Parameterizing the actual value resolution depending on the axis type (linear/rotary axis)The control system calculates the actual value resolution based on the following machine data.Machine data for calculating the actual value resolution Linear axis Linear axis Rotary axisLinear scale /direct measuringsystemIndirectmeasur‐ing systemDirectmeasuringsystem:Machine/toolIndirectmeasur‐ing sys‐temDirectmeasur‐ing sys‐tem: Ma‐chine/toolMD30300 $MA_IS_ROT_AX 0 0 0 1 1MD31000 $MA_ENC_IS_LINEAR[ n ]MD31010 $MA_ENC_GRID_POINT_DIST[ n ]MD34320 $MA_ENC_INVERS[ n ]1Spacing1)0--0--0--0--MD31020 $MA_ENC_RESOL[ n ] - Pulses/revPulses/revPulses/revPulses/revMD31025 $MA_ENC_PULSE_MULT[ n ] Encoder multipli‐cationMD31030 $MA_LEADSCREW_PITCH - mm/rev. mm/rev. - -MD31040 $MA_ENC_IS_DIRECT[ n ] - / 1 0 1 0 1MD31044 $MA_ENC_IS_DIRECT2[ n ] - / 1 0 1 0 1MD31050 $MA_DRIVE_AX_RATIO_DENOM[ n ] - Loadrev.- / 1 Loadrev.2)MD31060 $MA_DRIVE_AX_RATIO_NUMERA[ n ] - Motorrev. if in‐feedgear avail‐able- / 1 Motorrev.2)MD31070 $MA_DRIVE_ENC_RATIO_DENOM[ n ] - Encoderrev.Encoderrev.Encoderrev.Encoderrev.MD31080 $MA_DRIVE_ENC_RATIO_NUMERA[ n ] - Motor-side en‐coder 3)Motorrev.Motorrev.Loadrev.- Not relevant1) For distance-coded measuring systems2) These machine data are not required for encoder matching (path evaluation). However,they must be entered correctly for the setpoint calculation! Otherwise the required servogain factor (KV) will not be set. The load revolutions are entered into machine dataMD31050 $MA_DRIVE_AX_RATIO_DENOM and the motor revolutions in machine dataMD31060 $MA_DRIVE_AX_RATIO_NUMERA.3) The encoder on the motor side is a built-in encoder and, therefore, does not have ameasuring gear unit.The transmission ratio is always 1:1.G2: Velocities, setpoint / actual value systems, closed-loop control7.4 Setpoint/actual-value systemBasic FunctionsFunction Manual, 01/2015, 6FC5397-0BP40-5BA2 349
