written to non-volatile memory. On power up the last set
of values written are set to be the parameter initial values.
-The parameters whose values are thus saved are:
My Address
Absolute Position
Velocity Limit
Minimum Velocity
Start Velocity
Acceleration
Hold Timeout
Step Resolution
Run Current
Hold Current
Percent Fast Decay

#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.
