Mains Voltage - Lenze i55AE125B Manual

Basic setting

Mains voltage

7.1 Mains voltage
The rated mains voltage set for the inverter has an impact on the operating range of the inver-
ter.
Details
By default, the rated mains voltage in
code of the inverter.
Check the setting of the rated mains voltage in
that it matches the actual mains voltage applied!

Notes regarding the table:
The inverter types 400/480 V can be used with different mains voltages. For setting the
•
internal limit values, the rated mains voltage can be set in
user.
The inverter types 120 V are designed for a 1-phase 120-V mains voltage and 3-phase 230-
•
V three-phase AC motors. These inverters have an internal DC bus similar to the 230-V
inverters. The voltage thresholds correspond to the ones of the 230-V inverters.
If the inverter is reset to the delivery status, the rated mains voltage is also reset to the
•
default setting listed in the table according to the product code.
The following results from the rated mains voltage set:
the error threshold for monitoring the DC-bus voltage and
•
the voltage threshold for braking operation ("brake chopper threshold").
•
Monitoring of the DC-bus voltage
The warning thresholds for monitoring are adjustable.

If the DC-bus voltage of the inverter falls below the undervoltage error threshold, the
•
"Trouble" response is triggered.
Without external 24-V supply: Motor behaves according to

With external 24-V supply: At undervoltage, motor behaves according to disturbance

response.
If the DC-bus voltage of the inverter exceeds the overvoltage error threshold, the "Fault"
•
response is triggered.
The motor does not restart automatically after the overvoltage monitoring func-
tion has been activated.
