4.4.2 Timing diagram during switch-on
Switch-on sequence to avoid undesired movement of the
drive. Requirement: “Stop” and “Ready” are parameterised
(

1) Optional external circuitry corresponding to section 3.2.1, e.g.variant 2.
2) Through brief switching of the stop signal, the regulator takes over the actual position as the desired position. Otherwise, the drive
can “drift” when the compressed air is switched on.

If A5 is not parameterised as “Ready” signal.
S Positioning job output not earlier than 7 seconds after the
power supply is switched on.
If E4 is not parameterised as “stop” signal.
S Make sure that the drive is in the end position when
switched on (regulation to end position).
