üSetting possible
The I x t monitoring function monitors the current load of the axis module. The monitoring
function is set so that operation
ƒ is permanently possible with a device output current = I
r
.
ƒ is possible for ££ 30 s with a device output current ££ 1.5 x I
r
.
The overload protection of the axis module can be set with thresholds:
ƒ adjustable threshold (OC7) via C0123
ƒ fixed threshold (OC5) = 100 %
After an overcurrent phase, you can calculate with a recovery phase of 120 s. For a more
precise consideration, see the overcurrent characteristic and the value 3 x
t
axis
module
( 235).
The response to exceeding the adjustable threshold can be defined under C0604.
