■General Operation
Danger
Disassembly
prohibited
▼Never disassemble, modify or repair.
Doing so could result in electric shock, fire and injury. For repairs, call your sales agency.
Prohibited
▼Do not attach this option to any inverter other than the VF-AS1.
Doing so could result in electric shock or fire.
▼When the inverter is energized, never detach the this option from the VF-AS1.
Doing so could result in electric shock.
▼Don't place or insert any kind of object into the PDP002Z (electrical wire cuttings, rods,
wires).
Doing so could result in electric shock or fire.
▼Do not allow water or any other fluid to come in contact with the PDP002Z.
Doing so could result in electric shock or fire.
Mandatory
▼Turn off the VF-AS1 when installing and wiring the terminal block.
▼If the inverter begins to emit smoke or an unusual odor, or unusual sounds, immediately
turn power off.
If the equipment is continued in operation in such a state, the result may be fire. Call your
local sales agency for repairs.
■Transportation & installation
Danger
Prohibited
▼Do not operate the inverter if it is damaged or any component is missing.
Doing so could result in electric shock or fire. Call your local sales agency for repairs.
▼Do not place any inflammable substances near the VF-AS1 Inverter.
If an accident occurs in which flame is emitted, this could lead to fire.
▼Do not install in any locationwhere the inverter could come into contact withwater or other
fluids.
Doing so could result in electric shock or fire.
▼When installing this option, be careful not to touchthe leads from parts on the reverse side
of its circuit board.
Doing so could result in injury.
Mandatory

■Wiring
Danger
Mandatory
▼Shut off power when installing and wiring this option.
Wait at least 15 minutes and check to make sure that the charge lamp (VF-AS1) is no
longer lit.
▼Electrical construction work must be done by a qualified expert.
Installation or connection of input power by someone who does not have that expert
knowledge may result in fire or electric shock.
■Operations
Danger
Prohibited
▼Do not touch switches when the hands are wet and do not try to clean the inverter with a
damp cloth.
Doing so could result in electric shock.
▼Do not pull on any cable itself.
Doing so could result in damage or malfunction.
■Disposal
Warning
Mandatory
▼For safety's sake, do not dispose of the disused inverter yourself but ask an industrial
waste disposal agent (*).
If the collection, transport and disposal of industrial waste is done by someone who is not
licensed for that job, it is a punishable violationof the law. (Laws in regard to cleaning and
processing of waste materials)
(*) Persons who specialize in the processing of waste and known as “industrial waste
product collectors and transporters” or “industrial waste disposal persons.”
Notes on use
Notes
▼Do not install the inverter where the temperature or the humidity will change rapidly.
▼Keep a distance of 20cm or more between the inverter's power cable and the data
transmission cable.
Or the inverter might malfunction because of noise.
▼Insert a magnetic contactor or similar device betweenthe inverter and the power supply to
ensure that power is turned off if an emergency stop command is entered through the
network.

Introduction
Thank you for purchasing a “VF-AS1 PROFIBUS Option (PDP002Z),” for TOSVERT VF-AS1
inverter. Installing this option in the VF-AS1 and using it together, data communication can be
made with a host computer or other device via PROFIBUS DP (DP-V0). Please read the entire
manual carefully before attempting to control your inverter via PROFIBUS connection.
Besides this instruction manual, the “PDP002Z Function Manual” is required to develop the
software of communication with VF-AS1. In such a case, please get in touch with our branch
offices or sales offices. (“PDP002Z Function Manual”: E6581343).

1.Overview
The PDP002Z option allows the VF-AS1 inverter to be connected as a slave (DP-V0) into a
PROFIBUS network. Up to 126 stations* can be connected to the network (* including a
master. If no repeater is provided, up to 32 stations can be connected to each segment).

2.1. PROFIBUS connector
Used to connect PROFIBUS network cables. The connector is a D-Sub connector with 9 pin
female and the connector pin allocation described below follows the PROFIBUS standard.
The PDP002Z has no termination resistor. Therefore, termination resistors need to be
connected to the station on each side of the PROFIBUS network or the master, as shown in
the figure below. (The PROFIBUS connector with termination resistor are recommended.)
2.2. Status indicator
The PDP002Z has two LEDs, ST (status) and DX (data exchange) to indicate the
statuses of PROFIBUS-DP and the PDP002Z itself.
ST (Status): Red LED

3.Installing the PDP002Z
Install the PROFIBUS option to VF-AS1 as follows:
* When this option is used together with the IO card option, attach this option to the front
panel side.
(1) Turn off input power of VF-AS1 and wait for at least 15 minutes and then check that the
CHARGE lamp on VF-AS1 is no longer lit.
(2) Securing the option to the inverter
a) Insert a flat-blade screwdriver in each of the two holes at the upper part of the front
panel, release the panel mounting tab by pushing the screwdriver down, and remove
the front panel cover.
b) Install the option in the inverter by fitting the tabs on the lower side of the option into
the slots at the lower part of the inverter front panel.
c) Make sure the option is securely attached to the inverter. Then, check whether the
plastic bosses on the inverter case have fitted in the holes at the upper and lower
parts of the option.
d) Insert the tabs at the lower part of the front cover into the slots at the lower part of
the inverter to attach the front cover to the inverter.

4.Connecting to the network
4.1. Installation method
(1) Using the DIP switch on the PROFIBUS option, set a station address (Refer to Section
4.2).
(2) Connect a PROFIBUS connector to the PDP002Z. (Refer to Section 2.1.)
* If the PDP002Z is located at an end of the bus, connect a terminal resistor to it. (When
using a connector with termination resistor, set it ON.)
(3) Once all the parameters are set, the power must be cycled to the VF-AS1 for these
changes to take effect. (Refer to Section 5.)

4.2. Setting a station address
The DIP switch onthe circuit board of the option is used to set a station address. EachDIP
switch is ON when it is flipped to the lower position. By default, it is factory-configured to 2.
The station address must be unique and not match any other device on the network.

5.1. f851: Communication Loss Action Setting (Network breaks)
This parameter sets up the VF-AS1 response to a loss of communications with the
PROFIBUS network.
0: Stop and break of connection
The inverter decelerates the motor to a stop and gives the alarm.
Commands entered through the network are canceled, and the commands set with
parameters cmod and fmod become effective.
When communications are restored, the alarm is turned off.
1: None
The inverter remains inthe state where it was whenthe problem arose, and it gives the 
alarm.
2: Deceleration stop
The inverter decelerates the motor to a stop and gives the alarm. Commands entered
through the network are not canceled.
3: Coast stop
The inverter issues a command for a frequency of 0Hz and gives the alarm. Commands
entered through the network are not canceled.
4: Emergency stop
The error message err8 is displayed. Commands entered through the network are
not canceled.
When communications are restored, the inverter is not restored to working order and the
error message err8 does not disappear until the inverter is reset.
5: Preset speed operation command
Refer to Section 5.2
5.2. f852: Preset speed operation selection
If the communication loss action (parameter f851) is set to 5 (preset speed command),
the VF-AS1 will run at a preset speed as set up by this parameter in the case of a
communication loss (withalarm). Commands entered throughthe networkarenot canceled.
For example,
If the inverter is set as described below,
f851 = 5 (preset speed operation command)
f852 = 8 (preset speed operation frequency 8)
f287 (preset speed operation frequency 8) = 10 (10Hz)
Operation is carried out as follows.
Network Operation of the VF-AS1
Normal conditions........... Operates according to commands entered through the network.
↓ ↓
communications loss ...... Operates at 10Hz.
