The following procedure is used to access the independently programmable "Hold" and "Run" current feature:
1.Issue the "Y" command to program the desired current values. Entering Y10 80 yields a 10% Hold current and 80% Run current.
2.Issue an "S" (Save) command. The values are now stored in
On receipt of an index or other motion command, the control circuits are incremented to the 80% boost, while moving is in process. On completion of motion (and settling time delay) the current is automatically reduced to the 10% Hold current level.
Quiet Mode
To access the "Current Disable" feature use the following current setup procedure:
Enter | Result |
Y00 80 | Initiates current program mode, sets Hold current at 0% and Run current at 80% of |
| maximum. The |
Note: Refer to “About Step Motor Current” in the Addendum for more detail on setting the proper motor current.

During motor move commands the value will change depending on the direction of travel. The counter is programmable by the “O” command.
The
The readout mode will be defaulted as “On” if a SAVE command is issued. This mode is only practical using single axis protocol.
The controller is factory set with the following program example:
P 0 | Enter program mode. |
+1001 Move 1001 steps in the plus direction.
W 100 Wait 100 milliseconds.
- 1000 Move 1000 steps in the minus direction.
W 100 Wait 100 milliseconds.
Z 0 | Display step position. |
G 0 0 | Go to location 0 and run stored program. |
P | Exit program mode. |
