NoteMachine data index [ n ]The machine data index [ n ] for encoder assignment has the following meaning:● n = 0: First encoder assigned to the machine axis● n = 1: Second encoder assigned to the machine axisThe assignment is made using machine data:● MD30220 $MA_ENC_MODULE_NR[ n ]● MD30230 $MA_ENC_INPUT_NR[ n ]Further informationCommissioning Manual, CNC Commissioning: NC, PLC, drive; communication between NCand drive > Drives: Assign axis2.4.3 Adapting the motor/load ratiosGear typesThe following gear types are available for adapting the mechanical ratios:Gear type Activation Adaptation Installation locationMotor/load gear Parameter set Fixed configuration Gear unitMeasuring gear encoder Power On Sensor-dependent Sensor-sideLoad intermediate gear unit Warm restart Load-dependent Tool-sideLocal position of gear unit / encoder0RWRUORDGJHDUER[1RRIORDGUHY1RRIWRROUHY1RRIPRWRUUHY1RRIORDGUHY00RWRUHQFRGHU /RDGHQFRGHU 7RROHQFRGHU7RROV'5,9(B$;B5$7,2B180(5$'5,9(B$;B5$7,2B'(120'5,9(B$;B5$7,2B180(5$'5,9(B$;B5$7,2B'(120(1&B,6B',5(&7 (1&B,6B',5(&7 (1&B,6B',5(&7 (1&B,6B',5(&7 (1&B,6B',5(&7 (1&B,6B',5(&7 Figure 2-2 Gear unit types and encoder locationsG2: Velocities, setpoint / actual value systems, closed-loop control2.4 Setpoint/actual-value systemAxes and spindlesFunction Manual, 06/2019, A5E47437747B AA 55
