Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Vacon NXP03855A0N0SSAA1A2A500C5 is an air-cooled AC frequency inverter within the Vacon NXP series, built for heavy-duty motor control applications. Operating from a 380 V AC to 500 V AC three-phase supply, this Frame Size FR9 drive housed in an IP20 enclosure supplies up to 385 A continuous output current (200 kW) under low overload conditions, or 300 A continuous output current (160 kW) under heavy-duty ratings. It supports open-loop, closed-loop vector control, and frequency (V/Hz) control modes, making it suitable for continuous high-torque industrial machinery, mixers, extruders, pumps, and fans.
Integration and commissioning rely on a modular five-slot card system pre-configured with dedicated control, feedback, and communication modules. Slot A contains the OPTA1 standard I/O card (6 digital inputs, 2 analog inputs, 1 digital output, 1 analog output), Slot B holds the OPTA2 card (2 relay outputs, 1 thermistor input), Slot C houses the OPTA5 HTL encoder card for closed-loop motor feedback, and Slot E contains the OPTC5 PROFIBUS DP interface board. Commissioning a replacement unit involves transferring saved parameter sets, which are maintained in non-volatile EEPROM/Flash memory and can be copied via the removable keypad module or configured through Vacon Live and NCDrive engineering tools. ABC Industrial Parts provides assistance with unit selection, parameter backup, and donor drive setup.
System state and fault tracking are available on the six-line alphanumeric keypad display, supplemented by four dedicated front panel status indicators for ready, run, fault, and alarm conditions. The internal Fault History Menu (M8) records the last 30 trip events with associated timestamps and operating values, while fieldbus status registers transmit real-time diagnostics over PROFIBUS DP. First-line troubleshooting involves checking input line fuses, main supply symmetry, power cable shielding, encoder signal integrity, and verifying board seating in slots A through E. When severe internal hardware or power stage trips occur, ABC Industrial Parts can support rapid turnaround with replacement units or specialist repair services to minimize system downtime.

Programming and Configuration
Parameterization and monitoring for the Vacon NXP03855A0N0SSAA1A2A500C5 are managed using the removable alphanumeric keypad display or PC engineering packages including Vacon Live and NCDrive. Operational configurations, motor nameplate values, control curves, and custom I/O mappings are written directly to non-volatile EEPROM/Flash storage on the drive control board, preventing data loss during total power interruption.
When replacing an existing drive, the keypad parameter copy feature allows complete parameter sets to be uploaded from an operating drive into the keypad memory and downloaded into a spare unit. Alternatively, parameter files can be uploaded, stored, and commissioned using Vacon Live software over a direct serial connection. Automatic option board recognition immediately detects cards in option slots A through E upon startup, though hardware profile or board model changes require acknowledgment via a panel parameter reset.
Communication and System Integration
Network integration for the NXP03855A0N0SSAA1A2A500C5 drive is achieved using the pre-installed OPTC5 PROFIBUS DP fieldbus card located in option Slot E. This interface enables high-speed cyclical communication with host PLCs, allowing control word commands, speed references, and status word monitoring to pass directly across the PROFIBUS bus.
In addition to fieldbus integration, this build configuration includes three internal I/O and feedback option cards across slots A, B, and C. Slot A houses the OPTA1 board providing 6 digital inputs, 2 analog inputs, 1 digital output, and 1 analog output. Slot B includes the OPTA2 card with 2 programmable relay outputs and a thermistor input for direct motor thermal protection. Slot C contains the OPTA5 HTL incremental encoder card, supporting 10-30V encoder feedback signals to execute closed-loop vector control and precise speed feedback.
Diagnostics and Status Indication
The drive provides continuous diagnostic output via its 6-line control panel display, local status LEDs, and digital fieldbus diagnostic registers. Front-panel LED indicators display the fundamental operational state, identifying power presence, modulating status, active warnings, or fault trips instantly.
Detailed fault logging is recorded automatically in the Fault History Menu (M8), which stores up to 30 sequential fault records accompanied by timestamp markers, operating frequency, output current, and DC-link voltage at the moment of tripping. Diagnostic parameter values can also be monitored live or saved using Vacon Live and NCDrive software tools.

| RUN | Green - Solid | Drive running and modulating motor output |
| FAULT | Red - Solid/Flashing | Drive stopped due to active fault condition |
| ALARM | Yellow - Solid/Flashing | Active warning/alarm condition, drive continues running |
Replacement and Spare Part Considerations
When swapping out a Vacon NXP03855A0N0SSAA1A2A500C5 drive, it is essential to ensure that the replacement unit shares the exact hardware option card allocation. This specific model code specifies pre-installed option boards in Slot A (OPTA1 I/O), Slot B (OPTA2 Relay/Thermistor), Slot C (OPTA5 HTL Encoder), and Slot E (OPTC5 PROFIBUS DP). If a replacement unit lacks any of these boards, hardware fault codes such as F26, F37, F39, or F54 will occur.
Mechanical and electrical matching requires confirmation of the FR9 frame size dimensions, IP20 protection class, and 380-500 V AC input supply ratings. Prior to powering up the motor on a replacement unit, motor parameter configurations and encoder feedback settings must be uploaded using the keypad parameter copy feature or software tools (Vacon Live or NCDrive) to ensure proper vector control and speed scaling.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
