Quick Start

Setting the Current

There are two current settings on the R101.

  1. Run Current (RI) – The peak current that the motor will be run at while in motion.
  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 2.0A:
#ARI20

To set Hold Current to 0.3A:
#AHI3

Setting Step Resolution

The R101 is capable of full stepping or 2, 4, and 8x microstepping.

Example:
To set Step Resolution to 4x microstepping:
#ASR4

Saving the Configuration

In order to have these settings retained upon a power cycle, the data must be saved.
The command to store these settings is “SD” (Save Data).

Example:
To save settings:
#ASD

Connecting the Motor

CAUTION! Make sure the power is OFF when connecting or disconnecting motors.

Please refer to your motor documentation for wiring color code.
Connect the corresponding Phase from the motor to the proper pin on the R101.

What next?

If using the R101 in Step/Direction mode, please proceed to Section 8 – Basic Step and Direction Operation.

If using the R101 as a simple controller, please see the Command Tables in Section 9 and more detailed descriptions of the Commands in Section 10.
