*1. The parameter FZ (RS-232C communication) selects either “Position feedback signal
øZ” or “Digital position signal MSB.” The shipping set is “Position feedback signal
øZ.”
*2. Parameter IM (RS-232C communication) selects “Integration off” or “Lower gain.”
The shipping set “Integration off.”
*3. When using a Motor equipped with brake, you may set the BRK signal to the BRKC
signal, and IOFF signal to CLCN signal by activating the brake sequence function
(BF1).
