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.

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

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.

voltage is present.

Always

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.

vacon • 6 Safety

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 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 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.

1.3 Grounding and earth fault protection

CAUTION!

The AC drive must always be earthed with an grounding conductor connected to the grounding 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 mm

Al, through its total run.

b) Where the protective conductor has a cross-sectional area of less than 10 mm

Al, a second protective conductor of at least the same cross-sectional area must be

mm provided up to a point where the protective conductor has a cross-sectional area not less than 10 mm

Cu or 16 mm2 Al.

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

conductor.

Cu or 1 6 mm2

Cu or 16

The cross-sectional area of every protective grounding 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 can cause damage to the product.

4.5 Bus terminal and bias resistors

If VACON® AC drive is the last device of RS-485 line, the bus termination must be set. Use jumper X13 (ON position) or external termination resistors.

Bus biasing is required to ensure faultless communication between devices at RS-485 bus. Bus biasing makes sure that the bus state is at proper potential when no device is transmitting. Without biasing, faulty messages can be detected when the bus is in idle state. RS-485 bus state should be neither +0.200...+7 V or -0.200...-7 V. Illegal bus state is <200 mV...-200 mV.

The resistance of internal termination and biasing are 120 Ω and 560 Ω.

Cabling instructions vacon • 15

5. CABLING INSTRUCTIONS

5.1 Selecting cable

In EIA-485 systems, use only shielded cables with twisted-pair signal wires. With EIA-485 protocols, use for example:

• Lapp Kabel UNITRONICR BUS LD FD P A, part number 2170813 or 2170814

5.2 Setting the termination resistance

Install termination resistors at or near both ends of the EIA-485 segment. The typically termination resistor for EIA-485 is 120 Ω.

A. The termination is activated D. The bus termination B. The termination is deactivated E. The fieldbus cable C. The termination is activated with a jumper

Figure 7. Setting the termination resistance

5.3 Shield grounding options

The equipotential bonding system in an installation refers to metalwork that is used to bring earth potential everywhere in the installation to a common level, the system earth. The purpose is that the earth potential for all devices and equipment would be same, avoiding undesirable current flow through paths not normally designed to carry current, and to allow efficient shielding of cables.

5.3.1 Shield grounding when equipotential bonding is good

When the equipotential bonding is good, the fieldbus cable shield can be grounded at each AC drive. The grounding can be done by connecting the shield to the drive frame directly, or it can be done through the fieldbus connector and the grounding tab in the option board.

Figure 8. Jumper X14 setting (all points in system)

If the fieldbus cable is subjected to tensile load, it is recommended to do this grounding via the fieldbus board connector and grounding tab. The strain relief of the cable is then done without exposing the cable shield, which reduces the risk of mechanical wear on the cable.

Local contacts: https://www.danfoss.com/en/contact-us/contacts-list/

vacon • 16 Cabling instructions

Figure 9. Grounding by clambing the cable to the AC drive frame

5.3.2 Shield grounding when equipotential bonding is poor

In a situation where the equipotential bonding is poor, the fieldbus cable should be grounded directly only at one point in the system. This can be a VACON the system. The fieldbus cable should not be directly grounded elsewhere in the system, because difference in electrical potential can cause equalization currents to appear in the shield, causing unnecessary disturbances.

Figure 10. Jumper X14 setting (cable grounding to drive)

Figure 11. Jumper X14 setting (cable shield to RC filter)

In VACON filter, which helps filter out disturbances in the shield without directly connecting it to the earth. In this case, the shield is connected to the option board connector and through an RC filter to the grounding tab in the option board. The strain relief is done without exposing the cable shield.

AC drives, the fieldbus cable can in these cases be connected to ground through an RC

AC drive but can also be some other point in

Protocol communication timeout

NX mode enables OPTC2/OPTC8 RS485 emulation. See Chapter "OPTC2/OPTC8 RS485 compatibility mode".

