5.4.2 Maximum current reached,
When the output current has reached the maximum current limit
which is programmed C022, the red LED on the keypad is
illuminated and the assigned output sends a message.
In of overload, the output frequency is automatically reduced
to prevent a rising of the motor current. You
also use the maximum current limit, to accelerate the drive
at the set maximum current limit. The motor then generates a
torque up to its rated frequency.

you set the chopper frequency to a fixed value of 12 or 16 kHz, the
current limit is reduced internally to a permissible value. For setting
the chopper frequencies see page 96.

5.4.4 Fault TRIP
A fault is indicated via the permanently assigned digital output
terminal 41 and in factory setting via the relay output. you need
the output terminal 41 with reverse polarity, you have to use a freely
assignable output and set the polarity as required. Before, the relay
output must be assigned to another
5.4.5 Ready, RDY
The “ready” is indicated approximately 0.5 seconds after
mains connection by the illuminated green LED on the keypad and
via the digital output terminal 44.
If you need the permanently assigned output terminal 44 with
inverted polarity you must use a freely assignable output and set
the polarity as required.
In of a warning (see page 150) the “ready” is cancelled
without the being inhibited.
