Function:
The feedback is below the limit set in
parameter 4-56 Warning Feedback Low.
The feedback is above the limit set in
parameter 4-57 Warning Feedback High.
Thermal warning turns on when the
temperature exceeds the limit within
the motor, frequency converter, brake
resistor, or connected resistor.
The frequency converter is ready for
operation and there is no overtem-
perature warning.
The frequency converter is ready for
operation and is in Auto On mode.
There is no overtemperature warning.
The frequency converter is ready for
operation, and the mains voltage is
within the specified voltage range.
The motor runs (or is ready to run)
clockwise when logic=0 and counter-
clockwise when logic=1. The output
changes as soon as the reversing signal
is applied.
Active communication (no timeout) via
the serial communication port.
Use for performing a coasted stop for
frequency converter in torque limit
condition. If the frequency converter
has received a stop signal and is in
torque limit, the signal is logic=0.
The brake is active and there are no
warnings.
The brake is ready for operation and
there are no faults.
The output is logic=1 when the brake
IGBT is short-circuited. Use this
function to protect the frequency
converter if there is a fault on the
brake module. Use the digital output/
relay to cut out the mains voltage from
the frequency converter.
Digital output/relay is activated when
[0] Control word is selected in
parameter group 8-** Comm. and
Options.
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. This issue is solved by

5-40 Function Relay
Option: Function:
connecting an external relay to the
selected digital output.
[36] Control word bit Activate relay 1 by a control word from
11 the fieldbus. No other functional
impact on the frequency converter.
Typical application: Controlling an
auxiliary device from a fieldbus. The
function is valid when [0] FC Profile is
selected in parameter 8-10 Control Word
Profile.
[37] Control word bit Activate relay 2 by a control word from
12 the fieldbus. No other functional
impact on the frequency converter.
Typical application: Controlling an
auxiliary device from a fieldbus. The
function is valid when [0] FC Profile is
selected in parameter 8-10 Control Word
Profile.
[40] Out of ref range Active when the actual speed is
outside the settings in
parameter 4-55 Warning Reference High
and parameter 4-56 Warning Feedback
Low.
[41] Below reference, Active when the actual speed is below
low the speed reference setting.
[42] Above ref, high Active when the actual speed is above
the speed reference setting.
[45] Bus ctrl. Controls the digital output/relay via
bus. The state of the output is set in
parameter 5-90 Digital & Relay Bus
Control. The output state is retained in
the event of a bus timeout.
[46] Bus control, Controls output via bus. The state of
timeout: On the output is set in
parameter 5-90 Digital & Relay Bus
Control. When a bus timeout occurs,
the output state is set high (on).
[47] Bus control, Controls output via bus. The state of
timeout: Off the output is set in
parameter 5-90 Digital & Relay Bus
Control. When a bus timeout occurs,
the output state is set low (off).
[56] Heat sink
cleaning warning,
high
[60] Comparator 0 See parameter group 13-1* Smart Logic
Control. If comparator 0 in SLC is TRUE,
the output goes high. Otherwise, it
goes low.
[61] Comparator 1 See parameter group 13-1* Smart Logic
Control. If comparator 1 in SLC is TRUE,
