Monitoring bus voltage
The bus voltage is monitored by the DSP (Process) directly. As soon as the bus voltage is too low or too high, the
machine will stop and displays the corresponding error message:
E22
: Mains undervoltage 1
E23
: Mains overvoltage
E30
: Mains undervoltage 2
Should the mains voltage be too low at both power units (only at V40 or V50), only the error message with the
highest number is displayed (
E30
).
