　　Technical specifications and compatibility

　　Control protocol support

Supports fieldbus protocols such as PROFIBUS, and can achieve multi-channel control through analog/digital input terminals, drive control panels and communication modules (such as RPBA-01).

Speed ​​control mode: In PROFIdrive mode, the speed reference value (REF) and the actual value (ACT) correspond to the hexadecimal ratio of 0~4000h, supporting precise adjustment within the rated speed range of the motor.

Control word and status word: Provides functions such as fault reset, inching control, and operating status monitoring, and supports dynamic adjustment of device operation mode.

　　Application scenarios

Applicable to motor control in the industrial automation ecosystem, such as frequency converter speed regulation, inverter power management, etc. Its openness and modular design can adapt to complex industrial needs.

　　Core guidance of user manual

1. Installation and configuration

Physical installation: Insert the optional slot of the drive unit control board to ensure that the connector pins are not bent or damaged.

　　Hardware settings:

Use the rotary switch to set the node address (range 00~99).

DIP switch selects bus terminal mode.

　　Software configuration:

Supported parameters: input/output data, user parameters, diagnostic format.

Maximum periodic data: 28 bytes for input/output, 56 bytes in total.

Maximum non-periodic data: 240 bytes for input/output, 480 bytes in total.

　　2. PROFIBUS communication configuration

Control word (CW) and status word (SW):

Control word: defines motor start/stop, speed setting, etc. (such as ON=0x0001 start, OFF1=0x0002 stop).

Status word: feedback motor status (such as RDY_ON=0x0001 ready, FAULT=0x0008 fault).

　　Parameter mapping:

Speed ​​setting (REF) range: 0~motor rated speed, corresponding to hexadecimal 0h~4000h.

Actual speed (ACT) feedback: same as above.

Environmental and electrical specifications

Working environment: Refer to the “Hardware Manual” for specific temperature/humidity ranges (usually -20°C~60°C).

Power supply requirements: Independent power supply is required to avoid sharing power with high-power equipment.

　　Application areas

Manufacturing automation: Control of motion equipment such as robotic arms, conveyor belts, and turntables.

Process control: Pressure/temperature/flow regulation in petroleum and chemical industries.

New energy: Wind power converter control, solar tracking system drive.

Industrial automation control: Scenarios that require high-precision speed regulation, such as production line motor drive and robot joint control.

Power system optimization: DC-AC power conversion is achieved through inverters to improve energy utilization efficiency.

Equipment upgrade and maintenance: As a key spare part of ABB transmission systems, it is used for performance upgrades or fault replacement of old equipment.
