On the front of the compact inverters are several LEDs for functional control,
with the following meaning:
Meaning
Reset signal from LE, CC to UE
U too low, U < 410 V (e.g. failure of a
Z Z
phase under load, power < 290 V)
Reset signal from UE to LE, CC
Inverter ready
Temperature of heat sink too high (> 100
°C)
U too high (> approx. 850 V); power
Z
modules are switched off
Main contactor on
Safety relay for spindle on
Safety relay for axes on
Safe stop 1; no enable from control (main
contactor not active, DSP error, PLC error
with Emergency Stop, hardware or
software error of LE, CC)
Axis/Spindle enabled
Safe stop 2; no drive enable from control
(e.g. by the PLC, active via external signal