Communication timeout

The OPTE2/E8 RS485 option board reports communication timeout fault to the AC drive if the option board cannot receive Modbus RTU or Metasys N2 request during a communication timeout time. For more information on the fault, see Chapter 14.3 "Fieldbus timeout fault (F53)".

Only Modbus RTU or Metasys N2 requests that are pointed to the option board are taken into account in the communication timeout calculation. Requests that are pointed to other devices do not affect the timeout calculation.

Timeout monitoring starts after one valid request is received from the master.

The OPTE2/E8 RS485 does not create communication timeout fault to the drive when the timeout value is set to zero. This is useful for example when Modbus RTU or N2 is used only for monitoring the AC drive.

OPTC2/OPTC8 RS485 compatibility mode

OPTE2/OPTE8 firmware V003 and newer support the NX mode which enables emulation of the old OPTC2/OPTC8 RS485 option board.

• N2 Binary input (BI) mapping is different. See Chapter 9.3.2 "Binary Input (BI)".

• N2 Binary output (BO) mapping is different. See Chapter 9.3.4 "Binary Output (BO)".

8. MODBUS RTU

8.1 Overview

The MODBUS protocol is an industrial communications and distributed control system to integrate PLCs, computers, terminals, and other monitoring, sensing, and control devices. MODBUS is a Master-Slave communications protocol. The Master controls all serial activity by selectively polling one or more slave devices. The protocol provides for one master device and up to 247 slave devices on a common line. Each device is assigned an address to distinguish it from all other connected devices.

The MODBUS protocol uses the master-slave technique, in which only one device (the master) can initiate a transaction. The other devices (the slaves) respond by supplying the request data to the master, or by taking the action requested in the query. The master can address individual slaves or initiate a broadcast message to all slaves. Slaves return a message ('response') to queries that are addressed to them individually. Responses are not returned to broadcast queries from the master.

8.2 Modbus RTU communications

Features of the Modbus-VACON® interface:

• Acts as a Modbus slave

• Direct control of VACON

• Full access to all VACON

• Monitor the status of the VACON code)

8.2.1 Data addresses in Modbus message

All data addresses in Modbus messages are referenced to zero. The first occurrence of a data item is addressed as item number zero. For example:

• Holding register 40001 is addressed as register 0000 in the data address field of the message. The function code field already specifies a 'holding register' operation. Therefore the '4XXXX' reference is implicit.

• Holding register 40108 is addressed as register 006B hex (107 decimal).

8.2.2 Modbus memory map

The VACON Modbus. The parameter addresses are determined in the application. Every parameter and actual value has been given an ID number in the application. The ID numbering of the parameters as well as the parameter ranges and steps can be found in the application manual in question. The parameter value is given without decimals. If several parameters/actual values are read with one message, the addresses of the parameters/actual values must be consecutive.

variables and fault codes as well as the parameters can be read and written from

8.3.1.1 VACON® application IDs

Application IDs are parameters that depend on the drive's application. These parameters can be read and written by pointing the corresponding memory range directly or by using the so-called ID map (more information below). It is easiest to use a straight address if you want to read a single parameter value or parameters with consecutive ID numbers. It is possible to read 12 consecutive ID addresses.

Read register/registers can fail with Modbus error "ILLEGAL DATA ADDRESS" in the following cases:

• Reading of a single application ID fails if the ID does not exist.

•In case of VACON reading of one ID fails.

- In "NX mode" OPTE2/E8 tries to read all registers. The read request succeeds if reading of one application ID succeeds. The failed application IDs are set to zero in the Modbus

response data. If OPTE2/8 is used in VACON® NX AC drives, this mode is enabled automatically.

• In case of 32-bit address space the read operation fails if only half of the 32-bit value is read. The read request must read complete 32-bit values.

