ABB ACS800 Standard Control Procedure 7. x

Product Overview

Scope of application: The firmware manual for the standard control program of ACS800 frequency converter is suitable for motor drive control in the field of industrial automation, supporting multiple control modes and communication protocols.

Core functions: including startup configuration, control panel operation, parameter setting, fault diagnosis, communication interface, and various application macros (such as factory macros, PID control macros, torque control macros, etc.).

Startup and control mode

Start the process

Startup Wizard: Guide users to complete motor parameter settings (such as voltage, current, frequency, etc.) and identification run (ID Run), supporting both standard and simplified identification modes to ensure motor control accuracy.

Basic startup: Manually input parameters, suitable for quick configuration scenarios without the need for a wizard.

control model 

Local control: Directly operated through the control panel, supporting start, stop, steering, and speed settings.

External control: Receive commands through digital/analog inputs or fieldbus (such as PROFIBUS, Modbus), supporting dual control switching between EXT1 and EXT2.

Core functional modules

Program Function

Given signal processing: supports multi-source given signals such as analog input, digital input, fieldbus, etc., and can combine given signals through mathematical operations (such as addition, subtraction, multiplication, division, and taking the maximum value).

Speed and torque control:

Speed control: supports PID regulation, acceleration/deceleration ramp setting, and dangerous speed avoidance.

Torque control: Suitable for scenarios that require precise torque output, such as elevators and conveyor belts.

Braking control: Supports DC brake, magnetic flux brake, and mechanical brake, with configurable braking delay and torque threshold.

Application Macro Program

Factory macro: default mode, suitable for general speed control scenarios, supports 3 constant speed options.

PID control macro: used for process control (such as pressure and flow closed-loop), integrating sleep function to optimize energy consumption.

Torque control macro: directly controls motor torque, supports switching with speed control mode.

User macro: allows storage of two sets of custom parameters, facilitating quick switching between different motors or operating conditions.

Communication and Interface

Fieldbus support: compatible with protocols such as PROFIBUS, Modbus RTU/TCP, PROFINET, etc., and supports redundant communication configurations.

I/O expansion module: can connect digital/analog expansion modules, expand input and output channels, support motor temperature measurement, encoder interface, etc.

Parameters and actual signals

Parameter group division:

Startup data (99 sets): motor nameplate parameters, control mode, identification of operating configuration.

Given options (11 groups): Define the source of speed/torque given (such as analog input, fieldbus).

Limit values (20 sets): Setting operating limits such as speed, current, torque, etc.

Fault function (30 sets): Protection parameters for overcurrent, overvoltage, underload, etc., supporting automatic reset and alarm threshold setting.

Actual signal monitoring: Real time display of speed, current, torque, DC bus voltage, etc., supporting custom display combinations and filtering processing.

Fault diagnosis and maintenance

Fault codes and reset

Locate faults through control panel LED indicators or fault codes (such as overcurrent, overheating, communication interruption), and support manual or automatic reset (parameter configuration required).

Fault records store the last 6 events, including timestamps and fault types, to assist in quick troubleshooting.

Maintenance suggestions

Regularly check the matching of motor parameters, encoder connections, and the operating status of the cooling fan.

The communication module should pay attention to grounding and anti-interference, and avoid parallel wiring of high-voltage lines and signal lines.

Safety and Standards

Electrical safety: Ensure that grounding complies with NEC standards, avoid modifying parameters with motors, and prevent accidental start-up.

Electromagnetic compatibility (EMC): Sensor cables need to be shielded and grounded at one end, and isolated from high-voltage lines.

Compliance certification: Complies with IEC standards and supports explosion-proof applications in hazardous environments (requires corresponding module configuration).
