VLT AutomationDrive FC 301/302
Function:
NOTICE
This option is applicable for FC
302 only.
Indicates that the Safe Torque Off
on terminal 37 has been activated.
Activate relay 1 by control word
from fieldbus. No other functional
impact in the frequency converter.
Typical application: Controlling
auxiliary device from fieldbus. The
function is valid when [0] FC profile
in parameter 8-10 Control Word
Profile is selected.
Activate relay 2 (FC 302 only) by
control word from fieldbus. No
other functional impact in the
frequency converter. Typical
application: Controlling auxiliary
device from fieldbus. The function
is valid when [0] FC profile in
parameter 8-10 Control Word Profile
is selected.
Failure in the speed feedback loop
from motor running in closed loop.
The output can eventually be used
to prepare switching the frequency
converter in open loop in an
emergency case.
When the difference between
calculated speed and actual speed
in parameter 4-35 Tracking Error is
larger than selected, the digital
output/relay is active.
Active when the actual speed is
outside the settings in
parameter 4-52 Warning Speed Low
to parameter 4-55 Warning Reference
High.
Active when the actual speed is
below speed reference setting.
Active when actual speed is above
speed reference setting.
Controls digital output/relay via
bus. The state of the output is set
in parameter 5-90 Digital & Relay Bus

5-40 Function Relay
Option: Function:
Control. The output state is retained
in the event of bus timeout.
[46] Bus ctrl, 1 if Controls output via bus. The state
timeout of the output is set in
parameter 5-90 Digital & Relay Bus
Control. If a bus timeout occurs, the
output state is set high (on).
[47] Bus ctrl, 0 if Controls output via bus. The state
timeout of the output is set in
parameter 5-90 Digital & Relay Bus
Control. If a bus timeout occurs, the
output state is set low (Off).
[50] On Reference
[51] MCO
Active when a VLT
controlled
Cascade Controller MCO 102 or
VLT
connected. The output is controlled
from option.
[60] Comparator 0 See parameter group 13-1*
Comparators. If comparator 0 in SLC
is true, the output goes high.
Otherwise, it is low.
See parameter group 13-1*
[61] Comparator 1
Comparators. If comparator 1 in SLC
is true, the output goes high.
Otherwise, it is low.
[62] Comparator 2 See parameter group 13-1*
Comparators. If comparator 2 in SLC
is true, the output goes high.
Otherwise, it is low.
[63] Comparator 3 See parameter group 13-1*
Comparators. If comparator 3 in SLC
is true, the output goes high.
Otherwise, it is low.
[64] Comparator 4 See parameter group 13-1*
Comparators. If comparator 4 in SLC
is true, the output goes high.
Otherwise, it is low.
[65] Comparator 5 See parameter group 13-1* Smart
Logic Control. If comparator 5 in SLC
is true, the output goes high.
Otherwise, it is low.
[70] Logic rule 0 See parameter group 13-4* Smart
Logic Control. If logic rule 0 in SLC is
true, the output goes high.
Otherwise, it is low.
[71] Logic rule 1 See parameter group 13-4* Smart
Logic Control. If logic rule 1 in SLC is
true, the output goes high.
Otherwise, it is low.
