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.

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.
