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:
= 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
ensure 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.
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.
voltage is present.
Always

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 standard 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 the manufacturer 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:
0) The protective conductor must have a cross-sectional area of at least 10 mm Al, through its total run.
a) Where the protective conductor has a cross-sectional area of less than 10 mm
2
Al, a second protective conductor of at least the same cross-sectional area must be

Cu or 16 mm2 Al.
b) Automatic disconnection of the supply in case of loss of continuity of the protective
conductor.
2
Cu or 1 6 mm2
2
Cu or 16
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
2
if mechanical protection is provided or
2
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 can cause damage to the product.

CANopen option board OPTE6 - General vacon • 9

2. CANOPEN OPTION BOARD OPTE6 - GENERAL

2.1 Overview

OPTE6 is a CANopen adapter board for VACON® AC drives. The board allows the AC drive to be controlled by using the CANopen protocol. The board implements the AC drive profile with the velocity mode.
The option board firmware implements the following protocol specifications:
• CiA-301 CANopen communication specification version 4.2
• CiA-402 CANopen Profile for Drives and Motion Controller version 3.2
Device: AC drive
Operation mode: velocity mode
• CiA-303-3 CANopen indicator specification, implemented by using 2 CANopen status led indicators

2.2 Software

2.2.1 CAN

The CAN data link layer protocol is standardised in ISO 11898. The standard describes mainly the data link layer composed of the logical link control (LLC) sub layer and the media access control (MAC) sub layer, and some aspects of the physical layer of the OSI reference model.

2.2.2 CANopen

CANopen is an application layer protocol on top of the CAN bus.
The protocol specification describes:
• Set of bit rates to support
• Network Management (NMT)
• Service data transmission (SDO)
• Process data transmission (PDO)
• Error message transmission (EMCY)
• Node status monitoring (heartbeat and node guarding)
• Identity information
• Parameter saving and restoring

3. CANOPEN PROTOCOL DESCRIPTION

3.1 NMT

NMT network management manages CANopen, and is a mandatory, common feature for all devices. The protocol describes several node control services and the state machine.
1 = When the power is on, the NMT state is entered autonomously
2= The NMT state initialisation is finished, the NMT pre-operational state is entered automatically
3 = NMT service starts with remote node indication or by local control
4 and 7 = NMT service enters pre-operational indication
5 and 8 = NMT service stops remote node indication
6 = NMT service starts remote node indication
9, 10 and 11 = NMT resets node indication
12, 13 and 14 = Indication of NMT service reset communication
Boot-up protocol
After a node starts, it will enter automatically into the pre-operational state. Always when this transition occurs, a boot-up message is sent into the bus.

3.2 Node control protocols

Protocol start remote node
The start remote node message sets the node(s) into operational state. See Figure 1. NMT state machine. If the node ID in the message is set to ‘0’, the message affects all nodes (broadcast).
Table 2: Start remote node message

0x0 0x2 0x1
NODE ID
Protocol stop remote node
The stop remote node message sets the node(s) into stopped state. See Figure 1 NMT state machine. If the node ID in the message is set to ‘0’, the message affects all nodes (broadcast). When the node is in stopped state, it will not answer to SDO or PDO messages.
Table 3: Stop remote node message
CAN ID LENGTH DATA0 DATA1 DATA2 DATA3 DATA4 DATA5 DATA6 DATA7
0x0 0x2 0x2
NODE ID
Protocol enter pre-operational
The enter pre-operational message sets the node(s) into pre-operational state. See Figure 1. NMT state machine. If the node ID in the message is set to ‘0’, the message affects all nodes (broadcast). When the node is in pre-operational state, it will not answer to PDO messages.
Table 4: Enter pre-operational message

NODE ID
Protocol reset node
The reset node message makes the node(s) apply application reset. See Figure 1. NMT state machine. Application reset sets the whole object dictionary back to the default or previously saved values. If the node ID in the message is set to ‘0’, the message affects all nodes (broadcast). After the node has made the application reset, it will enter the pre-operational state automatically from the initialising state. This also creates a boot-up event and the boot-up message is sent after the reset.

vacon • 12 CANopen protocol description
Protocol reset communication
The reset communication message makes the node(s) apply communication reset. See Figure 1. NMT state machine. Communication reset does not affect the object dictionary values. If the node ID in the message is set to ‘0’, the message affects all nodes (broadcast). After the node has made the communication reset, it will enter the pre-operational state automatically from the initialising state. This also creates a boot-up event and the boot-up message is sent after the reset.

