9 Motor driver current

The on-board stepper motor driver operates current controlled. The driver current may be programmed

in software with 32 effective scaling steps in hardware.

Explanation of different columns in table below:

Motor current set-

ting in software

(TMCL)

These are the values for TMCL axis parameter 6 (motor run current) and

7 (motor standby current). They are used to set the run / standby current

using the following TMCL commands:

SAP 6, 0, <value> // set run current
SAP 7, 0, <value> // set standby current

(read-out value with GAP instead of SAP. Please see separate TMCM-1260

ﬁrmware manual for further information)
