Danfoss VLT PROFIBUS DP MCA 101 User Manual

6 Parameters
6.1 8-** PROFIBUS Parameters
This chapter describes the general parameters relating to
PROFIBUS and the communication settings of the
frequency converter.
Not all product series support all parameters, just as the
parameter settings may vary between the product series.
For details of the parameters in parameter groups 8-**
Comm. and Options, 9-** PROFIBUS, and 16-** Data
Readouts, refer to the programming guide of the
specic
product series.
8-01 Control Site
Option: Function:
The setting in this parameter overrides the
settings in parameter 8-50 Coasting Select to
parameter 8-56 Preset Reference Select.
[0] Digital and
ctrl.word
Control by using both digital input and
control word.
[1] Digital only Control by using digital inputs only.
[2] Controlword
only
Control by using control word only.
8-02 Control Word Source
Option: Function:
NOTICE
This parameter cannot be adjusted
while the motor is running.
Select the source of the control word: 1 of 2
serial interfaces or 4 installed options. During
initial power-up, the frequency converter
automatically sets this parameter to [3] Option
A if it detects a valid
eldbus option installed
in slot A. When the option is removed, the
frequency converter detects a conguration
change, sets parameter 8-02 Control Word
Source to default setting [1] FC RS485, and
trips. If an option is installed after initial
power-up, the setting of
parameter 8-02 Control Word Source does not
change, but the frequency converter trips and
shows: Alarm 67, Option Changed.
When retrotting a bus option into a
frequency converter that did not have a bus
option installed earlier, change the control to
bus-based. This change is required for safety
reasons to avoid an unintended change.
[0] None
[1] FC RS485
[2] FC USB
8-02 Control Word Source
Option: Function:
[3] Option A
[4] Option B
[5] Option C0
[6] Option C1
[30] External Can
8-03 Control Word Timeout Time
Range: Function:
1 s* [ 0.1 -
18000 s]
Enter the maximum time expected to pass
between the reception of 2 consecutive
telegrams. If this time is exceeded, it indicates
that the telegram communication has stopped.
The function selected in parameter 8-04 Control
Word Timeout Function is then carried out. A
valid control word triggers the timeout counter.
8-04 Control Word Timeout Function
Select the timeout function. The timeout function activates when
the control word fails to be updated within the time period
specied in parameter 8-03 Control Word Timeout Time.
Option: Function:

congure as follows:
1. Set parameter 0-10 Active Set-
up to [9] Multi set-up.
2. Select the relevant link in
parameter 0-12 This Set-up
Linked to.
[0] O Resumes control via eldbus (eldbus or
standard), using the most recent control word.
[1] Freeze
output
Freezes output frequency until communication
resumes.
[2] Stop Stops with auto restart when communication
resumes.
[3] Jogging Runs the motor at jog frequency until
communication resumes.
[4] Max. speed Runs the motor at maximum frequency until
communication resumes.
[5] Stop and
trip
Stops the motor, then resets the frequency
converter to restart:
•
Via the eldbus.
•
Via [Reset].
•
Via a digital input.
