Explanation

●

Response of the controller (CAN−IN1)

■

Send setpoint position (from the master) to the controller

Slave 1

Slave2

Slave 3

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)
