TMCM-1021 TMCL Firmware V1.19 Manual (Rev. 1.04 / 2012-JUL-30) 1 Features The TMCM-1021 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 NEMA11 (28mm flange size) and has been designed for coil currents up to 0.7A RMS and 24V DC supply voltage.
TMCM-1021 TMCL Firmware V1.19 Manual (Rev. 1.04 / 2012-JUL-30) 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.

The current adjustment is within the range 0… 255 and can be adjusted in 32 steps (0… absolute max. current (CS / 255 divided by eight; e.g. step 0 = 0… 7, step 1 = 8… 15 and so Current Scale) on).
TMCM-1021 TMCL Firmware V1.19 Manual (Rev. 1.04 / 2012-JUL-30) 68 5 Global parameters Global parameters are grouped into 4 banks: bank bank bank bank 0 1 2 3 (global configuration of the module) (user C variables) (user TMCL variables) (interrupt configuration) Please use SGP and GGP commands to write and read global parameters. 5.1 Bank 0 Parameters with numbers from 64 on configure parameters like the serial address of the module RS485 baud rate.

TMCM-1021 TMCL Firmware V1.19 Manual (Rev. 1.04 / 2012-JUL-30) 70 5.3 Bank 2 Bank 2 contains general purpose 32 bit variables for the use in TMCL applications. They are located in RAM and the first 56 variables can be stored permanently in EEPROM, also. After booting, their values are automatically restored to the RAM. Up to 256 user variables are available.
TMCM-1021 TMCL Firmware V1.19 Manual (Rev. 1.04 / 2012-JUL-30) 71 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-1021 TMCL Firmware V1.19 Manual (Rev. 1.04 / 2012-JUL-30) 72 6 Hints and Tips This chapter gives some hints and tips on using the functionality of TMCL™, for example how to use and parameterize the built-in reference point search algorithm or the incremental sensOstep™ encoder. Further you will find basic information about stallGuard2™ and coolStep™. 6.1 Reference Search The built-in reference search features switching point calibration and support of one or two reference switches.

TMCM-1021 TMCL Firmware V1.19 Manual (Rev. 1.04 / 2012-JUL-30) 75 6.2 Changing the Prescaler Value of an Encoder The built-in encoder has 1024 steps per rotation. For the operation with encoder please consider the following hints: The encoder counter can be read by software and can be used to control the exact position of the motor. This also makes closed loop operation possible. To read out or to change the position value of the encoder, axis parameter #209 is used.
