60mm stepper motor with integrated controller/driver has on-the-fly alteration of motion parameters

The chopSync™ feature allows high-speed movement without mid-range resonance problems, and the internal sensOstep™ encoder can be used to detect step loss or to control the target position. In addition there is an input for an optional external incremental encoder.

The power supply, interface and the multi purpose I/Os can be connected with small D-SUB connectors and comes with the PC based software development environment TMCL-IDE for the Trinamic Motion Control Language (TMCL™). Using predefined high level commands like ‘move to position’ or ‘constant rotation’ a rapid and fast development of motion control applications is guaranteed. Communication traffic is kept very low since all time critical operations e.g. ramp calculation are performed on board. It can be host controlled by serial interface. The TMCL™ program can be stored in the on board EEPROM for stand-alone operation and the firmware of the module can be updated via the serial interface. With the 'CANopen' firmware option it is possible to operate the module in CANopen networks together with other equipment.

The interfaces employed are CAN, RS-232 and RS-485 host interface. There are 2 stop switch inputs, 1 homing/reference input (5V & 24V compatible) and 2 general-purpose inputs (24V compatible) as well as incremental encoder (ABN).

The motor used has a 60mm/NEMA24 flange size, shaft diameter 8mm with D-cut, shaft length 25mm and current 2.8amps.

The main features of the PD-146-60-SE are:

• up to 1024 times microstepping
• memory for 2048 TMCL™ commands
• automatic S-shaped or trapezoidal acceleration ramp generation in hardware
• easyPID™ controller for position maintenance (using external encoder)
• on the fly alteration of motion parameters (e.g. position, velocity, acceleration)
• dynamic current control
• chopSync™ feature for higher motor speed by reducing mid-range resonance
• integrated absolute sensOstep™ encoder (max. 4096 cpr)
