There is no over-temperature warning.
Frequency converter is ready for
operation and the mains voltage is
within the specified voltage range
(see General Specifications section in
Design Guide).
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.

has received a stop signal and is in
torque limit, the signal is Logic '0'.

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/
