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 in fact 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 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 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.
