for the fieldbus installed in slot A will be visible in the display.

For guidelines in selection of [0] FC profile and [1] PROFIdrive

profile refer to the Serial communication via RS-485 Interface

section.

Function:

Select the action after receiving a valid control

word following a time-out. This parameter is

active only when 8-04 Control Timeout Function

is set to [7] Set-up 1, [8] Set-up 2, [9]Set-up 3 or

[10] Set-up 4.

Retains the set-up selected in 8-04 Control

Timeout Function and displays a warning, until

8-06 Reset Control Timeout toggles. Then the

frequency converter resumes its original set-up.

Resumes the set-up active before the time-out.

Function:

Word Timeout Function, following a control

word time-out.

Returns the frequency converter to the original

set-up following a control word time-out. The

frequency converter performs the reset and

then immediately reverts to the [0] Do not reset

setting

Function:

FC profile

PROFIdrive profile

ODVA

CANopen DSP 402

MCO

Function:

This parameter enables configuration of

bits 12–15 in the status word.

Function corresponds to the profile

default selected in 8-10 Control Profile.

Only set in case of an Alarm 68.

Set in case of a trip, except if Alarm 68

executes the trip.

Function:

The bit indicates the status of terminal 18.

"0" indicates that the terminal is low

"1" indicates that the terminal is high

The bit indicates the status of terminal 19.

"0" indicates that the terminal is low

"1" indicates that the terminal is high

The bit indicates the status of terminal 27.

"0" indicates that the terminal is low

"1" indicates that the terminal is high

The bit indicates the status of terminal 29.

"0" indicates that the terminal is low

"1" indicates that the terminal is high

The bit indicates the status of terminal 32.

"0" indicates that the terminal is low

"1" indicates that the terminal is high

The bit indicates the status of terminal 33.

"0" indicates that the terminal is low

"1" indicates that the terminal is high

The bit indicates the status of terminal 37.

"0" indicates T37 is low (safe stop)

"1" indicates T37 is high (normal)

The thermal warning turns on when the

temperature exceeds the limit in the

motor, the frequency converter, the brake

resistor, or the thermistor.

Output is Logic '1' when the brake IGBT is

short-circuited. Use this function to

protect the frequency converter if there is

a fault on the brake modules. Use the

output/relay to cut out the main voltage

from the frequency converter.
