Application information
For driving a stepper motor we suggest to use the following codes. The columned ’SDO
correct’ shows the data returned at SDO in correct function. The columns presented under
’Error cases’ display the diagnosis bits if errors are detected.
Examples of control sequences.
These sequences are intended to give the user a good starting point for his software
development. Besides these two there are further possibilities how to implement control
sequences for this device (other currents, quarters step etc.).
Double errors: Double errors will create composite codes by an AND operation between
columns of the same dominance. Open and short to VS are the least dominant error codes.
(first 6 error code columns). Short to ground is the second dominant error code. detection of
short to gnd will overwrite error codes of the least dominant kind (open, short to VS).
Temperature pre alarm and thermal shut down are the most dominant error codes. Thermal
pre alarm returns error code 00 but the device still is working and returns the appropriate
operation code (bits 0..5).
Thermal shut down returns error code 00 and turns off the device. The opcode returned
corresponds the action eventually performed (bit 0..5 become 1).
For example open bridge A and simultaneously open bridge B will lead to error code 01 by
performing an AND operation between the two corresponding columns.

1.
Motor resistance approximately 10
Ω and V
S = 12V. So a short to ground only is detected on one branch of the bridge.
Lower resistivity of the motor may lead to detection of short to ground on both branches of the bridge leading to code 10 on
all steps.
