8.2 Internal registers
8.2.69 Turntable_Mode
Description: In turntable mode, the motor controls the revolution of a turntable that has the number
of positions specified in register 127, Turntable_Size.
This means the same position will be reached after rotating this number of steps in either
direction.
This register selects one of three modes that define how the motor should move to a
new position when the P_SOLL register is changed.
If the value of this register is zero, the motor will not operate in turntable mode.
Several modes of operation exist. Please also see Turn Table Mode , page 139 for detailed
description.
8.2.70 Turntable_Size
Description: If turn table mode is selected in register 126, the number of steps needed for a full rev-
olution of the turn table is set in this register. Note that the register P_SOLL must always
have a value between zero and the value in this register minus one. Negative values are
not allowed for P_SOLL or Turntable_Size.
Please also see Turn Table Mode , page 139 for detailed description.
