Ready signal
The “Ready” signal is output when the inverter is enabled (P24V at
terminals X11.10). The additional signaling relay, ready (terminals
X52.7/8) has a lower priority, and does not have to be evaluated.
If a signal is not output, the causes can be as follows:
Cause
Remedy
The DC link voltage is either not
present, is too high or too low
Check the wiring;
force the “Run” mode
if a high dynamic regenerative
feedback power is the cause.
The line supply is either not present, is
too high or too low
Check the wiring and fuses, measure
the line supply voltage
Heatsink temperature too high
Ensure that the air intake is not
restricted
