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 ,
and settings of setup 4 are used.
Parameter 002 (004) is not reset to
the original value when
communication is resumed.
VLT 5000 parameters are shown in parenthesis, where applicable.
