TMCM-6212 TMCL™ Firmware Manual • Firmware Version V1.11 | Document Revision V1.07 • 2019-JAN-25 6.1.1 123 / 140 Mode 1 Reference search mode 1 only searches the left end switch. Select this mode by setting axis parameter #193 to 1. Figure 4 illustrates this. Add 64 to the mode number (i.e. set axis parameter #193 to 65) to search the right end switch instead of the left end switch.

Please note that the TMCM-6212 is an open-loop system, and hence encoders can only be used to check if the motor has really reached its target position or really follows the position counter.

Please bear in mind that the ﬁgure only shows one example for a drive. There are parameters which concern the conﬁguration of the current. Other parameters are there for velocity regulation and for time adjustment. Figure 12 shows all the adjustment points for CoolStep.

TMCM-6212 TMCL™ Firmware Manual • Firmware Version V1.11 | Document Revision V1.07 • 2019-JAN-25 CoolStep Adjustment Points and Thresholds Number Axis Parameter Description I6 Absolute maximum current The maximum value is 255. This value means 100% of the maximum current of the module. The current adjustment is within the range 0. . . 255 and can be adjusted in 32 steps (0. . . 255 divided by eight; e.g. step 0 = 0. . . 7, step 1 = 8. . . 15 and so on).

Acceleration and deceleration units are given in pps2 . When axis parameter #255 is set to 0 the internal units of the ramp generators are directly used.

TMCM-6212 TMCL™ Firmware Manual • Firmware Version V1.11 | Document Revision V1.07 • 2019-JAN-25 7 132 / 140 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.

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-6212 TMCL™ Firmware Manual • Firmware Version V1.11 | Document Revision V1.07 • 2019-JAN-25 7.5 134 / 140 Using Subroutines The CSUB and RSUB commands provide a mechanism for using subroutines. The CSUB command branches to the given label. When an RSUB command is executed the control goes back to the command that follows the CSUB command that called the subroutine. This mechanism can also be nested. From a subroutine called by a CSUB command other subroutines can be called.

They can be called from a host by issuing a run command with address 0 to call the ﬁrst function, or a run command with address 1 to call the second function, or a run command with address 2 to call the third function.
