no display
any control voltage? external fuses ok?
system ready to operate
drive ready, not active
drive ready to operate!
DC link voltage within the limits,
power stage active, fault-free
internal STOP with serial deactivating
activate drive via serial interface
regulator of serial interface (bus interface) deactivated !
only if bus interface is integrated
deactivated with delay time for the brake
deactivated via input
deactivated via serial command.
Active input is activated with switching on
24V control voltage
switch enable X10.xx switch on 0V and
after that 24V
Under voltage of control voltage
Power supply switched on? Power supply o.k ?
internal fuse o.k.? control voltage < 17 V
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
1)
With configuration corresponding chapter : Operating modes and pin functions
2)
Only warning respect. status indicator
3)
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.
Many faults can be corrected by using the diagnostic display.
