ABB DCS 600 MultiDrive ABB DCS 600 MultiDrive Thyristor Power Converters Series

Electrical Specifications

Power supply parameters: The power supply of the electronic equipment has various specifications such as 115V/230V, 

which need to be matched with the corresponding transformer; 

the rated voltage of the armature circuit converter power supply and the excitation power supply unit need to satisfy the specific conditions, 

or else measures need to be taken. 

There is no special phase sequence requirement for the main power supply connection,

but an isolation transformer should be installed when using oscilloscopes to achieve potential isolation and avoid ground loops.

Motor-related parameters: 

The motor voltage and the excitation voltage are calculated differently for different models of DCS 600. 

For example, for the DCS 601, the maximum motor voltage U Amax = line voltage * 1.16 (2 - quadrant unit);

 the excitation voltage is calculated according to different standards for different excitation power supply units. 

In addition, parameters such as rated motor current and rated motor field current are involved for the relevant control and monitoring.

Control specifications

Control functions: Various control functions are available, e.g. the emergency stop function is set via binary input DI5 

and different stop modes and ramp times can be selected. 

The software is divided into two parts, SDCS - CON - 2 and SDCS - AMC - DC. 

The internal signal connections for data transfer via automatic and programmable channels cover the transfer of a wide range of parameters and the realisation

of functions.

Parameter setting: Numerous parameters are used to set and adjust the operating status  of the device, such as setting the rated value parameters (rated line voltage, rated power converter current, etc.), 

control mode parameters (selection of modes such as speed control, torque control, etc.), 

and controller parameters (parameter adjustment of current controllers, speed controllers, EMF controllers, etc.).

Communication specifications

Communication interface and protocol: 

When communicating with a variety of devices, there are requirements for hardware connection and software settings. 

For example, to communicate with APC, YPQ112B board is used, cable length is 0.2-20m,

 plastic optical fibre, and specific parameters are set by software; to communicate with Profibus, NPBA02 board is used, 

and corresponding parameters need to be set by software, and attention should be paid to the data updating and consistency checking before communication.

Communication Parameters: The parameter settings are different in different communication modes, 

such as module type, mode, driver number, bit rate and other parameters for Profibus communication; 

Modbus PLUS communication requires setting module type, mode, driver number and various data-related parameters.

Other specifications

Safety related: There is an emergency stop button, and the operation should follow the relevant safety regulations. 

Electrostatic discharge may damage the equipment, should take appropriate protective measures.

Environmental conditions: equipment storage and transport to meet certain environmental conditions,

 operation of the environment temperature, humidity, altitude and other requirements to ensure the normal operation of the equipment .

Technical characteristics

Diversified control functions: support a variety of control modes, such as speed control, 

torque control and excitation mode, which can meet the needs of different industrial applications. 

With automatic adjustment function, such as current controller and excitation current controller can be automatically tuned, 

which can adapt to different motor and load characteristics and optimise the control performance. 

The control mode and characteristics can be flexibly adjusted by setting different parameters, such as setting the speed feedback mode (analogue tacho, encoder or EMF signal), adjusting the controller parameters (KPS, TIS, etc.) to optimize the control response.

Strong communication capability: it can communicate with various devices, such as APC, AC 70, AC 80, FCI, Profibus, Modbus PLUS, CS 31, etc., adapting to different industrial automation system architectures. Adopting plastic optical fibre and other communication media, the transmission speed is fast, for example, the transmission speed can reach 4Mb when communicating with AC 70, AC 80 and so on. Flexible communication settings, different devices need to set the corresponding parameters for communication, such as node type, driver number, communication protocol-related parameters, etc., to ensure stable communication.

Perfect protection mechanism: It is equipped with various fault detection and protection functions, 

which can detect over-current, over-voltage, under-voltage, over-speed, ground fault, motor overload, 

overheating and other faults, and send out signals in time to take corresponding protection measures, 

such as cutting off circuits, alarms, etc., to protect the safety of equipments and personnel.
