NOTE: Although the VSD will detect a failure in the brake<br />

electronics, the use of resistors with a thermal overload<br />

which will cut off the power at overload is strongly<br />

recommended.<br />

The brake chopper option is built-in by the manufacturer<br />

and must be specified when the VSD is ordered.<br />

13.4 I/O Board<br />

Order number<br />

01-3876-01 I/O option board 2.0<br />

The I/O option board 2.0 provides three extra relay<br />

outputs and three extra digital inputs. The I/O Board<br />

works in combination with the Pump/Fan Control, but<br />

can also be used as a separate option. This option is<br />

described in a separate manual.<br />

13.5 Output coils<br />

Output coils, which are supplied separately, are recommended<br />

for lengths of screened motor cable<br />

longer than 100 m. Because of the fast switching of<br />

the motor voltage and the capacitance of the motor<br />

cable both line to line and line to earth screen, large<br />

switching currents can be generated with long lengths<br />

of motor cable. Output coils prevent the VSD from tripping<br />

and should be installed as closely as possible to<br />

the VSD.<br />

13.6 Serial communication and<br />

fieldbus<br />

Order number<br />

01-3876-04 RS232/485<br />

01-3876-06 DeviceNet<br />

Description<br />

Description<br />

01-3876-09 Modbus/TCP, Ethernet<br />

For communication with the VSD there are several<br />

option boards for communication. There are different<br />

options for Fieldbus communication and one serial<br />

communication option with RS232 or RS485 interface<br />

which has galvanic isolation.<br />
