1. SAFETY

This manual contains clearly marked cautions and warnings that are intended for your personal safety and to avoid any unintentional damage to the product or connected appliances.

Please read the information included in cautions and warnings carefully.

The cautions and warnings are marked as follows:

Table 1. Warning signs

= DANGER! Dangerous voltage

= WARNING or CAUTION

= Caution! Hot surface

1.1 Danger

The components of the power unit are live when the drive is connected to mains potential. Coming into contact with this voltage is extremely dangerous and may cause death or severe injury.

The motor terminals U, V, W and the brake resistor terminals are live when the AC drive is connected to mains, even if the motor is not running.

After disconnecting the AC drive from the mains, wait until the indicators on the keypad go out (if no keypad is attached, see the indicators on the cover). Wait 5 more minutes before doing any work on the connections of the drive. Do not open the cover before this time has expired. After expiration of this time, use a measuring equipment to absolutely ensure that no

absence of voltage before starting any electrical work!

The control I/O-terminals are isolated from the mains potential. However, the relay outputs and other I/O-terminals may have a dangerous control voltage present even when the AC drive is disconnected from mains.

voltage is present.

Always ensure

Before connecting the AC drive to mains make sure that the front and cable covers of the drive are closed.

During a ramp stop (see the Application Manual), the motor is still generating voltage to the drive. Therefore, do not touch the components of the AC drive before the motor has completely stopped. Wait until the indicators on the keypad go out (if no keypad is attached, see the indicators on the cover). Wait additional 5 minutes before starting any work on the drive.

13006.emf

1.2 Warnings

The AC drive is meant for fixed installations only.

Do not perform any measurements when the AC drive is connected to the mains.

The earth leakage current of the AC drives exceeds 3.5mA AC. According to stan- dard EN61800-5-1, a reinforced protective ground connection must be ensured. See Chapter 1.3.

If the AC drive is used as a part of a machine, the machine manufacturer is responsible for providing the machine with a supply disconnecting device (EN 60204-1).

Only spare parts delivered by VACON

can be used.

At power-up, power break or fault reset the motor will start immediately if the start signal is active, unless the pulse control for

Start/Stop logic has been selected Furthermore, the I/O functionalities (including start inputs) may change if parameters, applications or software are changed. Disconnect, therefore, the motor if an unexpected start can cause danger.

The motor starts automatically after automatic fault reset if the auto restart function is activated. See the Application Manual for more detailed information.

Prior to measurements on the motor or the motor cable, disconnect the motor cable from the AC drive.

Do not touch the components on the circuit boards. Static voltage discharge may damage the components.

Check that the EMC level of the AC drive corresponds to the requirements of your supply network.

Wear protective gloves when you do mounting, cabling or maintenance operations. There can be sharp edges in the AC drive that can cause cuts.

1.3 Earthing and earth fault protection

CAUTION!

The AC drive must always be earthed with an earthing conductor connected to the earthing terminal marked with .

The earth leakage current of the drive exceeds 3.5mA AC. According to EN61800-5-1, one or more of the following conditions for the associated protective circuit must be satisfied:

a) The protective conductor must have a cross-sectional area of at least 10 mm2 Cu or 16

mm2 Al, through its total run.

b) Where the protective conductor has a cross-sectional area of less than 10 mm2 Cu or 16

mm2 Al, a second protective conductor of at least the same cross-sectional area must be provided up to a point where the protective conductor has a cross-sectional area not less than 10 mm2 Cu or 16 mm2 Al.

c) Automatic disconnection of the supply in case of loss of continuity of the protective conduc-

tor.

The cross-sectional area of every protective earthing conductor which does not form part of the supply cable or cable enclosure must, in any case, be not less than:

-2.5mm

-4mm

if mechanical protection is provided or

if mechanical protection is not provided.

The earth fault protection inside the AC drive protects only the drive itself against earth faults in the motor or the motor cable. It is not intended for personal safety.

Due to the high capacitive currents present in the AC drive, fault current protective switches may not function properly.

Do not perform any voltage withstand tests on any part of the AC drive. There is a certain procedure according to which the tests must be performed. Ignoring this procedure may result in damaged product.

2. BACNET - GENERAL INFO

BACnet stands for ‘Building Automation and Control Networks’. It is the common name for the communication standard ISO 16484-5 which defines the methods and the protocol for cooperating building automation devices to communicate. Devices can be designed to operate using BACnet communication protocol as well as utilising BACnet protocol to communicate between systems. BACnet is an internationally accepted protocol for building automation (e.g. lightning control, air conditioning and heating automation) and control over a communications network.

BACnet provides a method by which computer-based control equipment, from different manufacturers can work together, or 'interoperate'. For this to be achieved, components must be able to exchange and understand BACnet data messages.

