TRINAMICS UNIQUE FEATURES – EASY TO USE WITH TMCL

stallGuard2™ stallGuard2 is a high-precision sensorless load measurement using the back EMF on the

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 goes to zero or
near to zero. This is the most energy-efficient point of operation for the motor.

Figure 1.1 stallGuard2 load measurement SG as a function of load

coolStep™ coolStep is a load-adaptive automatic current scaling based on the load measurement via

stallGuard2 adapting 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 reducing cost.

3 Mechanical and Electrical Interfacing

The PD-1021 consists of a 28mm / NEMA 11 stepper motor with controller/driver electronics mounted to
the back of the motor.

Note:
In order to make proper use of the integrated sensOstep encoder (the sensor IC is placed on the bottom
of the pcb) the electronics should not be removed/moved relative to the motor. In case this encoder
feature is not used, the electronics may be mounted according to different application requirements.

3.1 Dimensions

Currently, there is a choice between two 28mm stepper motors of different lengths and different torques.
The board with the controller/driver electronics has an overall size of 28mm x 28mm in order to fit on
the back side of a NEMA11 (28mm flange size) stepper motor. The printed circuit board outline is marked
green in the following figure.

Please also refer to the manuals of the related stepper motors QSH2818-32-07-006 and QSH2818-51-07-

012.

PD-1021 Hardware Manual (Rev. 1.00 / 2012-JUN-20) 11

3.4 Power Supply

For proper operation care has to be taken with regard to power supply concept and design. Due to space
restrictions the PD-1021 includes just about 20µF/35V of supply filter capacitors. These are ceramic
capacitors which have been selected for high reliability and long life time. The module includes a 28V
suppressor diode for over-voltage protection. There is no reverse polarity protection. The module will
short any reversed supply voltage due to internal diodes of the driver transistors.

It is absolutely necessary that the power supply voltage is kept below the upper limit of 28V under all
circumstances (please see also chapter 6, operating values). Otherwise the driver electronics might be
seriously damaged! Especially, when the selected operating voltage is near the upper limit a regulated
power supply is highly recommended.

It is recommended to connect an electrolytic capacitor of significant size (e.g. 470µF/35V) to the power
supply lines next to the PD-1021!

Rule of thumb for size of electrolytic capacitor:   

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 ceramic-only filter capacitors may cause stability problems with some switching power supplies.

3.5 Communication

3.5.1 RS485

For remote control and communication with a host system the PD-1021 provides a two wire RS485 bus
interface. For proper operation the following items should be taken into account when setting up an
RS485 network:

1. 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 3.5 Bus structure

2. 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 PD-1021 does
not integrate any termination resistor. Therefore, 120 Ohm termination resistors at both ends of
the bus have to be added externally.

3. NUMBER OF NODES:

The RS485 electrical interface standard (EIA-485) allows up to 32 nodes to be connected to a
single bus. The bus transceiver used on the PD-1021 units (SN65HVD3082ED) has just 1/8th of the
standard bus load and allows a maximum of 256 units to be connected to a single RS485 bus.

4. NO FLOATING BUS LINES:

Avoid floating bus lines while neither the host/master nor one of the slaves along the bus line is
transmitting data (all bus nodes switched to receive mode). Floating bus lines may lead to
communication errors. In order to ensure valid signals on the bus it is recommended to use a
resistor network connecting both bus lines to well defined logic levels. In contrast to the
termination resistors this network is normally required just once per bus. Certain RS485 interface
converters available for PCs already include these additional resistors (e.g. USB-2-485).

3.6 Inputs and Outputs

3.6.1 Digital Inputs IN_0, IN_1, IN_2, IN_3

The eight pin connector of the PD-1021 provides four general purpose inputs IN_0, IN_1, IN_2 and IN_3.
The first two inputs have dedicated connector pins while the other two share pins with two general
purpose outputs.

All four inputs are protected using voltage resistor dividers together with limiting diodes against
voltages below 0V (GND) and above +3.3V DC (see figure below).

Figure 3.7: General purpose inputs

The four inputs have alternate functionality depending on configuration in software. The following
functions are available:

Table 3.5: Multi-purpose inputs / alternate functions

All four inputs are connected to the on-board processor and can be used as general purpose digital
inputs.

Using the alternate functionality of IN_0 and IN_1 it is possible to control the on-board stepper motor
driver with the help of an external stepper motor controller using step and direction signals. For the step
and direction signals the signal levels are the same as for the general purpose digital inputs.

IN_3 can be used as analog input, also. A 12bit analog to digital converter integrated in the
microcontroller will convert any analog input voltage between 0 and +6.6V to a digital value between 0
and 4095 then.

3.6.2 Outputs OUT_0, OUT_1

The eight pin connector of the PD-1021 provides two general purpose outputs. These two outputs are
open-drain outputs and can sink up to 100mA each. The outputs of the N-channel MOSFET transistors are
connected to freewheeling diodes each for protection against voltage spikes especially from inductive
loads (relais etc.).

Both outputs OUT_0 and OUT_1 share pins with two of the four inputs (IN_2 resp. IN_3).

Please take into account the 20k (2x 10k in series) resistance to ground (transistor not active) of the input
voltage divider (figure 4.8) when designing the external “load” circuit.

4 Reset to Factory Defaults

It is possible to reset the PD-1021 to factory default settings without establishing a communication link.
This might be helpful in case communication parameters of the preferred interface have been set to
unknown values or got accidentally lost.

For this procedure two pads on the bottom side of the board have to be shortened (see Figure 4.1).

Please perform the following steps:

1. Power supply off

2. Short two pads as marked in Figure 4.1

3. Power up board

4. Wait until the on-board green LED start flashing fast (this might take a while)

5. Power-off board (disconnect USB cable)

6. Remove short between pads

7. After switching on the power-supply all permanent settings have been restored to factory

defaults

Figure 4.1 Reset to factory default settings

5 On-board LED

The board offers one LED in order to indicate board status. The function of the LED is dependent on the
firmware version. With standard TMCL firmware the green LED flashes slowly during operation.

When there is no valid firmware programmed into the board or during firmware update the green LED is
permanently on.

8 Functional description

The PD-1021 is a highly integrated mechatronic device which can be controlled via RS485 serial interface.
Communication traffic is kept low since all time critical operations, e.g. ramp calculations are performed
on board. Nominal supply voltage of the unit is 24V DC. The PANdrive is designed for both: direct mode
and standalone operation. Full remote control of device with feedback is possible. The firmware of the
module can be updated via any of the serial interfaces.

Figure 8.1 the main parts of the PD-1021 are shown:

- the microprocessor, which runs the TMCL operating system (connected to TMCL memory),

- the motion controller, which calculates ramps and speed profiles internally by hardware,

- the power driver with stallGuard2 and its energy efficient coolStep feature,

- the MOSFET driver stage,

- the QSH stepper motor, and

- the sensOstep encoder with resolutions of 10bit (1024 steps) per revolution.

Figure 8.1: Main parts of PD-1021

The PD-1021 comes with 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 PD-1021 Firmware Manual for more information about TMCL commands.
