HEIDENHAIN MANUALPLUS 620 - 6.16.24 Motor with wye;delta switchover

936 HEIDENHAIN Technical Manual MANUALplus 620
6.16.24 Motor with wye/delta switchover
The parameter object CfgServoMotor is not required for:
 Virtual axes (MP_axisMode = Virtual)
 Axes that are for display only (MP_axisMode = Display)
 Analog axes (MP_axisMode =Analog)
Define different parameter sets if a wye/delta connection switchover is carried
out for an asynchronous motor. Use the Modules 9434 and 9435 to activate
the parameter set for operation with wye connection or operation with delta
connection (see "Switching Parameter Sets" on page 398).
For the two operating modes, you can use different machine parameters for
the current and speed controllers:
The switchover can be carried out during standstill or with a revolving spindle.
With Module 9173, a monitoring function dependent on the speed can be
realized for the wye/delta switchover of the spindle. You can interrogate the
current spindle status with reference to the wye/delta switchover with
Module 9174.
Performing a wye/delta connection switchover:
 Switch the drive controller off by using PP_AxDriveOnRequest.
 Use Module 9434 to select the corresponding parameter set.
 Use Module 9435 to check if this parameter set is active.
 Switch the drive controller back on by using PP_AxDriveOnRequest.
