter location.

Engineering

In Local mode, the AOP mounts directly onto one SED2 VFD
and then scans its RS-232 and RS-485 ports to establish
communications with the first port that answers. You can
control the SED2 VFD by accessing all normal SED2 and AOP
internal parameters. Local mode is the default of the AOP on
initial power-up or after a reset.

In Master mode, the AOP can control up to 31 SED2 VFDs
which connect in a multi-drop arrangement. An operator can
control each SED2 VFD by accessing all normal SED2 and
AOP internal parameters. In Master mode, the network
controls the SED2 VFDs either individually or by broadcast
operation. A broadcast operation can simultaneously start or
stop all networked SED2 VFDs.

In the Internal mode, you can access the stored parameter
sets in an AOP. You can not access any parameter sets stored
in the SED2 VFDs.
In the Internal mode, the main menu includes an Engineering
item. This menu item allows you to view a USS message log of
the last 1k bytes of messages between the AOP and the
connected SED2 VFDs.

In Slave mode, the AOP communicates with a PC using the
AOP Desk Mounting Kit. In this configuration, the AOP acts as
a slave to the PC. At the PC, you can upload and access
parameter sets or the AOP internal parameter set as a USS
address, numbered 1 through 10.

NOTES:

1. Before using the timer function as a control method, set the AOP real time clock as described
in the Set Time/Date section.

2. Setting a timing event for ‘every day’, configures the same event for each day of the week
separately. To clear an ‘every day’ event, you must clear the event individually from each
day.

3. When multiple events must be cleared from the Timer function, it may be easier to reset the
AOP as described in the AOP Reset section.

4. When in Master mode of operation and viewing the connected SED2 drives, a ‘T’ displays in
the top left corner to indicate that the connected SED2 drives are under timed remote control
and may start or stop unexpectedly.

Setting the AOP Timer

When in local or master mode, you can access the timer feature from the main menu. The timer
