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.
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).
