Use of the relay for 230 V AC brake
Par. 302 Digital input = Start [7]
Par. 304 Digital input = Coasting stop inverted [2]
Par. 323 Relay output = Mechanical
brake control [25]
See also par. 138, 139, 140
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 .
NOTE
Do not use the internal relay for DC brakes
or brake voltages > 250 V.
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 frequency converter.
Par. 307 Digital input = Pulse input [30]
Par. 343 Precise stop function = Counter
stop with reset [1]
Par. 344 Counter value = 100000
