6 – 214 HEIDENHAIN Technical Manual TNC 426, TNC 430
6.12.13 Wye/Delta Connection (Only with Spindle DSP)
You can run the motor in either a wye (Y) or delta (D) connection. The
switchover can be carried out during standstill or with a revolving spindle.
Delta connections enable you to run the motor at higher speeds than wye
connections. Wye connections allow more power at low speeds. The motor
specifications must be saved for wye and delta connections in the list of
asynchronous motors. Machine parameters for current and speed controllers
are available in two settings: Index 0 is for wye connection, Index 1 for delta
connection. You can therefore switch to the optimum setting for the speed:
7
77
7 Activate with Module 9163 the switchover between wye and delta
connections.
As soon as Module 9163 is called, the NC disables the spindle drive and
activates the motor specifications and machine parameters for the selected
connection. You can check this with Module 9162.
After the connection has been changed externally by relay, activate with
Module 9161 the drive release for the main spindle.
