5.9 Limiter
[5-12] Basic function "Limiter" (schematic diagram)
 The software limit positions which can be set via parameters serve to limit the travel
range by means of software and prevent that travel commands are executed which
would cause an exit of the permissible travel range.
 Moreover, the travel range limits are monitored via limit switches via the digital inputs
DI3 and DI4.
 Parameter setting: Tab Application parameters  dialog level Overview  Limiter
The basic function "Limiter" monitors the
travel range limits via limit switches and
parameterisable software limit positions
and after an according request from the
safety module can lead the drive into
defined limit ranges. Furthermore higher-
level limit values for travel profiles can be
entered and activated.

Note!
The digital inputs DI3 and DI4 are configured fail-safe in C00114/3 and C00114/
4 , i.e. a HIGH level is expected at both inputs in idle state.
• If the travel range limits should not be monitored (e.g. in case of a rotary axis),
set the limit switch inputs of the basic function "Limiter" permanently to
FALSE.
The parameterised limit values for travel profiles are not effective for the basic
functions "speed follower", "torque follower", and "position follower"!
• For the exceeding of the limit values an error response can be set.
