Input of the target position by an external control (here: PLC)
l The setpoint position is determined by cyclic set phase increments (t
sync−cycle
) in increments of
milliseconds ("150μs).
The input must be crystal−precise in the long term.
l The POS function block calculates the speed and the acceleration.
l Inputs in v
max
(C1240) and a
max
(C1250) have no effect.
l This means that speed profiles are possible in any form (e.g. cams).
l Activation by POSD−PSET−SWT = HIGH (e.g. FIXED1)
