Speed/position changeover
To perform speed control operation in absolute position control mode, turn on the SPD
terminal. While the SPD terminal is off, the current position count remains at 0.
Therefore if the SPD terminal is turned off during operation, the control operation is
switched to position control operation based on the position where the terminal is
turned off. (Speed control operation is switched to position control operation.)
If the position setting is 0 at this time, the inverter stops the motor at that position.
(Hunting may occur if a certain position loop gain value has been set.)
While the SPD terminal is on, the rotating direction depends on the operation
command. When switching from speed control to position control, pay attention to the
sign of the value set in the operation command.