8.3.1.2

Drive System time

VACON® NX and VACON® 100 product families support reading and setting of drive system time via fieldbus. It is also possible to synchronize time by using SNTP protocol. For details of the functionality, see Ethernet fieldbus manuals.

With OPTE2/E8 Modbus RTU it is possible to read and write drive system time via ID 2551. The time is presented as unsigned 32-bit unix time. For example, unix time 1536315873 (0x5B9251E1) stands for 07-Sep-2018 10:24:33.

Example: Read or write drive system time by using 32-bit application parameter access. Modbus address 25102 (low data) becomes from calculation "32-bit area start address" + (application ID * 2) = 20000 + (2551 * 2).

The use of process data depends on the application. In a typical situation, the device is started and stopped with the Control Word (CW) written by the Master and the Rotating speed is set with Reference (REF). With PD1…PD8 the device can be given other reference values (e.g. Torque reference).

With the Status Word (SW) read by the Master, the status of the device can be seen. Actual Value (ACT) and PD1…PD8 show the other actual values.

ID map

Using the ID map, you can read consecutive memory blocks that contain parameters whose ID's are not in a consecutive order. The address range 10501 - 10530 is called 'IDMap', and it includes an address map in which you can write your parameter IDs in any order. The address range 10601 to 10630 is called 'IDMap Read/Write,' and it includes values for parameters written in the IDMap. As soon as one ID number has been written in the map cell 10501, the corresponding parameter value can be read and written in the address 10601, and so on. The address range 10701 - 10730 contains the ID Map for 32bit values.

Metasys N2 vacon • 63

9. METASYS N2

9.1 Overview

The N2 communications protocol is used by Johnson Controls and others to connect terminal unit controllers to supervisory controllers. It is open to any manufacturer and based upon simple ASCII protocol widely used in the process control industry.

The physical characteristics of the N2 bus are two wires RS-485 with a maximum of 100 devices over a 4000 foot distance running at 9600 bps by default. Logically, the N2 is a master-slave protocol, the supervisory controller normally being the master.

9.2 Metasys N2 communication

Features of the N2 interface:

• Direct control of drive (e.g. Run, Stop, Direction, Speed reference, Fault reset)

• Full access to necessary parameters

• Monitor drive status (e.g. Output frequency, Output current, Fault code)

• In standalone operation, or should the polling stop, the overridden values are released after a specified period.

9.2.1 Analogue Input (AI)

All Analogue Input (AI) points have the following features:

• Support Change of State (COS) reporting based on high and low warning limits.

• Support Change of State (COS) reporting based on high and low alarm limits.

• Support Change of State (COS) reporting based on override status.

• Always considered reliable and never out of range.

• Writing of alarm and warning limit values beyond the range that can be held by the drive's internal variable will result in having that limit replaced by the "Invalid Float" value even though the message is acknowledged. The net result will be the inactivation of the alarm or warning (the same as if the original out of range value was used).

• Overriding is supported from the standpoint that the "Override Active" bit will be set and the value reported to the N2 network will be the overridden value. However, the value in the drive remains unchanged. Therefore, the N2 system should be set up to disallow overriding AI points or have an alarm condition activated when an AI point is overridden.

• Overriding an AI point with a value beyond the limit allowed by the drive's internal variable will result in an "Invalid Data" error response and the override status and value will remain unchanged.

9.2.2 Binary Input (BI)

All Binary Input (BI) points have the following features:

• Support Change of State (COS) reporting based on current state.

• Support Change of State (COS) reporting based on alarm condition.

• Support Change of State (COS) reporting based on override status.

• Always considered reliable.

Overriding is supported from the standpoint that the "Override Active" bit will be set and the value reported to the N2 network will be the overridden value. However, the value in the drive remains unchanged. Therefore, the N2 system should be set up to disallow overriding BI points or have an alarm condition activated when a BI point is overridden.

vacon • 64 Metasys N2

9.2.3 Analogue Output (AO)

All Analogue Output (AO) points have the following features:

• Support Change of State (COS) reporting based on override status.

