Danfoss VLT FCD 311 Design Manual page 46

Par. 200 Output frequency range = Both direc-
tions, 0-132 Hz [1]
Par. 203 Reference range = Min. ref. - Max. ref.
[0]
Par. 204 Min. reference = - 50 Hz
Par. 205 Max. reference = 50 Hz
Par. 302 Digital input = Start [7]
Par. 304 Digital input = Coasting stop inverted [2]
Par. 308 Analogue input = Reference [1]
Par. 309 Terminal 53, min. scaling = 0 Volt.
Par. 310 Terminal 53, max. scaling = 10 Volt.
Preset references
Switch between 8 preset references via two digital
inputs and Setup 1 and Setup 2.
Par. 004 Active Setup = Multisetup 1 [5]
Par. 204 Min. reference = 0 Hz
Par. 205 Max. reference = 50 Hz
Par. 302 Digital input = Start [7]
Par. 303 Digital input = Choice of Setup, lsb [31]
Par. 304 Digital input = Coasting stop inverted [2]
Par. 305 Digital input = Preset ref., lsb [22]
Par. 307 Digital input = Preset ref., msb [23]
Setup 1 contains the following preset references:
Par. 215 Preset reference 1 = 5.00%.
Par. 216 Preset reference 2 = 10.00%.
Par. 217 Preset reference 3 = 25.00%.
Par. 218 Preset reference 4 = 35.00%.
Setup 2 contains the following preset references:
Par. 215 Preset reference 1 = 40.00%.
Par. 216 Preset reference 2 = 50.00%.
Par. 217 Preset reference 3 = 70.00%.
Par. 218 Preset reference 4 = 100.00%.

Connection of mechanical brake
Use of the relay for 230V AC brake
Par. 302 Digital input = Start [7]
Par. 304 Digital input = Coasting stop inverted [2]
Par. 323 Relay output = Mechanical brake control
[25]
Mechanical brake control [25] = '0' => Brake is
closed.
Mechanical brake control [25] = '1' => The brake is
open.
See more detailed parameter settings under Control
of mechanical brake.
Counter stop via terminal 33.
The start signal (terminal 18) must be active, i.e.
logical '1', until the output frequency is equal to the
reference. The start signal (terminal 18 = logical '0')
must then be removed before the counter value in
parameter 344 has managed to stop the VLT fre-
quency converter.
