Output speed is higher than the
setting in 4-53 Warning Speed High.

4-57 Warning Feedback High.
Feedback is below the limit set in
4-56 Warning Feedback Low.
Feedback is above the limit set in
4-57 Warning Feedback High.
Thermal warning turns on when the
temperature exceeds the limit either

Frequency converter is ready for
operation and is in Auto On mode.
There is no over-temperature

Frequency converter is ready for
operation and the mains voltage is
within the specified voltage range
(see General Specifications section in
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.

Function:
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.
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* 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.
