Notice
Two set currents 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 converter. Otherwise you
will need two external current converters according to the corresponding
speed (e.g. 3UF18 with a 1 A secondary transformer rated current), whose
secondary cables must lead through the current measuring module with the
range 0.3 - 3 A. The set current I
s
1 or I
s
2 must be converted according to
the secondary currents of the external transformers. For further information,
see Chapter 3.2 "Overload protection".
