main power to the unit is not detected.
The frequency converter is ready for
operation and applies a supply signal on
the control board.
The frequency converter is ready for
operation and is in auto-on mode.
Ready for operation. No start or stop
command has been given (start/disable).
No warnings are active.
The motor runs and shaft torque is
present.
The output speed is higher than the
speed set in parameter 1-81 Min Speed for
Function at Stop [RPM]. The motor runs
and there are no warnings.
Motor runs within the programmed
current and speed ranges set in
parameter 4-50 Warning Current Low to
parameter 4-53 Warning Speed High. There
are no warnings.
Motor runs at reference speed. No
warnings.
An alarm activates the output. There are
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.
Motor current is lower than set in
parameter 4-50 Warning Current Low.
Motor current is higher than set in
parameter 4-51 Warning Current High.
Output frequency is outside the

[22] Ready, no Frequency converter is ready for
thermal operation, and there is no overtem-

[23] Remote, ready, Frequency converter is ready for
no thermal operation and is in auto-on mode. There

[24] Ready, no over/ Frequency converter is ready for
undervoltage operation and the mains voltage is within
the specified voltage range (see the
section General Specifications in the
frequency converter design guide).
[25] Reverse The motor runs (or is ready to run)
clockwise when logic = 0 and counter-
clockwise when logic = 1. The output
changes when the reversing signal is
applied.
[26] Bus OK Active communication (no timeout) via
the serial communication port.
[27] Torque limit Use in performing a coast stop and in
and stop torque limit condition. If the frequency
converter has received a stop signal and
is at the torque limit, the signal is logic 0.

[30] Brake fault Output is logic 1 when the brake IGBT is
(IGBT) short-circuited. Use this function to
protect the frequency converter if there is
a fault on the brake modules. To cut out
the main voltage from the frequency
converter, use the output/relay.
