Frequency converter is ready for
operation and no over-temperature
warning is present.
Frequency converter is ready for
operation in Auto mode, and no over-
temperature warning is present.
operation and mains voltage is within
specified voltage range.
Motor runs/is ready to run clockwise
when logic = 0 and counter clockwise
when logic = 1. Output changes as
soon as reversing signal is applied.
Active communication (no time-out) via
serial communication port.
Brake is active, and no warnings are
present.
Brake is ready for operation, and no
faults are present.
Protects frequency converter if fault on
brake modules is present. Use relay to
cut out main voltage from frequency
converter.
Enables control of external mechanical
brake, see parameter group 2-2*
Mechanical Brake.
Bit 11 in control word controls relay.
Reference is lower than set in 4-54
Warning Reference Low.
Reference is higher than set in 4-55
Warning Reference High.

Set 5-15 Terminal 33 Digital Input to choice [32] pulse input.
Now terminal 33 handles a pulse input in the range from
Low frequency, 5-55 Terminal 33 Low Frequency, to 5-56
