5.10 Displaying parameters with non-
default values only
By selecting 'Show non-default' in Pr mm.000 (Alternatively, enter 12000
in Pr mm.000), the only parameters that will be visible to the user will be
those containing a non-default value. This function does not require a
drive reset to become active. In order to deactivate this function, return
to Pr mm.000 and select 'No action' (alternatively enter a value of 0).
Please note that this function can be affected by the access level
enabled, refer to section 5.9 Parameter access level and security on
page 109 for further information regarding access level.
5.11 Displaying destination parameters only
By selecting 'Destinations' in Pr mm.000 (Alternatively enter 12001 in
Pr mm.000), the only parameters that will be visible to the user will be
destination parameters. This function does not require a drive reset to
become active. In order to deactivate this function, return to Pr mm.000
and select 'No action' (alternatively enter a value of 0).
Please note that this function can be affected by the access level
enabled, refer to section 5.9 Parameter access level and security on
page 109 for further information regarding access level.
5.12 Communications
The Powerdrive F300 drive offers a 2 wire 485 interface. This enables
the drive set-up, operation and monitoring to be carried out with a PC or
controller if required.
5.12.1

485 Serial communications

The EIA485 option provides two parallel RJ45 connectors allowing easy
daisy chaining. The drive only supports Modbus RTU protocol.
The serial communications port of the drive is a RJ45 socket, which is
isolated from the power stage and the other control terminals (see
section 4.11 Communications connections on page 97 for connection
and isolation details).
The communications port applies a 2 unit load to the communications
network.

USB/EIA232 to EIA485 Communications

An external USB/EIA232 hardware interface such as a PC cannot be
used directly with the 2-wire EIA485 interface of the drive. Therefore a
suitable converter is required.
Suitable USB to EIA485 and EIA232 to EIA485 isolated converters are
available from Control Techniques as follows:
• CT USB Comms cable (CT Part No. 4500-0096)
• CT EIA232 Comms cable (CT Part No. 4500-0087)
NOTE
When using the CT EIA232 Comms cable the available baud rate is
limited to 19.2 k baud.
When using one of the above converters or any other suitable converter
with the drive, it is recommended that no terminating resistors be
connected on the network. It may be necessary to 'link out' the
terminating resistor within the converter depending on which type is
used. The information on how to link out the terminating resistor will
normally be contained in the user information supplied with the
converter.

8 2 NP (0),
8 1 NP (1),
8 1 EP (2),
8 1 OP (3), The drive only supports the
8 2 NP M (4), Modbus RTU protocol and is
8 1 NP M (5), always a slave. This parameter
8 1 EP M (6), defines the supported data
8 1 OP M (7), formats used by the 485
7 2 NP (8), comms port (if installed) on the
7 1 NP (9), drive. This parameter can be
7 1 EP (10), changed via the drive keypad,
7 1 OP (11), via a option module or via the
7 2 NP M (12), comms interface itself.
7 1 NP M (13),
7 1 EP M (14),
7 1 OP M (15)
300 (0), This parameter can be
600 (1), changed via the drive keypad,
1200 (2), via a option module or via the
2400 (3), comms interface itself. If it is
4800 (4), changed via the comms
9600 (5), interface, the response to the
19200 (6), command uses the original
38400 (7), baud rate. The master should
57600(8), wait at least 20 ms before
76800(9), sending a new message using
115200 (10) the new baud rate.
This parameter defines the
serial address and an
1 to 247
addresses between 1 and 247
are permitted.
