High-function General-purpose Inverter 3G3RX-V1 User’s Manual (I578-E1)
• Set the forward/reverse position limit of the control range in the Position Limit Setting (Forward Side)
(P072)/Position Limit Setting (Reverse Side) (P073). If the current position counter exceeds the set
value, a Position control range error (E63.*/E73.*) will occur, which causes the inverter to fall into a
free-run state.
• The multi-step position command set in the Multi-step Position Command 0 to 7 (P060 to P067) is
subject to these upper limit settings.
You cannot set a position command value over the position limit setting.
