To allow the motor to drive near the reference point, it is possible to exclude a motion range of steps from the stop switch function. The parameter DX_REF_TOLERANCE disables automatic stopping by a switch around the origin (see Figure 6.4). To use the DX_REF_TOLERANCE far from the origin, the actual position has to be adapted, e.g. by setting it to zero in the center of the tolerance range. Additionally, the parameter DX_REF_TOLERANCE affects interrupt conditions as described before (section 6.1.11). 6.1.14 X_LATCHED (IDX=%1110) This read-only register stores the actual position X_ACTUAL upon a change of the reference switch state. The reference switch is defined by the bit ref_RnL of the configuration register 6.2.1.5. Writing a dummy value to the (read-only) register X_LATCHED initializes the position storage mechanism. The actual position is saved with the next rising edge or falling edge signal of the reference switch depending on the actual motion direction of the stepper motor. The actual position is latched when the switch defined as the reference switch by the ref_RnL bit changes (see chapter 1.5.4). The status bit lp signals, if latching of a position is pending. This way, a precise reference is available for homing. An event at the reference switch associated to the actual motion direction takes effect only during motion (when V_ACTUAL 0). |
