[5] VLT running Motor is running and shaft torque is
present.
[6] Running / no Output speed is higher than the speed
set in 1-81 Min Speed for Function at Stop
warning
[RPM]. The motor is running and there are
no warnings.
[7] Run in Motor is running within the programmed
range/no current and speed ranges set in
warning 4-50 Warning Current Low to 4-53 Warning
Speed High. There are no warnings.
[8] Run on Motor runs at reference speed. No
reference / no warnings.
warning
[9] Alarm An alarm activates the output. There are
no warnings.
[10] Alarm or An alarm or a warning activates the
warning output.
[11] At torque limit The torque limit set in 4-16 Torque Limit
Motor Mode or 4-17 Torque Limit Generator
Mode has been exceeded.
[12] Out of current The motor current is outside the range
range set in 4-18 Current Limit.
[13] Below current, Motor current is lower than set in
low 4-50 Warning Current Low.
[14] Above current, Motor current is higher than set in
high 4-51 Warning Current High.
[15] Out of speed Output frequency is outside the
range frequency ranges set in 4-52 Warning
Speed Low and 4-53 Warning Speed High.
[16] Below speed, Output speed is lower than the setting in
low 4-52 Warning Speed Low.
[17] Above speed, Output speed is higher than the setting
high in 4-53 Warning Speed High.
[18] Out of Feedback is outside the range set in
feedback range 4-56 Warning Feedback Low and
4-57 Warning Feedback High.
[19] Below Feedback is below the limit set in
feedback low 4-56 Warning Feedback Low.
[20] Above Feedback is above the limit set in
feedback high 4-57 Warning Feedback High.
[21] Thermal The thermal warning turns on when the
warning temperature exceeds the limit in the
motor, the Adjustable frequency drive,
the brake resistor, or the thermistor.
[22] Ready, no Adjustable frequency drive is ready for
thermal operation and there is no over-
warning temperature warning.
[23] Remote, ready, Adjustable frequency drive is ready for
no thermal operation and is in [Auto on] mode.
warning There is no over-temperature warning.

Ready, voltage Adjustable frequency drive is ready for
OK operation and the AC line voltage is
within the specified voltage range (see
General Specifications section in the
Design Guide).
Reverse Reversing. Logic '1' when CW rotation of
the motor. Logic '0' when CCW rotation
of the motor. If the motor is not rotating,
the output will follow the reference.
Bus OK Active communication (no timeout) via
the serial communication port.
Torque limit Use in performing a coasting stop and in
and stop torque limit condition. If the Adjustable
frequency drive has received a stop signal
and is at the torque limit, the signal is
Logic '0'.
Brake, no brake Brake is active and there are no warnings.
warning
Brake ready, no Brake is ready for operation and there are
fault no faults.
Brake fault Output is Logic '1' when the brake IGBT is
(IGBT) short-circuited. Use this function to
protect the Adjustable frequency drive if
there is a fault on the brake modules. Use
the output/relay to cut out the AC line
voltage from the Adjustable frequency
drive.
Relay 123 The relay is activated when Control Word
[0] is selected in parameter group 8-**.
Mechanical Enables control of an external mechanical
brake control brake, see description in the section
Control of Mechanical Brake, and
parameter group 2-2*
Safe stop Indicates that the safe stop on terminal
activated (FC 37 has been activated.
302 only)
Out of ref Active when the actual speed is outside
range settings in 4-52 Warning Speed Low to
4-55 Warning Reference High.
Below Active when actual speed is below speed
reference low reference setting.
Above Active when actual speed is above speed
reference high reference setting
Extended PID
Limit
Bus Ctrl Controls output 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.
Bus Ctrl On at Controls output via bus. The state of the
timeout output is set in 5-90 Digital & Relay Bus
Control. In the event of a bus timeout,
the output state is set high (On).
