Function:

The time out timer is triggered at the first

reception of a valid control word, i.e.,

bit 10 = ok.

The time out function can be activated in two

different ways:

1. The drive does not receive a

LonWorks command addressed to it

within the specified time.

2. Parameter 805 is set to “bit 10 = 0

time out” and a control word with “bit

10 = 0” is sent to the drive.

The VLT remains in the time out state until

one of the following four conditions is true:

1. A valid control word (Bit 10 = ok) is

received and the drive is reset

through the bus, the digital input

terminals or the local control panel.

(Reset is only necessary when the

time out function

Stop w/trip

is

selected.) Control via LonWorks is

resumed using the received control

word.

2. Local control via the local control

panel is enabled.

3. Parameter 928,

Access to process

control

, is set to

Disabled

.

Normal control via the digital input

terminals and the RS-485 interface is

now enabled.

★ Factory setting

4. Parameter 804,

Bus time out function

,

is set to

Off.

Control via LonWorks is resumed and

the most recent control word is used.

Description of Selections:

•

Freeze output frequency

. Maintain

present output frequency until

communication is resumed.

•

Stop with auto restart

. Stop and

automatically restart when

communication is resumed.

•

Output frequency = JOG freq

. Drive

will produce JOG frequency set in

parameter 209 (213),

Jog frequency

,

until communication is resumed.

•

Output frequency = Max. freq

. Drive

will produce maximum output

frequency (set in parameter 202,

Output frequency

) until

communication is resumed.

•

Stop with trip.

Drive stops and

requires a reset command before it

will restart.

•

Control without LonWorks

. Control via

LonWorks is disabled. Control is

possible via digital input terminals

and/or standard RS-485 interface

until LonWorks communication is

resumed.

•

Select setup 4

. Setup 4 is selected in

parameter 002 (004),

Active setup
