Incremental method (relative value control method)
This is a control method in which the distance from the current position to the target position is
specified as a relative position.
Line driver output
This is one output format used a pulse output signal circuits, in which the push-pull output of
the line driver is used. This format offers better resistance to noise than the open collector
output format. The line driver must be supported on the motor driver side. Most servo motor
amplifiers are equipped with this format.
Open collector output
This is one output format used in pulse output signal circuits, enabling to make connections in
accordance with the voltage of the power supply being used by connecting an external
resistance. This is used when connecting a driver that does not have line driver input, such as
a stepping motor.
JOG operation
This refers to an operation in which the motor is rotated only while operation commands are
being input. This is used to forcibly rotate the motor using input from an external switch, for
instance when to make adjustments. This can also be applied to unlimited feed.
Deceleration stop
This is a function that interrupts the operation in progress, slows the rotation and brings it to a
stop. This is used to stop an operation halfway.
