ABB DSTA 002A 3BSE015196R1 Connection Unit

Bipolar chopper drive - patented 4-phase PWM (pulse width modulation) chopping electronically controls the motor winding currents at 20 KHz frequency. This combines the best of recirculating and non-recirculating current regulation producing high back EMF rejection with low chopping ripple current. Benefits include: reduced heat dissipation, low electric noise and improved current control during motor braking. Internal power supply - AC off line operation is dip switch selectable for either 120 or 240 Vac input. The main motor supply consists of a PWM switching supply. Shunt regulator circuitry -protects the drive by disabling the drive if the DC bus voltage exceeds 84 volts (at external connector J6). This feature protects the circuitry from excessive voltage that may be generated under certain motor deceleration conditions. Short circuit protection circuitry - disables the drive if a short circuit occurs on the motor outputs. The drive must be power cycled to clear fault.

Power supply features 

66 Vdc output - three pin pluggable connector (J6) provided to supply 66 Vdc to power an additional drive. The total power available for both the internal and external drives is 66 Vdc @ 4.6 Amps or 300W ±10%. Indexer features The indexer circuitry provides programmable motion control and allows flexible interfacing to the application. Pacific Scientific StepperBASIC - programming language with over 100 instructions, combines the ease of the programming language BASIC with sophisticated motion control features. Serial port RS-232 or RS-422/485 communications -interfacing the user computer or terminal for programming and/or computer control. RS-422/485 control allows multiple 6445 units to be controlled from a single computer or terminal

Indexer features (cont’d)

 12 outputs - user programmable outputs to external devices. One output is program-selectable to indicate motor moving. 16 inputs - user programmable inputs from external devices. Six inputs can be pre-defined for limit, start, stop, and jog functions. Encoder inputs - for position verification, or for electronic gearing. Alternatively, these inputs can be redefined for external step and direction control. Step and direction outputs - outputs step and direction signals for control of another drive. Memory - indexer memory capacity is 12K bytes (battery-backed RAM).
