NORDAC FLEX (SK 200E ... SK 235E) – Users Manual for Frequency Inverters
With device variants SK 2x0E, a power supply unit is integrated and so no external 24 V DC voltage
supply is required. For sizes 1-3 connection of an external power source (e.g. power supply unit
SK xU4-24V-...) is not provided. No connection terminals are provided for this purpose. Size 4 has
appropriate terminals and allows the connection of an external voltage source ( section 0 "Control
terminal details ").
The SK 2x5E does not have its own analog input. In order to be able to evaluate an analog signal with
this device variant (e.g. from a potentiometer), the analog signal can be converted into a pulse signal
using the power supply unit and made usable by an appropriate digital function of the device.
In order to process
(0(4) - 20 mA) the accessories kit includes a
500 Ω resistor which must be connected between
terminals 12 and 14. The relevant input on the
variable frequency
parameter P420.
