Features
The PANdrive™ PD42-1270 is a full mechatronic solution with state of the art feature set. It is highly integrated and offers convenient handling via CAN interface. The PD42-1270 includes a stepper motor, driver
electronics, and a fully featured hardware motion controller. It can be used in many decentralized applications and has been designed for 0.20...0.47 Nm maximum holding torque and 24V DC nominal supply
voltage. With StealthChop™, the PD42-1270 offers absolutely silent and smooth motor operation for lower

TRINAMIC’s Unique Features
stealthChop™
stealthChop is an extremely quiet mode of operation for low and medium velocities. It is based on a voltage mode PWM. During standstill and at low velocities, the motor is absolutely noiseless. Thus, stealthChop operated stepper motor applications are very suitable for indoor or home use. The motor operates
absolutely free of vibration at low velocities. With stealthChop, the motor current is applied by driving
a certain effective voltage into the coil, using a voltage mode PWM. There are no more configurations
required except for the regulation of the PWM voltage to yield the motor target current.
Figure 1: Motor coil sine wave current using stealthChop (measured with current probe)
1.2.2
spreadCycle™
The spreadCycle chopper is a high-precision, hysteresis-based, and simple to use chopper mode, which
automatically determines the optimum length for the fast-decay phase. Several parameters are available
to optimize the chopper to the application. spreadCycle offers optimal zero crossing performance compared to other current controlled chopper algorithms and thereby allows for highest smoothness. The
true target current is powered into the motor coils.
Figure 2: spreadCycle principle
1.2.3
stallGuard2
stallGuard2 is a high-precision sensorless load measurement using the back EMF of the motor coils. It
can be used for stall detection as well as other uses at loads below those which stall the motor. The

stallGuard2 measurement value changes linearly over a wide range of load, velocity, and current settings.
At maximum motor load, the value reaches zero or is near zero. This is the most energy-efficient point of
operation for the motor.

1.2.4
coolStep
coolStep is a load-adaptive automatic current scaling based on the load measurement via stallGuard2.
coolStep adapts the required current to the load. Energy consumption can be reduced by as much as
75%. coolStep allows substantial energy savings, especially for motors which see varying loads or operate
at a high duty cycle. Because a stepper motor application needs to work with a torque reserve of 30% to
50%, even a constant-load application allows significant energy savings because coolStep automatically
enables torque reserve when required. Reducing power consumption keeps the system cooler, increases
motor life, and allows for cost reduction.

Mechanical and Electrical Interfacing
PD42-1270 Dimensions
The PD42-1270 includes the TMCM-1270 stepper motor controller/driver module (electronics + encapsulating enclosure) and a NEMA17 / 42mm flange size bipolar stepper motor. Currently, there is a choice
between three NEMA17 / 42mm flange size stepper motors with different lengths and different holding
torques. All three stepper motors are rated for 1A RMS coil current - perfectly fitting to the TMCM-1270
electronics.
The dimensions of the controller/driver unit are approx. 42mm x 42mm x 12mm (TMCM-1270 electronics
+ encapsulating enclosure). There are two mounting holes for M3 screws for mounting on the back bell
of a NEMA17 / 42mm flange size stepper motor (screw/thread length depends on motor size).

NOTICE
Always keep the power supply voltage below the upper limit of 28V! Otherwise the driver electronics will be seriously damaged. Especially, when the selected operating voltage is near the upper limit a regulated power supply is highly
recommended.
NOTICE
Add external power supply capacitors! It is recommended to connect an electrolytic capacitor of significant size (e.g. 470µF/35V) to the power supply lines
next to the PD42-1270!
Rule of thumb for size of electrolytic capacitor: C = 1000µF
× ISU P P LY
A
In addition to power stabilization (buffer) and filtering this added capacitor will
also reduce any voltage spikes which might otherwise occur from a combination
of high inductance power supply wires and the ceramic capacitors. In addition it
will limit slew-rate of power supply voltage at the module. The low ESR of ceramiconly filter capacitors may cause stability problems with some switching power
supplies.
NOTICE
Tie ENN to GND in order to enable driver stage! Please note that pin 10 of the
Power supply and I/O connector is a hardware driver stage enable input (active
low) with an internal pull-up resistor. In order to enable motor driver stage and
be able to move the motor using appropriate software commands it is necessary
to tie this input to GND.
CAN Connection
For remote control and communication with a host system the PD42-1270 provides a CAN bus interface.
For proper operation the following items should be taken into account when setting up a CAN network:

Bus Structure The network topology should follow a bus structure as closely as possible. That is, the
connection between each node and the bus itself should be as short as possible. Basically, it should be
short compared to the length of the bus.
Figure 12: CAN bus strcuture
Bus Termination Especially for longer busses and/or multiple nodes connected to the bus and/or high
communication speeds, the bus should be properly terminated at both ends. The PD42-1270 does not
integrate any termination resistor. Therefore, 120 Ohm termination resistors at both ends of the bus
have to be added externally.
Number of Nodes The bus transceiver used on the PD42-1270 (TJA1051) supports at least 100 nodes
under optimum conditions. Practically achievable number of nodes per CAN bus highly depend on bus
length (longer bus → less nodes) and communication speed (higher speed → less nodes).
CAN Bus Adapters To quickly connect to the PD42-1270 a PC based intergated development environment TMCL-IDE is available. Latest release can be downloaded for free from our web site: www.trinamic.com
A number of common CAN interface adapters from different manufactures is supported from within this
software. Please make sure to check our web site from time to time for the latest version of the software!

Do not connect or disconnect motor during operation! Motor cable and motor inductivity might lead to voltage spikes when the motor is connected / disconnected while energized. These voltage spikes might exceed voltage limits of the
driver MOSFETs and might permanently damage them. Therefore, always switch
off or disconnect power supply before connecting or disconnecting the motor.
