*1. The parameter OM (RS-232C communication) selects function of OUT1 output. The
shipping set is BRK output.
*2. 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.”
*3. The parameter IM (RS-232C communication) selects the function of the Integration
OFF (IOFF) input. The shipping set is “Integration OFF.
*4. For a Motor equipped with brake, you may use the OUT1 signal as the BRKC signal
and the IOFF signal as the CLCN signal by selecting Type 8 I/O combination (TY8)
and activating the brake sequence function (BF1).