Your VACON

100 family AC drive is equipped with BACnet support as standard.

3.3 ACD (Address Conflict Detection)

The VACON® 100 family AC drives implement the ACD algorithm (IETF RFC 5227).

The ACD algorithm tries to actively detect if the IP address configured to this device is been used by another device in the same network. To accomplish this, ACD sends four ARP request packets when the device's Ethernet interface goes up or when its IP address changes. ACD prevents the use of the Ethernet interface until the ARP probing finishes. This delays the startup of fieldbus protocols about one second. During the delay or after it, the ACD passively checks incoming ARP messages for use of the device's IP address.

If another device with the same IP address is detected, the ACD will try to defend its IP address with a single ARP message. If the other device with the same IP address also supports ACD, it should stop using the address. If not, the ACD will close the Ethernet connection and indicate the situation with an Alarm. This is done according the "DefendWithPolicyB". Acknowledging of the Alarm is not possible if the problem is active. ACD opens Ethernet connection if the other device with the same IP address disappears from the network. Alarm can be acknowledged after this. Other policies are not supported. If the fieldbus protocol has been active, a fieldbus fault may be activated (depends on the fieldbus and drive application configuration).

4.3 BACnet MS/TP parameter descriptions

4.3.1 BACnet MS/TP Parameters

P5.8.3.1.1 BAUD RATE

Select the communication speed for the network. The default value is 9600 baud. If Autobauding is selected, the node will detect the baudrate. There must be at least one device in the bus to select the baud rate and to start token transmitting. When the baudrate is detected, it is saved into this parameter.

NOTE! Autobauding is disabled after baudrate is detected.

P5.8.3.1.2 MAC ADDRESS

The parameters of every device must be set before connecting to the bus. Especially the parameters

The first parameter, BACnet MAC (Medium Access Control) address, must be unique on the network to which it is connected. The same MAC address may be used on a device on another network within the internetwork.

Addresses 128-254 are reserved for slaves. Addresses 1-127 are valid for both masters and slaves. The portion of the address space that is actually used for masters in a particular installation is determined by the value of the Max_Master property of the Device object.

MAC address and Baud rate must be the same as in the master’s configuration.

It is recommended that MAC address 0 be reserved for use by the MS/TP router. 255 is reserved for broadcasts.

P5.8.3.1.3 INSTANCE NUMBER

The Device Object's Instance number must be unique across the entire BACnet internetwork because it is used to uniquely identify the BACnet devices. It may be used to conveniently identify the BACnet device from other devices during installation.

If 0 (default) is selected, the Device Instance number is generated from the last 22 bit of the Ethernet MAC address. This unique number is then shown in the Monitor menu (actual instance).

P5.8.3.1.4 MAXMASTER

This parameter defines the last possible master on the network segment. Each master node is responsible for searching new devices from network using the ‘poll for master’ messages. The nodes are searched up to MAC address defined by MaxMaster parameter.

This parameter affects the cycle time of the token. We recommend to use the highest MAC address value in the network for this parameter.

P5.8.3.1.5 COMMUNICATION TIMEOUT

The BACnet MS/TP indicates timeout error if the node is not receiving a token within time defined by this parameter. It can be used to detect communication loss to other nodes. Time unit is seconds.

NOTE! Application parameter P3.9.1.6 (ID 733) can be use to define action for communication timeout.

Local contacts: http://drives.danfoss.com/danfoss-drives/local-contacts/

vacon • 12 Programming

P5.8.3.1.6 MAXAPDUCYCLE

This parameter defines the maximum time in seconds between APDU messages addressed to this node. The APDU messages are Application layer messages, for example, 'ReadParameter' and 'Write Parameter' messages. This can be used to detect communication loss to the controlling node.

NOTE! The application parameter P3.9.1.6 (ID 733) can be used to define the action for communication timeout.

4.3.2 BACnet MS/TP monitoring values

V5.8.3.2.1 FIELDBUS PROTOCOL STATUS

Fieldbus Protocol Status tells the status of the protocol.

V5.8.3.2.2 COMMUNICATION STATUS

The Communication status shows how many error and how many good messages the AC drive has received. The Communication status includes a common error counter that counts CRC and parity errors and a counter for good messages.

Only messages to the current slave in use are counted in the good messages, not MS/TP token packages.

V5.8.3.2.5 UARTDBG

This is advanced debug information from RS-485 uart module. It shows parity, framing and overrun errors occurred while receiving the MSTP messages.

V5.8.3.2.6 ACTIVECOVCOUNT

This shows the number of active COV subscriptions on the device.

V5.8.3.2.7 CONTROL WORD
