3.4.9 Direction selection switch and potentiometer SK TIE4-SWT and SK TIE4-POT
The R and L digital signals of the direction selection switch SK TIE4-SWT can be applied directly to the
corresponding digital inputs 1 and 2 of the SK 2xxE.
The potentiometer (0-10V) SK TIE4-POT can be evaluated via the analog inputs of the frequency inverter
(only SK 2x0E) or the I/O extension. In addition, with the inverter versions SK 2x5E, an optional 24V module
(SK xU4-24V-...) provides the possibility of converting analog setpoint values into proportional pulses
(frequencies). These pulses can in turn be evaluated via one of the digital inputs 2 or 3 (P420 [02]/[03] =
26/27) of the SK 2xxE in the form of a setpoint value (P400 [-06]/[-07]).
Each of the modules (control element) is supplied
with a pre-assembled cable. This must be plugged
into the connection plug of the relevant module.
The open ends of the cable set must be wired to
the terminal bar of the frequency inverter
according to the table.
