This function is used to switch the speed control and the position control. Allocate any of the input ter-
minal functions to 084 (SPD: (Speed/Position switching)).
Turn on this terminal when the speed control operation is performed in the absolute position control
mode.
While the 084[SPD] terminal is on, the current position monitor is 0. Therefore, when the [SPD] terminal
is turned off during the operation, the position control operation starts at that time. (Speed/position
switching)
Precautions for Correct Use
• When switching the speed to position, if the deviation between the position command and
current position is 0, the stop operation is performed immediately.
(Depending on the position loop gain, there is a possibility of hunting)
• Also, while the [SPD] terminal is on, there is a move in the direction depending on the opera-
tion command. For switching the speed to position, note the sign of the command.
Function to rotate and stop a motor and store the position as a position command at any position com-
mand area.
Assign 110[TCH].
