Change-over pause
The "Change-over pause" parameter can be used to delay switching from "FAST"→"SLOW"
to give the motor enough time to run down.
Safety guidelines
Note
You need at least one digital module for this control function. This control function cannot be
implemented with bistable relay outputs.
Note
Two current settings must be set for this control function:
• I
• I
Depending on the current range, the current can in many cases be directly measured at both
speeds with a single current transformer. Otherwise you will need two external current
transformers appropriate for the relevant speed (e.g. 3UF18 with a 1 A secondary
transformer rated current), whose secondary cables must lead through the current
measuring module within the range 0.3 to 3 A. The current setting I
converted according to the secondary currents of the external transformers. For more
information, see Chapter Overload protection (Page 34).
