Wiring
Two or more drives with electronic limit switch-
ing can be connected in parallel to a control
point. The maximum number of synchronously
controlled drives depends on the load capacity
of the operator control.
The changeover time for switching the running
direction must be at least 0.5 seconds. The
switch and controls must not execute simulta-
neous retract and extend commands.
The following applies to operator controls with
a 5A contact load rating:
R8/17 S - R12/17 S(+) =
max. 5 drives
R20/17 S(+) - R60/17 S(+) =
max. 3 drives
L70/17 S(+) - L120/11 S(+) =
max. 2 drives
