TMCM-1140 TMCL Firmware V1.19 Manual (Rev. 1.01 / 2012-JUL-27) 4 1 Features The TMCM-1140 is a single axis controller/driver module for 2-phase bipolar stepper motors with state of the art feature set. It is highly integrated, offers a convenient handling and can be used in many decentralized applications. The module can be mounted on the back of NEMA 17 (42mm flange size) stepper motors and has been designed for coil currents up to 2 A RMS and 24 V DC supply voltage.
TMCM-1140 TMCL Firmware V1.19 Manual (Rev. 1.01 / 2012-JUL-27) 5 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.

TMCM-1140 TMCL Firmware V1.19 Manual (Rev. 1.01 / 2012-JUL-27) 19 In the example above, the interrupt numbers are used directly. To make the program better readable use the provided include file Interrupts.inc. This file defines symbolic constants for all interrupt numbers which can be used in all interrupt commands. The beginning of the program above then looks like the following: #include Interrupts.
TMCM-1140 TMCL Firmware V1.19 Manual (Rev. 1.01 / 2012-JUL-27) 20 3.5 The ASCII Interface There is also an ASCII interface that can be used to communicate with the module and to send some commands as text strings. THE FOLLOWING COMMANDS CAN BE USED IN ASCII MODE: ROL, ROR, MST, MVP, SAP, GAP, STAP, RSAP, SGP, GGP, STGP, RSGP, RFS, SIO, GIO, SCO, GCO, CCO, UF0, UF1, UF2, UF3, UF4, UF5, UF6, and UF7.

The value parameter must then be set to a value between 0… 255, where every bit represents one output line. Furthermore, the value can also be set to -1. In this special case, the contents of the lower 8 bits of the accumulator are copied to the output pins. Example: Set all output pins high.

TMCM-1140 TMCL Firmware V1.19 Manual (Rev. 1.01 / 2012-JUL-27) 61 3.6.38 TMCL Control Functions The following functions are for host control purposes only and are not allowed for standalone mode. In most cases, there is no need for the customer to use one of those functions (except command 139). TMCL control commands have no mnemonics, as they cannot be used in TMCL programs. These Functions are to be used only by the TMCL-IDE (e.g. to download a TMCL application into the module).
TMCM-1140 TMCL Firmware V1.19 Manual (Rev. 1.01 / 2012-JUL-27) 62 SPECIAL REPLY FORMAT OF COMMAND 136: Type set to 0 - reply as a string: Byte index 1 2… 9 - Contents Host Address Version string (8 characters, e.g. 1140V1.17) There is no checksum in this reply format! To get also the last byte when using the CAN bus interface, just send this command in an eight byte frame instead of a seven byte frame. Then, eight bytes will be sent back, so you will get all characters of the version string.

TMCM-1140 TMCL Firmware V1.19 Manual (Rev. 1.01 / 2012-JUL-27) 70 4.1 stallGuard2 The module is equipped with TMC262 motor driver chip. The TMC262 features load measurement that can be used for stall detection. stallGuard2 delivers a sensorless load measurement of the motor as well as a stall detection signal. The measured value changes linear with the load on the motor in a wide range of load, velocity and current settings. At maximum motor load the stallGuard2 value goes to zero.

Together with user definable commands these variables form the interface between extensions of the firmware (written in C) and TMCL applications. 5.3 Bank 2 Bank 2 contains general purpose 32 bit variables for the use in TMCL applications.
TMCM-1140 TMCL Firmware V1.19 Manual (Rev. 1.01 / 2012-JUL-27) 75 5.4 Bank 3 Bank 3 contains interrupt parameters. Some interrupts need configuration (e.g. the timer interval of a timer interrupt). This can be done using the SGP commands with parameter bank 3 (SGP , 3, ). The parameter number defines the priority of an interrupt. Interrupts with a lower number have a higher priority.

TMCM-1140 TMCL Firmware V1.19 Manual (Rev. 1.01 / 2012-JUL-27) 79 6.2 Changing the Prescaler Value of an Encoder The TMCM-1140 module offers the integrated sensOstep encoder. The built-in encoder has 1024 steps/rotation. Note: This hint about selecting a prescaler value is valid for the internal sensOstep encoder and for external encoders, if their resolution is 1024 steps/rotation. For different encoder resolutions new values have to be identified.
TMCM-1140 TMCL Firmware V1.19 Manual (Rev. 1.01 / 2012-JUL-27) 80 6.3 Using the RS485 Interface With most RS485 converters that can be attached to the COM port of a PC the data direction is controlled by the RTS pin of the COM port. Please note that this will only work with Windows 2000, Windows XP or Windows NT4, not with Windows 95, Windows 98 or Windows ME (due to a bug in these operating systems). Another problem is that Windows 2000/XP/NT4 switches the direction back to receive too late.
TMCM-1140 TMCL Firmware V1.19 Manual (Rev. 1.01 / 2012-JUL-27) 81 7 TMCL Programming Techniques and Structure 7.1 Initialization The first task in a TMCL program (like in other programs also) is to initialize all parameters where different values than the default values are necessary. For this purpose, SAP and SGP commands are used. 7.2 Main Loop Embedded systems normally use a main loop that runs infinitely. This is also the case in a TMCL application that is running stand alone.
TMCM-1140 TMCL Firmware V1.19 Manual (Rev. 1.01 / 2012-JUL-27) 82 Just have a look at the file TMCLParam.tmc provided with the TMCL-IDE. It contains symbolic constants that define all important parameter numbers. Using constants for other values makes it easier to change them when they are used more than once in a program. You can change the definition of the constant and do not have to change all occurrences of it in your program. 7.
TMCM-1140 TMCL Firmware V1.19 Manual (Rev. 1.01 / 2012-JUL-27) 83 7.6 Mixing Direct Mode and Standalone Mode Direct mode and standalone mode can also be mixed. When a TMCL program is being executed in standalone mode, direct mode commands are also processed (and they do not disturb the flow of the program running in standalone mode). So, it is also possible to query e.g. the actual position of the motor in direct mode while a TMCL program is running.
