i950

The intelligent i950 cabinet servo inverter can be easily integrated into modular machine solutions on the basis of prepared technology applications - parameterization instead of programming.
The same architecture, the same engineering and the use of the same application software, based on decades of application experience, dissolve the boundaries between centralized and decentralized motion control. Our FAST Application Software Toolbox becomes universally usable. If required, the pre-designed software modules can be very easily customized and extended.
In addition, the i950 cabinet servo inverter serves as a power extension of the i750 cabinet servo inverter in the Lenze automation system in the range from 22 to 110 kW.
The requirements of the Ecodesign Directive, Standard EN IEC 61800-9-2, are met.

Documentation

Error codes

Fault ID: 12816

Hex: 0x3210

Description: Fault - DC bus overvoltage

Keypad display: DC Bus OV
Cause	Remedy	Severity/response
DC-bus voltage has exceeded the error threshold for overvoltage due to a too high braking energy or a too high mains voltage. The error threshold (display in 0x2540:006 (P208.06) results from the setting of the rated mains voltage in 0x2540:001 (P208.01).	Reduce dynamic performance of the load profile. Check mains voltage. Check settings for brake energy management. 0x2541:001 (P706.01) = [0]: Connect brake resistor to the power unit and activate the integrated brake chopper	Fault

Fault ID: 12672

Hex: 0x3180

Description: UPS operation active

Keypad display: UPS oper. active
Cause	Remedy	Severity/response
Operation on uninterrupted 1x230V current supply (UPS) has been activated: Only a reduced output current is provided.	Switch back to operation with regular mains voltage	Warning

Fault ID: 12576

Hex: 0x3120

Description: Mains phase fault 

Keypad display: Mains Phase fail
Cause	Remedy	Severity/response
Mains phase failure	Check wiring of the mains connection. Check fuses.	Fault

Fault ID: 1030

Hex: 1030

Description: Undervoltage in the DC bus

Keypad display: LU
Cause	Remedy	Severity/response
DC bus voltage is lower than specified in C0173.	Check mains voltage Check supply cable	cawc

Fault ID: 1020

Hex: 1020

Description: Overvoltage in DC bus

Keypad display: OU
Cause	Remedy	Severity/response
Braking energy is too high. (DC−bus voltage is higher than set in C0173.)	Use braking unit or regenerative module. Check dimensioning of the brake resistance.