• Always considered reliable.

• Overriding of the AO points is the method used to change a value. Overriding an AO point with a value beyond the limit allowed by the drive's internal variable will result in an "Invalid Data" error response and the override status and value will remain unchanged. If the overridden value is beyond the drive's parameter limit but within the range that will fit in the variable, an acknowledge response is given and the value will be internally clamped to its limit.

• An AO point override copies the override value to the corresponding drive parameter. This is the same as changing the value on the keypad. The value is non-volatile and will remain in effect when the drive is turned off and back on. It also remains at this value when the N2 network "releases" the point. The N2 system always reads the current parameter value.

NOTE! On some N2 systems, the system will not poll the AO point when it is being overridden. In this case, the N2 system will not notice a change in value if the change is made with the keypad. To avoid this, set the point up as a "local control" type and release it once it has been overridden. In this way, the N2 system will monitor the value when not being overridden.

9.2.4 Binary Output (BO)

All Binary Output (BO) points have the following features:

• Support Change of State (COS) reporting based on override status.

• Always considered reliable.

• Overriding BO points control the drive. These points are input commands to the drive. When released, the drive's internal value remains at its last overridden value.

9.2.5 Internal Integer (ADI)

All Internal Integer (ADI) points have the following features:

• Do not support Change of State (COS) reporting.

• Can be overridden and the "Override Active" bit will be set. However, the Internal value is unchanged (Read only).

vacon • 70 Appendix A - Fieldbus parametrization

10. APPENDIX A - FIELDBUS PARAMETRIZATION

The following chapter describes briefly how to parametrize the AC drive in order for the motor to be controllable via fieldbus. These instructions are written for some basic applications. For more information, see the application specific manual.

In order for the AC drive to accept commands from the fieldbus network, the control place of the AC drive has to be set to fieldbus. The default value of the parameter "Control Place" is usually I/O. Note that if the control unit firmware is updated, the default settings are restored. In addition, some applications may have the remote speed reference selection set by default to other than fieldbus. In these cases, the speed reference selection must be set to fieldbus, in order for the speed reference to be controlled via fieldbus.

NOTE! The motor control mode should be selected to support the used process and profile.

10.1 Fieldbus control and basic reference selection

The following tables list some of the parameters related to fieldbus control in case of standard applications for the VACON the application specific manuals for more detailed information and latest updates.

The parameters can be read and written by using the drive panel, PC tools or fieldbus protocol. The following table contains links to chapters where the ID value reading is described.

10.2 Controlling fieldbus parameter

VACON® 100 family AC drives have parameter called “P5.13.1 Controlling Fieldbus”. It is used to select the instance from which the process data is sent to the drive application. By default, the setting is in "Automatic" and the functionality (when receiving process data from multiple sources) is application dependent.

The parameters only show options that are possible with the used software and hardware configuration. For example, slot E is shown only if the option board slot E contains a fieldbus option board. The use of VACON

100 family built-in PROFINET IO and EtherNet/IP requires a license.

Local contacts: https://www.danfoss.com/en/contact-us/contacts-list/

vacon • 72 Appendix A - Fieldbus parametrization

For example, if the option board has been installed to slot E and it is used with PROFINET to control the drive, the user can select "Slot E" as value for this parameter. Now only the process data from the option board in slot E is forwarded to the application. All other fieldbuses still receive process data out. With this setting it is possible to prevent that the monitoring fieldbuses accidentally write process data in.

10.3 Torque control parametrization

Some extra parametrization must be made in order to control the frequency control with torque control. The following instructions are for the VACON

application. For more information, see the application specific manual.

• Motor control mode (ID 600) must be configured to “Torque control” (2).

