6.5 Frequency setting by external terminals
6.5.1 Multi-speed setting operation
(Pr. 4 to Pr. 6, Pr. 24 to Pr. 27, Pr. 232 to Pr. 239)
The frequency inverters have 15 fixed setting frequencies (speeds) which can be preset by the
user as required via parameters 4, 5, 6, 24 to 27 as well as via parameters 232 to 239.
Any speed can be selected by merely turning on-off the contact signals (RH, RM, RL, REX
signals).
The above parameters allow its setting to be changed during operation in any operation mode
even if "0" (initial value) is set in Pr. 77 "Parameter write selection".
The above parameters can be set when Pr. 160 = 0.
