High-function General-purpose Inverter 3G3RX-V1 User’s Manual (I578-E1)
• Setting the Multi-function Input S1 to S8 Selection (C001 to C008) to 66 (CP1: Position command
selection 1) to 68 (CP3: Position command selection 3) enables the selection of the Multi-step
Position Command 0 to 7.
• Set the position commands in the Multi-step Position Command 0 to 7 (P060 to P067).
• If the multi-step position switching function is not allocated, the Multi-step Position Command 0
(P060) is used as the position command.
For multi-step position command input, the wait time until the inverter determines the input terminal can
be set. This prevents the transitional status before terminal input is recognized from being accepted as
an input.
Set this wait time in the Multi-step Speed/Position Determination Time (C169). Input data will be
determined as the final data if it remains unchanged for the time set in the Multi-step Speed/Position
Determination Time (C169). Note that setting a long determination time results in a slow input
response.
