Speed/Position Switching Function (SPD)
• Use this function to switch between speed control and position control.
• Allocate one of the Multi-function Input S1 to S8 Selection (C001 to C008) to 73 (SPD: Speed/Position
switching).
• While the SPD terminal is ON, the current position counter value remains 0. From the moment when
the terminal SPD turns OFF during operation, the inverter starts position control (which is referred to
as "speed/position switching").
• When the Multi-step Position Command 0 to 7 (P060 to P067) is set to 0, the inverter starts stopping
immediately when the terminal SPD turns OFF.
Hunting may occur depending on the Position Loop Gain setting.
• While the terminal SPD is ON, the inverter operates the motor in the direction based on the RUN
command. Be sure to set the RUN command so that the inverter operates the motor in the same
direction at the speed/position switching.
Parameter No.
