(Relay 1 [0], Relay 2 [1], Relay 3 [2] (MCB 113), Relay 4 [3] (MCB
113), Relay 5 [4] (MCB 113), Relay 6 [5] (MCB 113), Relay 7 [6]
(MCB 105), Relay 8 [7] (MCB 105), Relay 9 [8] (MCB 105))
Option: Function:
[32] Mech brake ctrl Selection of mechanical brake control.
When selected parameters in
parameter group 2-2* Mechanical
Brake are active. The output must be
reinforced to carry the current for the
coil in the brake. Solved by
connecting an external relay to the
selected digital output.
[33] Safe stop active (FC 302 only) Indicates that the safe
stop on terminal 37 has been
activated.
[36] Control word bit Activate relay 1 via control word from
11 serial communication bus. No other
functional impact in the adjustable
frequency drive. Typical application:
Controlling auxiliary devices from
serial communication bus. The
function is valid when [0] FC profile in
8-10 Control Word Profile is selected.
[37] Control word bit Activate relay 2 (FC 302 only) by
12 control word from serial communi-
cation bus. No other functional
impact in the adjustable frequency
drive. Typical application: controlling
auxiliary device from the serial
communication bus. The function is
valid when [0] FC profile in
8-10 Control Word Profile is selected.
[38] Motor feedb. error Failure in the speed feedback loop
from motor running in closed-loop.
The output can eventually be used to
prepare switching the adjustable
frequency drive in open-loop in the
case of an emergency.
[39] Tracking error When the difference between
calculated speed and actual speed in
4-35 Tracking Error is larger than
selected the digital output/relay is
active.
[40] Out of ref range Active when the actual speed is
outside settings in 4-52 Warning Speed
Low to 4-55 Warning Reference High.
[41] Below reference, Active when actual speed is below
low speed reference setting.

Function:
Active when actual speed is above
speed reference setting.
Controls digital output/relay via bus.
The state of the output is set in
5-90 Digital & Relay Bus Control. The
output state is retained in the event
of bus timeout.
Controls output via bus. The state of
the output is set in 5-90 Digital &
Relay Bus Control. If bus timeout, the
output state is set high (On).
Controls output via bus. The state of
the output is set in 5-90 Digital &
Relay Bus Control. In the event of a
bus timeout, the output state is set to
low (Off).
Active when an MCO 302 or MCO 305
is connected. The output is controlled
from an option.
See parameter group 13-1* Smart
Logic Control. If Comparator 0 in SLC
is true, the output goes high.
Otherwise, it is low.
See parameter group 13-1* Smart
Logic Control. If Comparator 1 in SLC
is true, the output goes high.
Otherwise, it is low.
See parameter group 13-1* Smart
Logic Control. If Comparator 2 in SLC
is true, the output goes high.
Otherwise, it is low.
See parameter group 13-1* Smart
Logic Control. If Comparator 3 in SLC
is true, the output goes high.
Otherwise, it is low.
