REMARKS
*1. When the frequency setting potentiometer is connected, the input signal of the frequency
setting potentiometer is ignored if the multi-speed select signal is switched on. (This also
applies to the 4 to 20mA input signal.)
*2. For a reverse rotation start, set Pr. 63 to "- - -" (factory setting) to make the STR signal of
terminal STR valid.
