Under voltage of control voltage
Power supply switched on? Power supply o.k ?
internal fuse o.k.? control voltage < 17 V
off
off
Under voltage in DC-bus < Ua low threshold
check power supply (power supply unit, wiring,
fuse), check under voltage parameter

feedback system error (e.g. resolver)
wiring to encoder system ok?
encoder system supply ok?

I²t- overload of the drive
does the control loop oscillate?
P-amplification too high mechanics stiff?
requirements too high? is warning /8/ evaluated?

Reaction to these errors chapter:
Function diagrams from inputs and outputs

With configuration corresponding chapter :
Operating modes and pin functions
3)
Only warning respect. status indicator
The error signals are shown as long as there is control voltage (Us), also when the power (DC-Bus)
is switched off for safety reasons.
