ALSTOM ALSPA MV1000 Intelligent Variable Frequency Drive

Multi motor application support: ALSPA MV1000 can drive both single motors and multi motor drive systems. Four quadrant operation is achieved through DC braking, braking chopper, common DC bus, or energy feedback to the power grid.

Communication Capability: Connecting Future Factories

Modern automation cannot do without powerful communication networks. ALSPA MV1000 also performs well in this regard:

Standard interface:

Terminal block: Provides 6 digital inputs (5 configurable), 4 parameter adjustable digital outputs, 2 expandable analog reference inputs (differential input, -10V...+10V, one of which can also be set to 0 (4)... 20mA), and 2 expandable analog outputs.

CAN bus interface: As a standard configuration, it supports connecting CAL and CANopen devices.

Incremental encoder input: Supports encoder signals up to 500kHz.

Motor PTC connection: used for winding overheating protection.

Optional fieldbus coupler: By replacing the keyboard or PC interface module, various mainstream fieldbus can be integrated, including FIP, Profibus DP, Interbus S, Modbus Plus, Bitbus, and easily integrated into various automation systems.

DC system bus: ALSPA MV1000 is equipped with DC bus terminals, which can achieve energy sharing and power demand reduction among multiple inverters, especially suitable for multi drive applications.

User Interface: Keyboard and PC Software

Smart keyboard: The keyboard is the interaction window between the operator and the driver. It is equipped with:

Clear structured menu

Two line plain text LCD display screen

Running status LED indicator light

Run/stop and motor potentiometer buttons

4 cursor keys for parameter adjustment and status query

The keyboard can be clipped onto the drive and can save and copy parameters to another ALSPA MV1000, greatly facilitating batch debugging and maintenance.

PC software ALSPAPCS: runs on Microsoft Windows ™ In the environment, provide stronger support:

Guided debugging, operation guidance, and monitoring

The virtual oscilloscope function can display the waveform of any internal control variable, and the data can be saved, printed, and annotated

Save and transfer the complete parameter set, significantly reducing system debugging time

Monitor and control multiple devices simultaneously through a serial PC interface

Debugging and service work can be completed without the need for an external oscilloscope
