Note
The setting for YWAY must correspond to the mechanical leverage
ratio. The driver must be set to the value of the actuator travel or, if
this value is not scaled, to the next largest scaled value.
Initialization
Automatic initialization is started when you select “Strt” and press the
increment key (> 5 s). Initialization is displayed by “RUN 1” to “RUN 5”
(see Fig. 3-22 to Fig. 3-24) as it progresses.
Current range of setpoint
The current range you select depends on the connection type. “OmA”
is only possible for a 3/4 wire connection.
Setpoint direction (see Fig. 4-5)
The setpoint direction setting is used to reverse the direction of the set-
point. It is primarily used for split–range operation and single–acting
drives with the safety setting “up”.
Setpoint for start of split range (see Fig. 4-5)
and
Setpoint for end of split range (see Fig. 4-5)
Parameters “7.SPRA” and “8.SPRE” used in conjunction with parame-
ter “6.SDIR” are used to limit the active setpoint range. This can be
used to solve split–range tasks with the characteristic curves
