zero will enable the second current range. Setting the max.
motor current scaling factor to 232 (TMCL command SAP 6,
0, 232) will then increase motor driver output current to
2A RMS during movements. Please note: changing motor
current will happen immediately
–
therefore it is
recommended to first set the current scaling value (SAP 6,
0, 232 resp. SAP 7, 0, 232) and then switch the range (SAP
179, 0, 0). Settings above 232 up-to 255 are not
recommended as they might violate component
specifications.

RS485 transceiver: the RS485 transceiver has been replaced
with the SN65HVD1781 transceiver offering better fault
protection (up-to 70V fault protection) and supporting
higher communication speeds (up-to 1Mbit/s).
General purpose outputs OUT0 / OUT1: the driver circuit of
the open-drain output MOSFETs has been modified in
order to ensure glitch-free power-up. That is, output
MOSFETs will not turn briefly on while processor still in
reset / processor outputs not initialized.
-
External S/D input. The circuit for the external STEP / DIR
input has been optimized for higher step frequencies. Step
frequencies above 1MHz are supported under optimum
conditions.

*): V10, V11: prototypes only.
**) V12: series product version. Is replaced with V13 series product version due to EOL (end-of-life) of the driver
MOSFETs. Please see “PCN_1013_12_27_TMCM-1141.pdf” on our Web-site, also