To configure the AC drive to use correct torque reference, select the parameter "Torque Reference Selection" to ProcessDataIn1 (9). This can be done with:

• PC tool or panel (VACON

100 family: P3.3.2.1, VACON® NXP/NXS: P2.10.4) / ID 641

• Vendor Parameter Object

100 family and VACON® NXP/NXS

10.4 Response to fieldbus fault

In case of a fieldbus fault (for example, loss of connection), a fieldbus fault is triggered. This fault can be parametrized in application to result in a desired response. Always check the application specific manual for details as responses vary between used applications. For common fault responses used commonly in standard applications, see the table below.

11.6 VACON® speed reference and actual speed - FBSpeedReference and FBActualSpeed

The FBSpeedReference value is signed in the range of -10000...10000d (d8f0...2710h). The given reference is scaled in percentage between the minimum and maximum frequency parameters by application. The value 0 corresponds to minimum frequency and the value 10000d corresponds to maximum frequency. The scale of the value is 0.01%. Negative value indicates direction. If the direction bit in control word is set (means direction should be counterclockwise) and the reference is negative, motor runs clockwise despite the direction bit.

The FBActualSpeed value is signed in the range -10000...10000d (d8f0...2710h). Actual speed is scaled in percentage between the minimum and maximum frequency parameters by application. The value 0 corresponds to minimum frequency and the value 10000d corresponds to maximum frequency. The scale of the value is 0.01%.

Some VACON

-10000...10000d (d8f0...2710h). When using control modes that are fieldbus protocol specific, for example PROFIdrive, exceeding the speed value range is not possible.

NOTE! Some VACON direction must be controlled with control word's direction bit. Some VACON negative reference but the actual speed is always positive. In this case the direction status must be read from status word's direction bit.

11.7 Process data

The process data variables are vendor specific variables that can be communicated to and from the AC drive. Eight process data items can be communicated between PLC and the drive. Some drives and firmware versions can support up to sixteen process data items. If the drive does not support 9–16 process data items, then the incoming 9–16 process data items are ignored and outgoing 9–16 process data items are set to zero. For more information, see chapter “12. Appendix C - Fieldbus option board communication” and chapter “13. Appendix D - Parameters for application developers”.

Values sent from the drive to the PLC are called ProcessDataOut variables, whereas the values sent from the PLC to the drive are called ProcessDataIn variables. The contents of the ProcessDataOut variables can be parametrized in the AC drive using a feature known as Fieldbus process data mapping. For more information, see the following chapter.

11.8 Fieldbus process data mapping and scaling

This chapter describes how standard applications map process data items by default. For more information, especially when not using a standard application, see the application manual for the AC drive in use.

Appendix E - Fault tracing vacon • 93

14. APPENDIX E - FAULT TRACING

When the option board or the AC drive control diagnostics detect an unusual operating condition, the drive opens a notification, for example, on the keypad. The keypad shows the ordinal number of the fault, the fault code and a short fault description. You can reset the fault with the Reset button on the control keypad, via the I/O terminal or via the used fieldbus protocol. The faults are stored in the Fault history menu, which can be browsed. The fault table presents only the fault conditions related to the fieldbus in use.

NOTE! When you contact a distributor or a factory because of a fault condition, always write down all texts and codes on the keypad display. Then send the problem description together with the Drive Info File to the local distributor. If possible, also send a fieldbus communication log from the situation if applicable.

Service Info can be read from the drive with PC tool.

14.1 Diagnostic information

OPTE2/8 RS485 offers the following diagnostic information for problem solving:

• Monitor values. See Chapter 7.1.1 Option board monitor menu.

• Option board LEDs. See Chapter 4.3 LED indications.

• Fieldbus fault diagnostic. See Chapter 14.3.2 Fieldbus timeout fault (F53) diagnostic info.

14.2 Typical fault conditions

14.2.1 PLC master cannot get response from OPTE2/E8 RS485

Modbus RTU master or N2 master cannot get response from OPTE2/E8 RS485.

