11 Functional Description
The PD42-x-1240 is a full mechatronic solution including a 42mm flange (NEMA17) bipolar stepper motor.
It includes the controller / driver electronics TMCM-1240 and a choice between four different NEMA 17 /
42mm flange size bipolar hybrid stepper motors with different length and torque.
The PD42-x-1240 can be controlled via USB, RS485 or CAN serial interfaces. There are three general
purpose digital inputs which can be used, also as STOP_L / STOP_R / HOME switch inputs (for reference
movements, as end switches etc. depending on firmware, mode and configuration) or for connecting
an additional external encoder (incremental A/B/N). In addition, there is one dedicated analog input for
0. . . +10V analog signals and two general-purpose outputs (one open-drain and one switchable +5V supply
output).
The PD42-x-1240 with TMCL ™ firmware option is supported by the PC based software development
environment TMCL-IDE for the Trinamic Motion Control Language (TMCL ™ ). Using predefined TMCL ™
high level commands like move to position a rapid and fast development of motion control applications
is guaranteed. Please refer to the PD42-x-1240 or TMCM-1240 firmware manuals for more information
about TMCL™ commands.
Communication traffic is kept low since all time critical operations, e.g. ramp calculation are performed on
board. Complete stand-alone or full remote control or anything in-between is possible. The firmware of the
module can be updated via the serial interface. As an alternative to TMCL, a CANopen firmware is available.
The PD42-x-1240 contains the following main components:
• Microcontroller (ARM Cortex-M3™), responsible for overall control and communication
• Highly integrated advanced stepper motor controller supporting linear and unique 6-points ramps in
hardware
• Advanced stepper motor driver with StallGuard2 ™ and CoolStep ™ with MOSFET driver stage (8x
power N-MOSFETs for bipolar stepper motor)
• RS485, CAN and USB transceivers
• On-board voltage regulators (+5V and +3V3) required for supply of all on-board digital circuits
