6.4.5.2 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 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). With SK 52xE:
PZD1 PZD2 PZD3 PZD4
STW SW1, 32 Bit SW2
P546=3, 32 Bit setpoint position
SK 700E/750E
Posicon
SW1, 16 Bit SW2, 16 Bit SW3
P546=21 (23)
Low word
P547=22 (24)
High word
SK 53xE
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):
SK 700E + SK TU1-POS
Bit Function
Bits 0-5 Position array/position increment
Bit 6 Reference point run
Bit 7 Reference point
Bit 8 Teach-in
Bit 9 Quit teach-in
Bit 10 Reset position
SK 500E
Bit Function
Bits 0-3 Position array/position increment
Bits 4-7 Vacant
Bits 8-15 no significance