1. Check OPTE2/E8 RS485 board's LED status that is described in Chapter 4.3 LED indications.

• If all three LED’s are green, then OPTE2/E8 receives requests from the PLC master with a correct slave address.  Check PLC master status again.

• If the PS led is flashing yellow and the BS led is flashing red, then OPTE2/E8 RS485 has activated Fieldbus timeout fault (F53). This means that OPTE2/E8 received requests from the PLC master with a correct slave address but that connection to PLC master was lost.

• In other cases OPTE2/E8 RS485 has not communicated with the PLC master.

2. Check "Communication Status" monitor value that is described in Chapter 7.1.1 Option board monitor menu.

• If the number of messages without errors increases, then OPTE2/E8 RS485 is successfully

receiving frames from the PLC master but probably with a different slave address.  See step 3. Check that the slave address is correct

• If the number of messages with errors increases, then OPTE2/E8 RS485 is receiving

corrupted frames from the bus.  See step 4. Check baud rate and parity settings.  Check cabling and connectivity described in steps 5–11.

• If "Communication Status" monitor value counters are not increasing, then OPTE2/E8 RS485

is not receiving any data from the bus.  Check cabling and connectivity described in steps 5–11.

3. Check that the slave address is correct.

• Check that the PLC master sends the frames with the same slave address as configured

with Slave Address panel parameter which is described in Chapter 7.1.2 Option board parameter menu.

• Check that the RS485 bus does not have two slave devices with the same slave address.

4. Check baud rate and parity settings.

• Check that OPTE2/E8 RS485 uses the same baud rate and parity as used by the PLC master.

Baud rate and parity parameters are described in Chapter 7.1.2 Option board parameter menu.

5. Check that the RS485 bus is terminated properly from both ends.

• RS485 communication might work without termination with slow baud rates in a short

distance. Despite of this bus termination is always required.

• If OPTE2/E8 is the last device of a RS485 bus, termination must be set in OPTE2/E8. For

instructions, Chapter 4.4 Jumpers.

6. Check that the RS485 bus is biased properly. Biasing ensures that the bus state is at a proper potential when no device is transmitting.

• Typically bias voltage is generated from one device in the RS485 bus.

• Bias voltage can be generated from OPTE2/E8 according instructions in Chapter 4.5 Bus

terminal and bias resistors.

7. Check that the RS485 cable is connected correctly to the OPTE2/E8 option board's connector. For pin layout, see Chapter 4. Layout and connections.

8. Check that the RS485 cable is not short-circuited.

Local contacts: https://www.danfoss.com/en/contact-us/contacts-list/

Appendix E - Fault tracing vacon • 95

9. Check that the supply or motor cable is not located too close to the RS485 cable.

• The supply or motor cable can cross the RS485 cable in a 90-degree angle. However, it is

problematic if the supply or motor cable is placed into the same cable duct with the RS485 cable.

• If it is possible that the supply or motor cable causes communication problems, the impact

of the supply or motor cable can be tested with the following procedure:

1. Disconnect the main supply from the automation devices.

2. Power on the control unit of VACON

control unit, see AC drive manual.

3. Test the communication with the PLC master.

10. Check grounding of the cable shield and the related OPTE2/E8 option board jumper settings.

• The OPTE2/E8 option board supports different shield grounding options. For for information,

see Chapter 5.3 Shield grounding options.

11. Check that the RS485 cable is not too long.

• If it is possible that RS485 cable it too long, then try to use lower baud rate in

communication.

14.2.2 Data corruption in communication

Communication works at some level but the PLC master or OPTE2/E8 option board reports data corruption on bus. The OPTE2/E8 option board's "Communication Status" monitor tells if the option board receives corrupted data from the bus. For information on monitor value, see Chapter 7.1.1 Option board monitor menu.

Check steps 5–11 in Chapter 14.2.1 PLC master cannot get response from OPTE2/E8 RS485.

