Example of CANopen configuration
The following diagram shows an example of four ATV 31, connected to a master PLC Premium with a CANopen master PCMCIA card (TSX CPP 110).
Various accessories are available from the catalogue to realise connection of devices.
ATV 31 CANopen tap is a passive tap (reference: VW3 CAN TAP 2) It can be connected on a CANopen trunk cable, using the two 5-screw terminals embedded connectors. Two RJ45 connectors allow the connection of two Altivar 31 by ATV 31 CANopen drop cords. One RJ45 connector is designed to interface these two Altivar 31 with PowerSuite (Commissioning software tool for PC or Pocket PC).
If only one ATV 31 is connected on the tap it should be on the connector labelled "ATV1". If two ATV 31 are connected, PowerSuite can access the two drives in multidrop mode. The Modbus address of each drive must be different.
A remote terminal (VW3 A31101) can also be connected to the "PowerSuite" connector, but in this case, only one ATV 31 drive can be connected to the CANopen tap (on the plug labelled "ATV1").
ATV 31 CANopen drop cord is a cable equipped with 2 RJ45 connectors. Two lengths are available: 0.3 m (reference: VW3 CAN CA RR 03) and 1 m (reference: VW3 CAN CA RR1).
Only a 0.3 m drop cord can be used in a CANopen network at a speed of 1 Mbits/s.

Connecting the drive to the ATV 31 CANopen tap
Connect the cord with 2 RJ45 connectors (VW3 CAN CA RR 03 or VW3 CAN CA RR 1) to the RJ45 connector of the drive and to the “ATV1” or “ATV2” female RJ45 connector located on the ATV 31 CANopen tap (VW3 CAN TAP 2).
If only one Altivar 31 is connected to the ATV 31 CANopen tap the “ATV1” connector must be used.

Setup of the CANopen tap
Tools required:
• 2.5 mm flat screwdriver.
• PZ01 cross recess screwdriver.
Procedure: Note: the numbers shown below correspond to the numbers in the tap description.
• Unscrew screw 1 using a PZ01 screwdriver. Open cover.
• Fix the tap base to its support:
- either to an AM1-DP200 or AM1-DE 200 DIN rail
- or to a plate or panel using 2 M4 screws at least 20 mm long
• Prepare trunk cables 20 and 21, as shown on the following pages.
• Position grounding clamps 22 on the cables.
• Position ground connection 23.
• Connect the trunk cables to terminal blocks 7, as shown on the following pages. Use a 2.5 mm flat screwdriver. Thread torque on terminal block screw
• Screw down the grounding clamps and connections using screws 19 and a cross recess screwdriver (PZ01).
• Connect the green/yellow grounding wire to the connection lug 6.
• Immobilise the cables using nylon clamps.
• Position micro-switch to ON if line termination is required and to OFF if not.
• Break the tabs on the cover so that the cables can pass through.
y 0.25 N.m.
• Replace cover and fix it in place with screw 1 using a cross recess screwdriver (PZ01).

Configuration

Configuration of the CANopen communication functions of the Altivar 31 can be accessed from the Communication menu /98! .
The configuration can only be modified when the motor is stopped and the drive is locked. Any change will only be applied after a power cycle of the drive (power off then power on).
Parameter Possible values Terminal display Default value
CANopen Address
-@/#
CANopen Speed
>@/#
The -@/# parameter will thereafter be referred to as “Node-ID” in the present User’s Manual.
The default value (0) of this parameter disables the CANopen communications of the Altivar 31.
In order to enable CANopen on the Altivar 31, you must set a non-zero value for -@/#.
The value of the >@/# parameter must match the communication speed of all the other devices connected to the CANopen bus.
In addition, the maximum length of the bus depends on the communication speed. The following table specifies the maximum bus length when an Altivar 31 is placed on a CANopen bus, depending on the actual communication speed:
0 to 127 # to $%* 0
0,010 kbits/s
20 kbits/s
50 kbits/s 125 kbits/s 250 kbits/s 500 kbits/s
1,000 kbits/s
0$#.#
#%#.# #(#.# $%(.# %(#.# (##.#

125 kbits/s
Communication speed 10 kbits/s 20 kbits/s 50 kbits/s 125 kbits/s 250 kbits/s 500 kbits/s 1,000 kbits/s Maximum length of the bus 5,000 m 2,500 m 1,000 m 500 m 250 m 100 m 5 m
Some other documents specify greater lengths, they only apply to CANopen devices without galvanic insulation. Due to galvanic insulation of the CANopen interface of ATV 31, the lengths mentioned in the table above must be respected .
At the speed of 1,000 kbits/s, the lenght of the drops must be limited to 0.3 m.

Signalling

The two signalling LEDs located immediately on the right of the 4-digit 7-segment front display unit of the Altivar 31 are used to indicate the status of the CANopen communications.
