SR41 controller Details
Recording Menu: This menu displays the servo positions and records steps, if no steps are recorded when entering this menu then the previously recorded steps remain loaded and unchanged
Step Rate Menu: This menu displays the desired time between steps. Pressing the left switch increases the value. Values are changeable in increments of 20ms, with a maximum of 2seconds per step and a minimum of 20ms per step.
Max Servo Speed Menu: This menu displays the maximum servo speed. Pressing the left switch increases the value. Values are changeable from 1 to 10. Units are approximately 90degrees/second for a standard servo.
Repeat Menu: This menu displays the number of times to repeat the recorded steps. Pressing the left switch increases the value. Accepted values are 1 to 1000 and infinite.
Playback Menu: This menu displays the progress of a running servo. Pressing the left switch exits this menu and pressing the right switch starts, pauses and continues the progress. Visible data is the step number, the repeat count number and the voltage and current fed to the servo. The current is actually in units of 40mA per unit not 1 Amp per unit, 11A is 440mA. The voltage is in units of 10mV per unit, 502V is 5.020V not five hundred and one volts.
