8.2 MIS23x Registers
8.2.64 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.
In mode 1, the motor will always move to a new position by turning in a positive direc-
tion. So to move one step backwards, it must instead move Turntable_Size-1 steps
forward.
In mode 2, the motor will always move to a new position by turning in a negative
direction.
In mode 3, the motor will move in the direction that takes the smallest number of
steps to reach the new position.
Note that the motor will not move at all if the new position in register P_SOLL is either
negative or larger than the value of register 127, Turntable_Size.
8.2.65 Turntable_Size
Description: If turntable mode is selected in register 126, the number of steps needed for a full revo-
lution of the turntable 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.
8.2.66 NL_Mask
Description: Selects which one of the eight IO pins to use for the dedicated function of Negative Po-
sition Limit.
Exactly one bit must be set, and the IO pin must be configured in register 125 as an
input.
Example: If input 7 is to be used for the Negative Input Limit, write 26 = 64 to this
register.
