Programming; Quick Setup; Special Attention - Danfoss VLT 5000 Operating Instructions Manual

Quick Setup

For how to program the ordinary VLT parameters
refer to the VLT 5000 Series Instruction Manual.
Communication is established by setting the
following parameters:
Parameter 904:
Select the PPO type to be applied.
Parameter 918:
Readout of the actual address of the DeviceNet
option via dip switch.
Parameter 801:
Readout the transmission speed in bit/sec. The
default setting is 125 kbaud, which means the VLT
automatically detects the transmission speed of the
connected bus. If you set a fixed value it must be
the same as that selected in the master.

Special Attention

Special attention must be given to the following
parameters described in the VLT 5000 Series
Instruction Manual:
• 002:
If operation site = Local, then control via
DeviceNet is not possible.
• 502-508:
Selection of how to gate DeviceNet control
commands with control commands on the digital
inputs of the control card.
• 512:
Selects DeviceNet profile.
• 515-538:
Data read out parameters that can be used to read
various actual data from the VLT, as for example actual
status on the analog and digital inputs of the control
card thus using these as inputs to the master.
801 Baud rate selection
(BAUD RATE SELECT)
Value:
125 kBaud (125 KBAUD)
250 kBaud (250 KBAUD)
500 kBaud (500 KBAUD)
= factory setting. () = display text [] = value for use in communication via serial communication port

8000 AQUA DeviceNet
Function:
This parameter displays the actual Baud rate
of the devicenet option.
803 Time after bus error
(BUS TIME OUT)
Value:
1 - 99 sec
804 Response after bus error
(TIME OUT FUNCT.)
Value:
Off (OFF)
Freeze output frequency (FREEZE OUTPUT)
Stop with auto restart (STOP)
Output frequency = JOG frequency (JOGGING)
Output frequency = Max. freq. (MAX SPEED)
Stop with trip (STOP AND TRIP)
Control without DeviceNet (NO DEVICENET CONTROL )
Select set up 4 (SELECT SETUP 4)
Function:
The time out counter is triggered at the first reception
of a valid control word i.e. bit 10 = ok.
1. CTW is not updated within the specified time
2. Parameter 805 = "bit 10 = 0
and bit 10 = "0"
The VLT remains in the timeout state until one of
the following four conditions occurs:
1. Valid control word (Bit 10 = ok) is received and reset
(Bus, terminals or local control panel) is activated
(reset is only necessary when the time out function
Stop w/trip is selected)
is resumed with the actual control word
2. Parameter 002 = Local
local control panel is enabled.
3. Parameter 928 = Disabled
terminals and RS485 is enabled.
4. Parameter 804 = Off
is resumed, with the control word used
last being taken.
NB!:
The time out counter is reset and needs to
[20]
be triggered by a valid control word before
[21]
a new timeout can be activated
