Operand Example Description
MISC
PF 0 - 3 #ACD1
Sets Mixed
Mode damping
to 15% Percent Fast Decay - Command or Query
Default = 2
- Allows the Damping Mode of the driver IC to be set.
0 = Fast Decay
1 = Mixed Mode 15%
2 = Mixed Mode 48%
3 = 100%
The optimum setting will vary with motor inductance and step
rate; however the default ‘Mixed Mode’ setting will work well with
almost all motors.

(‘X’) My Address - Command or Query
Default = 65

RS - #ARS
Reads the
switch inputs Read Switches - Query Only
- Reads the TRUE (1) or FALSE (0) state of the three optically
coupled inputs, combined into a single three-bit value. This
command is used to check the correct operation of this interface.
- The value order of the inputs is ‘Direction’, ‘Disable’, and ‘Step’;
in descending order.
‘Direction’ has the value 4 (100)
‘Disable’ has the value 2 (010)
‘Step’ has the value 1 (001)
TI - #ATI
Reads the
switch inputs Test Inputs - Query only
Step, Direction, and Disable all return a value in decimal form.
The value order of the inputs is:
‘Direction’, ‘Disable’, and ‘Step’; in descending order.
‘Direction’ has the value 4 (100)
‘Disable’ has the value 2 (010)
‘Step’ has the value 1 (001)