3.3 Error control protocols

It is not allowed to use guarding protocol and heartbeat protocol on one NMT slave at the same time. If the heartbeat producer time is unequal 0, the heartbeat protocol is used.

3.3.1 Heartbeat protocol

Heartbeat protocol defines the producer and consumer. The producer node sends its NMT status that is then available for any consumer node. The consumer node is the receiver of heartbeat messages. The producer node has a timing parameter that indicates how often the heartbeat message should be sent. The consumer node has a relative parameter that indicates how often the heartbeat message should be received. If the consumer does not receive the heartbeat message within the time defined in the heartbeat object entry, an error event occurs.

3.3.2 Node guarding protocol

Node guarding protocol is a NMT master driver protocol, where the master sends a remote transmission request, which is answered by the slave. The slave response includes one data byte that consists of a NMT slave state, and a toggle bit that toggles every response.
NOTE! The CiA application note 802 recommends that the node guarding protocol should not be used, because of different handling of RTR frames in CAN controllers.
OPTE6 option board does not have a hardware-triggered automatic response to the RTR frame. RTR information is handled by software, and the response data always consists of updated information.

3.3.3 EMCY object

Option board works as an EMCY producer. The EMCY object is transmitted when a fault occurs in the drive or option board. To switch off the EMCY producer, disable the EMCY COB-id by writing MSB to 1 (object 0x1014).
3
vacon • 14 CANopen protocol description
When an error occurs, the EMCY message is transmitted with the current value of the error register and the error code is inserted into the pre-defined error field list. The newest error code is always the first sub-index on the error field list. When all active errors are cleared, an empty EMCY object is transmitted.
If a drive-internal fault occurs, the MSEF field contains the drive fault code. See the application and user manual for possible fault codes. The ER field holds a bit coded value of the error type. See object 0x1001 for more details.

3.4 SDO protocol

The Option board contains one SDO server. The SDO protocol provides a direct access to the object entries of the object dictionary of the CANopen device. Each message is acknowledged by the server. The protocol is mostly used to set and read parameters from the object dictionary at the pre-operational state. Some objects have limitations for SDO usage at the operational state.
Up to four bytes can be transferred by using the expedited transfer, where the data fits into one CAN message. For bigger than 4-byte object sizes, segmented transfer must be used. Optionally, block transfer is also possible with bigger data types. Block transfer is most efficient with big data sizes.

3.5 PDO protocol

Process data objects PDOs are used to transmit real-time data with no protocol overhead. Each PDO has its mapping and communication parameter record.
There are two different types of PDOs. Transmit PDOs for producing data into network and Receive PDOs for consuming data from network. OPTE6 board supports 5 receive and 5 transmit PDOs.
Each of rxPDO and txPDO mapping parameter record contains four (4) process data items. For example, 0x01600 Receive PDO Mapping Parameter 1 contains following process data items:

