VLT AutomationDrive FC 301/302
Function:
The motor runs at reference speed. No
warnings.
An alarm activates the output. No
warnings.
An alarm or a warning activates the
output.
The torque limit set in
parameter 4-16 Torque Limit Motor
Mode or parameter 4-17 Torque Limit
Generator Mode has been exceeded.
The motor current is outside the range
set in parameter 4-18 Current Limit.
The motor current is lower than set in
parameter 4-50 Warning Current Low.
The motor current is higher than set in
parameter 4-51 Warning Current High.
Output speed/frequency is outside the
frequency range set in
parameter 4-52 Warning Speed Low and
parameter 4-53 Warning Speed High.
Output speed is lower than the setting
in parameter 4-52 Warning Speed Low.
Output speed is higher than the
setting in parameter 4-53 Warning
Speed High.
Feedback is outside the range set in
parameter 4-56 Warning Feedback Low
and parameter 4-57 Warning Feedback
High.
Feedback is below the limit set in
parameter 4-56 Warning Feedback Low.
Feedback is above the limit set in
parameter 4-57 Warning Feedback High.
Thermal warning turns on when the
temperature exceeds the limit either in
motor, frequency converter, brake
resistor, or connected thermistor.
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.
operation and the mains voltage is
within the specified voltage range (see
the General Specifications section in the
design guide).
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.

5-40 Function Relay
Option: Function:
[26] Bus OK Active communication (no timeout) via
the serial communication port.
[27] Torque limit & Use for performing a coasted stop in a
stop torque limit condition. If the frequency
converter has received a stop signal
and is in torque limit, the signal is
logic 0.
[28] Brake, no brake Brake is active and there are no
war warnings.
[29] Brake ready, no Brake is ready for operation and there
fault are no faults.
[30] Brake fault (IGBT) 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 main voltage from the frequency
converter.
[31] Relay 123 Digital output/relay is activated when
[0] Control Word is selected in
parameter group 8-** Comm. and
Options.
[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. Usually solved by
connecting an external relay to the
selected digital output.
NOTICE
[33] Safe stop active
This option is applicable for FC
302 only.
Indicates that the Safe Torque Off on
terminal 37 has been activated.
[36] Control word bit Activate relay 1 by control word from
11 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.
[37] Control word bit Activate relay 2 (FC 302 only) by
12 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.
[38] Motor feedback Failure in the speed feedback loop
error from motor running in closed loop.
The output can eventually be used to
