1 Features
The PANdrive™ PD-1021 is a full mechatronic extremely small and compact solution with state of the art
feature set. It is highly integrated and offers a convenient handling. The PD-1021 includes a stepper
motor, controller/driver electronics, and TRINAMICs sensOstep™ encoder. It can be used in many
decentralized applications and has been designed for 0.06… 0.12 Nm max. holding torque and 24V DC
nominal supply voltage. With its high energy efficiency from TRINAMIC’s coolStep technology cost for
power consumption is kept down. The TMCL™ firmware allows for standalone operation and direct
mode.
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
- ready for dcStep
Encoder
- sensOstep magnetic encoder (max. 1024 increments per rotation) e.g. for step-loss detection under
all operating conditions and positioning supervision
Interfaces
- Up to 4 multi-purpose inputs (2 shared with outputs)
- 2 general purpose outputs
- RS485 2-wire communication interface
Software
- TMCL: standalone operation or remote controlled operation,
program memory (non volatile) for up to 876 TMCL commands, and
PC-based application development software TMCL-IDE available for free.
Electrical and mechanical data
