Description
SETTING CURRENT
HI 0-3000
#AHI300 
 
Sets the Hold 
Current to 
300mA (0.3A) 
Hold Current - Command or Query - 0 to 3000 
Default = 300 
- Reads or sets the motor Holding Current in 100 milliamps 
increments. The value does not round. 
RI 300 - 3000
#ARI1000 
 
Sets the run 
current to 1000 
mA (1.0 Amp) 
Run Current - Command or Query 
Default = 1000 
- Sets the motor Phase Current for any form of motion in 
milliamps. 
300 = 300mA (0.3 Amp) 
2500 = 2500mA (2.5 Amp) 
The last two numbers of the value are not read. 
350 = 300mA, 2499 = 2400mA 
- The set ‘Run Current’ is maintained for a time set by ‘Hold 
Timeout’ (HT) before dropping to the current set by ‘Hold 
Current’ (HI) 
 
NOTE: Current of 2.7 Amp and above REQUIRES an 
additional heatsink, make sure the temperature of the 
bracket does not exceed 45° C
HT 100 -5000
#AHT100 
 
Sets the Hold 
Timeout to 100 
mS 
Hold Timeout - Command or Query 
Default = 5000 
- Reads or sets the time interval in milliseconds after any motor 
movement, before the motor current is changed from Run 
Current to Hold Current. 
 
STORAGE & RECALL
LD -
#ALD 
 
Loads all the 
default values 
Load Defaults - Command Only 
- Loads all of the unit Default parameter values. A Save Data 
(SD) command must be issued to have these values retained 
during a power cycle. 
 
Default values are: 
Module Address 65 (A) 
Acceleration 50 
Absolute Position 0 
Percent Fast Decay 2 
Hold Current 300 (0.3A) 
Hold Timeout 5000 
Minimum Velocity 256 
Run Current 1000 (1.0A) 
Step Resolution 16 
Start Velocity 1000 
Velocity Limit 15000 
SD -
#ASD 
 
Saves data 
Save Data - Command Only  
- This command causes a set of parameter values to be 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
