Overview
The JPC-01 network communication adapter module is designed to be used with
ABB drives. It provides communication capabilities between the drives and a
PC. The recommended PC adapter for this module is the MOXA UPort 1150i USB to
1 port RS-232/422/485 adapter with isolation.
Installation
- Insert the JPC-01 module into the panel port of the JCU control unit.
- Fasten the screw to secure the module.
RS-485 Cabling
The RS-485 cabling should be done in the bottom direction, parallel with the
I/O cabling. Refer to the appropriate ACSM1 hardware manual for detailed
instructions. The connection terminals for RS-485 are DATA-, DATA+, BGND, and
SH.
Quick Start-up with DriveStudio v1.6
- Ensure that all JCUs are powered and connected to the network.
- Set parameter 55.01 MDB STATION ID to a value between 1 and 31.
- Set parameter 55.02 MDB BAUD RATE to 57600 bit/s.
- Repeat the above steps for each drive, connecting them to the PC tool network one by one.
- After configuring the group 55 parameters for each drive, select OPC Server Settings from the Edit menu.
- Launch the ABBCOMSAP server configuration window from the taskbar.
Product Usage FAQs
Q: Who should perform electrical installation and maintenance work on the
drive?
A: All electrical installation and maintenance work on the drive should be
carried out by qualified electricians only.
About this manual
This manual introduces the installation and start-up of the JPC-01 network
communication adapter module. This manual is intended for the people who are
responsible for installing, commissioning and using a JPC-01 module with an
ABB drive. The reader is expected to have a basic knowledge of electrical
fundamentals, electrical wiring practices, the drive, and the use of the drive
control panel.
Safety instructions
WARNING!
All electrical installation and maintenance work on the drive should be
carried out by qualified electricians only.
- The drive and adjoining equipment must be properly earthed.
- Do not attempt any work on a powered drive. After switching off the supply voltage, always allow the intermediate circuit capacitors to discharge for 5 minutes before working on the drive, the motor or the motor cable. It is good practice to check (with a voltage-indicating instrument) that the drive is discharged before beginning work.
- These warnings are intended for all who work on the drive. Ignoring the instructions can cause physical injury or death, or damage the equipment.
- For complete safety instructions see the drive manuals.
Overview
- The JPC-01 module is an RS232-to-RS485 converter with galvanic isolation. It enables the use of a PC in a network configuration (RS485) to communicate with ACSM1 drives.
- The RS-232 side of the JPC-01 module acts as an interface towards the JCU control unit via the RJ45 panel connector. The RS-232 side also supplies power to the JPC-01 module.
- The RS-485 side of the JPC-01 module acts as an interface towards the PC tool network. It consists of a 4-pin removable screw-type connector and a termination switch for active termination of the RS485 bus. Termination is required only at the bus ends.
The JPC-01 supports:
- daisy-chained connection of the network cable,
- transmission speeds from 9.6 kbit/s in multiples up to 57.6 kbit/s,
- a maximum network length of 100 m, and a maximum node-to-node length of 30 m,
- a maximum of 31 drives in one network.
The recommended PC adapter is MOXA UPort 1150i USB to 1 port RS-232/422/485 adapter with isolation.
Layout
Installation
- Insert the JPC-01 module into the panel port of the JCU control unit.
- Fasten the screw.
RS-485 cabling is done in the bottom direction (parallel with the I/O cabling). For details, see the appropriate ACSM1 hardware manual. The connection terminals are DATA-, DATA+, BGND, and SH.
Quick start-up with DriveStudio v1.6
In DriveStudio v1.6, parameter group 55 COMMUNICATION TOOL is used for configuring the network. DriveStudio can be used for setting the parameters of one drive at a time and for monitoring the signals of several drives simultaneously.
With parameter 55.01 MDB STATION ID, the node number is set in the range of 1…247. With parameter 55.02 MDB BAUD RATE, the communication speed is defined. With the default setting, (0) Auto, the initial speed at power-up or after communication loss is 9600 bit/s. Note: Parameter 55.02 must be set to (0) Auto when using a control panel.
-
Ensure that your PC is connected to one of the drives at a time when configuring the RS-485 network. There are three ways to make the connection:
- Point-to-point connection from the PC directly to one of the JCUs
- Each JPC-01 is connected to its JCU but only one JCU-powered (network connection)
- Only one JPC-01 in the RS-485 chain is connected to a JCU (remaining JPC-01s detached from the JCU).
-
Set parameter 55.01 MDB STATION ID to a value between 1 and 31.
-
Set parameter 55.02 MDB BAUD RATE to the value of 57600 bit/s.
-
Repeat the procedure (steps 1…3) for the remaining drives; connect the drives to the PC tool network one by one.
Note: The new settings for parameters 55.01 and 55.02 become valid when the communication is interrupted either by restarting DriveStudio, removing the communication cable or restarting the JCU. -
After having configured group 55 for each drive, select OPC Server Settings from the Edit menu.
-
Launch the ABBCOMSAP server configuration window from the taskbar.
- COM Port shows all currently available COM ports.
- Default (247) defines the node number that DriveStudio uses when it communicates with the drives. With the box ticked, the node number used is 247 which represents a broadcast message to each drive (no response). With the box unticked, the node number range during the scan cycle is defined by the Start node and End node fields. By limiting the range the scan takes less time to finish.
- Default Speeds defines the baud rate used during the node scan cycle and normal communication. With the box ticked, the node scan is performed at 9600 bit/s; the speed is then increased to the maximum. With the box unticked, the speeds are defined by the Scan Speed and Comm Speed fields respectively.
- Leave the Default (247) and Default Speeds boxes ticked (default) during the point-to-point connection (steps 1…3).
-
Check the COM port used from DriveStudio.
-
Untick the boxes Default (247) and Default Speeds in the COM port used.
-
Change the setting of End node according to the maximum number of nodes.
-
Change the setting of Scan Speed to 57600 bit/s.
-
Leave the setting of Comm Speed on 57600 bit/s.
-
Click OK.
-
Connect all drives to the RS-485 network.
-
Scan the network by selecting View – Refresh or restarting DriveStudio.
-
DriveStudio will show all drives connected to the network.
