1 Feature s

The PANdrive™ PD28-1-1021 and PD28-3-1021 are small and compact full mechatronic solutions including NEMA11 / 28mm flange size stepper motors, the TMCM-1021 controller/ driver electronics and TRINAMIC sensOstep™ encoder for step-loss detection. The two PANdrives include stepper motor with different lengths and different holding torques (PD28-1-1021: 0.06Nm, PD28-3-1021: 0.12Nm) but, same electronics and encoder setup. The PANdrives support both, stand-alone operation e.g. using the on-board I/Os together with the build-in TMCL scripting feature and remote control operation using the RS485 2-wire communication bus interface and even a mixture of both.

MAIN CHARACTERISTICS

Highlights

Motion profile calculation in real-time

On the fly alteration of motor parameters (e.g. position, velocity, acceleration)

High performance microcontroller for overall system control and serial communication protocol handling

For position movement applications, where larger motors do not fit and higher torques are not required

Bipolar stepper motor driver

Up to 256 microsteps per full step

High-efficient operation, low power dissipation

Dynamic current control

Integrated protection

stallGuard2™ feature for stall detection

coolStep™ feature for reduced power consumption and heat dissipation

Encoder

sensOstep magnetic encoder (max. 1024 increments per rotation) e.g. for step-loss detection under all operating conditions and positioning supervision