received PDO value.
Synchronous means that the PDO is transmitted after the SYNC. The CANopen device starts sampling the data with the reception of the SYNC. If the transmission mode of the PDO is acyclic, the CANopen device gives an internal event, the sampling starts with the next SYNC and the PDO is transmitted afterwards. If the transmission mode is cyclic, the sampling starts with the reception of every SYNC, every second SYNC, every third SYNC etc. depending on the given value, and the PDO is transmitted afterwards.
RTR-only means that the PDO is requested via RTR. If the transmission mode of the PDO is synchronous, the CANopen device starts sampling with the reception of every SYNC and will buffer the PDO. If the mode is event-driven, the CANopen device starts the sampling with the reception of the RTR and transmits the PDO immediately.
Event-driven means that the PDO can be transmitted at any time based on the occurrence of the internal event of the CANopen device. An event that triggers the OPTE6 transmission occurs when the data mapped into the PDO is changed. Also, an event timer can be used to create transmit events.
Inhibit time
For transmit PDOs, the inhibit time defines the minimum transmission interval, when 0xFE or 0xFF transmission types are selected. For receive PDOs, the inhibit time is disabled. The inhibit time is 16bit unsigned value that is given as multiple of 100μs. Zero value means that the inhibit time is disabled.
3
vacon • 20 CANopen protocol description
Event timer
For a transmit PDO event, the timer defines the maximum interval between the transmissions, if the transmission type is set to 0xFE or 0xFF.
For a receive PDO event, the timer activates the deadline monitoring. The deadline monitoring is activated at the first received PDO. If the time between the after the last PDO received is longer than defined in the event timer, a fault will occur.
Event timer is 16bit unsigned value that is given as multiple of 1ms. Zero value means that the event timer is disabled.
NOTE: It is recommended to define non-zero Event timer value when using Event-driven transmission type. By default Event timer value is zero, which together with Event-driven transmission type means that OPTE6 CANopen transmits TPDO only when its data content changes. In certain situations TPDO data content rarely or never changes. For example, when running zero speed, TPDO1 data content (status word and actual speed) does not change after zero speed has been reached.
Sync start value
Sync start value gives the possibility to compensate network peak traffic in case of sync transmission mode. If the sync start value is zero, the normal sync behaviour for the PDO is used. If the sync start value is greater than zero, the PDO waits for the SYNC message that contains the counter value. When the counter value of a SYNC message equals the SYNC start value, the first SYNC message is regarded as received. The sync start value must not be changed while the PDO exists. See the SYNC message format in Table 30.

3.5.4 PDO parameter mapping record

Each PDO consists of a maximum of 8 bytes of mapped data. To data map the PDO, use a corresponding mapping record that consists of index, sub-index and the length of the mapped object.

To data map the PDOs, first disable the related PDO COB ID in the pre-operational state. In the mapping structure, write the sub-index 0 to zero (number of mapped objects). Then write the mapping structures on the mapping parameter record, starting from the sub-index 1. When you have written all the necessary structures, write the sub-index 0 to correspond to the mapped objects.
Example on how to write a dummy object to RPDO1 4th entry (when using Bypass mode) is explained below:

3.6 SYNC protocol

Sync protocol is used by PDOs when the transmission is synchronous. The sync object that is defined by COB ID in the object 0x1005 triggers the transmission of the txPDOs, or activates the previously received data of the rxPDO. At the default sync message the CAN-ID is 0x80. The sync message is a zero-length message but optionally it can consist of an 8bit counter.
Table 30: SYNC message
CAN ID LENGTH
0x80 0x0
Table 31: SYNC message with counter
CAN ID LENGTH DATA0
0x80 0x1 Counter

3.6.1 SYNC with counter

When a counter is used in a sync message, the PDOs that have a defined sync start value compare the value against the sync message counter. The sync producer counter will overflow after it reaches the value defined in its ‘synchronous counter overflow value’ at the object 0x1019. Also, the sync consumer has the object 0x1019 even when the value itself is ignored. When the value of the sync consumer is greater than zero, the sync counter handling and expecting of the sync messages with counter are activated.
When the sync start value and the sync counter value match, the first sync message is regarded as received.
The following figure shows an example of SYNC messaging, when the slave is configured with:
• 0x1019 - Synchronous counter 128
• 0x1800,2 - Transmission type = 2 (Cyclic, No. of SYNCs = 2)
• 0x1800,6 - Sync start value = 4

3.8 Saving and restoring the object dictionary

CANopen defines a way of restoring the values in an object dictionary to the defaults and saving the values if the modified values must be valid after the power cycle. The manufacturer-specific bypass configuration can be restored to the object dictionary.

3.8.1 0X1010 Store parameter field

To save the object dictionary, use the object 0x1010 ‘Store Parameter Field’.
The option board only saves the parameters in the object dictionary with a command. Autonomous saving is not supported. To save the parameters in the object dictionary, write the value 0x65766173 (ASCII “save”) into the sub-index by using the SDO protocol.

4.3 CAN cable

The recommended cables for installations are 4 wires twisted and a shielded cable with an impedance of 120 Ohm. The network topology is a 2-wire bus line that is terminated at both ends by resistors representing the characteristic impedance of the bus line. The typical CAN cable impedance is 120 Ohm, and so for the termination resistors of ~120 Ohm must be used. For long networks a higher resistor value must be used (150-300 Ohm).
