Homing function

• Set SPD terminal ON, then speed control is enabled in simple positioning
mode.
• While SPD terminal is ON, current position counter is 0. When SPD is
turned OFF, the inverter starts positioning operation.
• If positioning command data is 0 at SPD turning OFF, the inverter start
deceleration immediately. (Depending on DC braking setting, motor could
be hunting.)
• While SPD terminal is ON, rotating direction depends on RUN command.
Be sure to check rotating direction after switching to positioning operation.
