Parameters
4.2 Motor control
SIMOCODE pro - Parameterize
94 Operating Manual, 04/2017, A5E40507630002A/RS-AA/001
The "Change-over pause" parameter can be used to delay switching from "FAST"→"SLOW"
to give the motor enough time to run down.
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
s
1 for the SLOW speed
I
s
2 for the FAST speed.
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
s
1 or I
s
2 must be
according to the secondary currents of the external transformers. For more
Overload protection (Page 34).
