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
