VLT
®
5000 INTERBUS
Parameters
928 Process control
Selections:
Disabled
[0]
✭
Enabled
[1]
Function:
Process control (setting of control word and speed
reference) is possible via either INTERBUS or the
standard RS485 interface, but not both at the same
time. Local control is always possible via the local
control panel. Control via control card terminals is
possible with either bus depending on the setting of
parameters 502-508.
Description of selections:
-
Disabled
: Process control via INTERBUS is
disabled. Process control via standard RS485 is
possible.
-
Enabled
: Process control via INTERBUS is
enabled. Process control via standard RS485 is
blocked.
The motor may start without notice when
parameter 928 is changed and start commands are
present.

971 Store data values
(STORE DATA VALUE)
Selections:
✭
No action
(NO ACTION)
[0]
Store active setup (STORE ACTIVE SETUP) [1]
Store all setups (STORE ALL SETUPS) [2]
Store edit setup (STORE EDIT SETUP) [3]
Function:
Parameter values changed via INTERBUS are only
stored in RAM meaning that the changes are lost at
power down. This parameter is used to activate a
function that stores all parameter values in the
EEPROM thus retaining changed parameter values at
power down.
Description of selections:
No action:
The store function is inactive.
Store active setup:
All parameter values in the
active setup will be stored in the EEPROM. The
value returns to
No action
when all parameter
values have been stored.
Store all setups
: All parameter values will be stored
in the EEPROM. The value returns to
No action
when all parameter values have been stored.
Store edit setup
: All parameter values in the setup
you are editing will be stored in the EEPROM. The
value returns to
No action
when all parameter
values have been stored.
980-982 Defined parameters
(DEFINED PNU'S)
Selections:
Read only
Function:
These three parameters hold a list of all the
parameters that are defined in the VLT. Each of the
three parameters can be read as an array by means of
the PCP
read
service. It is also possible to read single
elements of the list by
PCP Communication, b
y using
the corresponding subindex. The subindexes start at
1 and follow the order of the parameter numbers.
