Setting the Current
There are two current settings on the R325I.
1. Run Current (RI) – The peak current that the motor will be run at while in
motion.
NOTE: Current of 2.7 Amp and above REQUIRES an additional heatsink, make sure the
temperature of the bracket does not exceed 45° C.
2. Hold Current (HI) – The current that the motor will receive when idle.
*The default board address of ‘A’ is used in all examples, please see “MA” command for more
detail on addresses.
Examples:
To set Run Current to 2000mA (2.0A):
#ARI2000
To set Hold Current to 300mA (0.3A):
#AHI300
Setting Step Resolution
The R325I is capable of full stepping or 2, 4, 8, 16, 32, 64, 128, and 256
microstepping.