14.2.3 AC drive does not start to run

The PLC master gives a run command to the AC drive via Modbus RTU or N2 but the motor is not started.

AC drive with +24 V. For instructions on powering the

1. Check that the AC drive is configured to fieldbus control. See Chapter 10. Appendix A - Fieldbus parametrization.

2. Check that fault is not active in the AC drive. For fault behavior in used AC drive, see AC drive specific manual.

3. Check that the AC drive is in "Ready" state.

•VACON

•For VACON

4. Check that OPTE2/E8 is in “Operational” state:

"Fieldbus protocol status" monitor value tells the state of the OPTE2/E8 option board. For more information, see Chapter 7.1.1 Option board monitor menu.

• If the status is "Initializing", then OPTE2/E8 is waiting for communication from the PLC

master. Follow instructions in Chapter 14.2.1 PLC master cannot get response from OPTE2/ E8 RS485.

• If the status is "Faulted", then communication has been active between the PLC master and

OPTE2/E8 but connection to PLC master was lost. Connection should be re-established again, and the possible Field bus timeout fault (F53) should be cleared in the AC drive. For fault behavior, see AC drive specific manual.

• If the status is "Operational", then OPTE2/E8 RS485 is receiving requests from the PLC

master with a correct slave address, but probably the format of the commands is incorrect.

NX and VACON® 100 family AC drives show this information in the keypad panel.

20 and VACON® 20 X/CP AC drives, see AC drive specific manual.

5. Check that OPTE2/E8 really receives run command from the PLC master. Control words and status words handled by OPTE2/E8 can be seen from the monitor values. See the following monitor values in Chapter 7.1.1 Option board monitor menu.

• Protocol/Fieldbus control word

• Protocol/Fieldbus status word

6. Check that the AC drive application understands the control word given by the PLC master.

• In most cases VACON

word format described in Chapter 11. Appendix B - VACON some applications support special command modes. For example, VACON

application (APFIFF08) supports PROFIdrive mode where the control word must be given in PROFIdrive format.  For control word format, see application manual.

7. Check special requirements of the AC drive application.

• Some applications have special requirements for motor controlling. For example, VACON

NXP SIAII application (APFIFF40) requires by default that digital inputs DIN4 (Run enable), DIN5 (Switch is closed) and DIN6 (Quick stop active) are connected before running the motor is possible.  For applications specific requirements, see application manual

14.2.5 AC drive reports Fieldbus timeout fault (F53)

See Chapter 14.3 Fieldbus timeout fault (F53).

14.2.6 Fieldbus timeout fault (F53) cannot be reset

See Chapter 14.3 Fieldbus timeout fault (F53).

14.3 Fieldbus timeout fault (F53)

VACON® fieldbuses create a fieldbus timeout fault (F53) when a fault occurs in the fieldbus protocol and the AC drive is set to fieldbus control.

NOTE! If the control place is set to e.g. I/O, no fieldbus fault is triggered even if a fault condition is detected. The fault response can also be modified in the AC drive application. For more information, see Chapter 10. Appendix A - Fieldbus parametrization.

NOTE! Some drive applications require that the fieldbus writes non-zero process data before fieldbus fault activation is possible.

14.3.1 OPTE2/E8 RS485 fault conditions

OPTE2/E8 creates a Fieldbus fault F53 in the conditions described in the following table.

NOTE! Connection to the PLC master must be re-established before resetting the F53 Fieldbus fault is possible.

parameter (Chapter 7.1.2 Option board parameter menu). Corrupted data frames are received during the timeout time.

• OPTE2/E8 cannot receive a valid request from the PLC master within time defined by the Communication timeout parameter (Chapter 7.1.2 Option board parameter menu).

• It is possible that OPTE2/E8 receives requests addressed to some other slave.

14.3.2 Fieldbus timeout fault (F53) diagnostic info

In VACON feature is available from VACON

100 family a detailed fault code for fieldbuses is "Source3" in the fault history. This
