8.3.10 0x14 – Read driver mode
First Master writes 0x14 command (no data bytes are needed). In a next step Master reads one byte
of data. Read value represents driver mode:
Mode value

1
Default mode – external control
2
Step control
3
DC motor control
4
Position control
5
BINx buttons
6
Auto run mode
8.3.11 0x20 – Read full scale current
To read PoStep full scale current first Master writes 0x20 command (no data bytes are needed). In a
next step Master reads two bytes of data. Calculated current is:
current/A = 0.065*BYTE0 / (2
BYTE1
)
8.3.12 0x21 – Read idle current
First Master writes 0x21 command (no data bytes are needed). In a next step Master reads two bytes
of data. Same formula applies as in subsection 8.3.11 0x20 – Read full scale current to calculate idle
current value.
8.3.13 0x22 – Read overheat current
First Master writes 0x22 command (no data bytes are needed). In a next step Master reads two bytes
of data. Same formula applies as in subsection 8.3.11 0x20 – Read full scale current to calculate
overheat current.
8.3.14 0x23 – Read step mode
First Master writes 0x23 command (no data bytes are needed). In a next step Master reads one byte
of data. Read value represents step mode:
Mode value = BYTE0 & 0x0F

NOTE!
Driver mode is read only value for I2C communication and can only be set by using
USB connection and PoStep60 application!
