NOTE
A warning of low voltage will be given when 24 V DC has
been connected; however, there will be no tripping.
WARNING
Use 24 V DC supply of type PELV to ensure correct
galvanic isolation (type PELV) on the control terminals of
the frequency converter.
3.4.1.2 DIP Switches
•
Analog input terminals 53 and 54 can select for
either voltage (0-10 V) or current (0-20 mA) input
signals
•
Set switches S201 (terminal 53) and S202
(terminal 54) to select the signal type. ON is for
current, OFF for voltage
•
Terminal 53 default is for a speed reference in
open loop
•
Terminal 54 default is for a feedback signal in
closed loop
