Additional parameters
Parameter Default Set to Function
P0003
Access level
13
Allows the user to have a higher access level
The following parameters require level 3 access, unless stated otherwise
P1200
Flying restart
01
Allows motor to start into a spinning load
E.g. fan being turned by the air flow
P0295 (access level 4)
VSD fan off delay
time
0
30-
3600 s
Defines VSD internal fan switch off delay time (after VSD has stopped)
Set P0003 to 4, set P3950 to 46, then set P0295 to the time required in
seconds
P1210
Automatic restart
12
Allows VSD to start after a power cut
Auto restart requires constant on command (e.g. via a digital input)
P0010
P0970
Reset to
factory defaults
0
0
30
1
This allows the VSD to be reset to factory defaults
The following parameters retain their values after a factory reset:
P0918 (CB address), P2010 (USS Baud rate),
P2011 (USS address)
7 Application examples
7.1 Application example 1
The speed of a motor shall be controlled via the motor’s potentiometer (hand) or using a analog signal via
an external control signal DC 0...10 V within the frequency range of 0...50 Hz.
− ON and OFF via the digital input
− Error message via relay output 1
− Indication of operation via relay output 2
Note: With the settings for this application example, the assumption is made that the parameters use their de-
fault values and that the connected motor has been commissioned with the standard parameters.
