Setpoint position (16 or 32 Bit)
With the special extension Posicon (SK XU1-POS) of the SK 700E the absolute setpoint position can be
transferred as a 16 or 32 Bit value in Setpoint 1, whereby the resolution is 1=0.001 rotation. In addition, the
control terminals (setting of POSICON control bits) can be transferred in binary.
The SK 53xE / SK54xE version of the SK 500E series is also able to transfer positions, however here, the
32 Bit position is divided into two 16 Bit components (Low word and High word). The assignment of the two
16 Bit components is then carried out via appropriate parameterisation on 2 arbitrary setpoints (e.g.: SW1
and SW2).
16-Bit setpoint position setting:
As a 16 Bit value, a range of +32767 (= 32,767 revolutions) to -32768 (= -32,768 revolutions) is possible.
The 16 Bit setpoint position is transferred as the second word in the process data area (as with the setpoint
frequency)
32-Bit setpoint position setting:
As a 32 Bit value, the full position range of +/- 50000,000 revolutions is available. With the SK 700E/750E,
the 32 Bit setpoint position is transferred in the area of the process data as the second and third word (with
the SK 500E in any two of the three words PZD2, PZD3, PZD4).

Control Bit settings POSICON (SK 700E/750E/53xE):
A 16 Bit value is transferred in which the control terminals of the POSICON special extension unit are
mapped. The setpoint position is based on the position array or position increment as per (P610).
The transferred Bits have the following meaning (see Manual BU 710 / BU 0510):
Position array/position increment
Position array/position increment
