Home return
The reference position for positioning is called a Home position and an operation to travel to a Home
position is called Home return. The home position should be set in advance. This operation moves to the
home position and its coordinate is set to be 0.
The motor rotation is reversed automatically when the limit input (+) or the limit input (-) is input and the
home position or the near home position is searched to return to the home position automatically.
Pulser operation
A manual operation is available using a device (pulser) which generates pulses manually. The output
similar to an encoder is obtained from the pulser, and the positioning unit RTEX is equipped with
exclusive input terminals. It is also called a manual pulse generator.
Deceleration stop
This is a function that interrupts the operation in progress, slows the rotation and brings it to a stop. The
deceleration time can be specified individually.
Emergency stop
This is a function that interrupts the operation in progress, slows the rotation and brings it to a stop.
Generally, a time shorter than a time for a deceleration stop is set. The deceleration time can be
specified individually.
Positioning table (Table)
A series of positioning data such as acceleration/deceleration time, target speed and interpolation
operation that is necessary for a position control is managed as a positioning table. For example, one
table is necessary for the E point control, and multiple tables are necessary for the P point control and C
point control depending on the number of pass points and continuance points.
Limit input (+), limit input (-)
This is an input to set a limit the motor movement. Limit input (+) is the maximum limit and the limit input
(-) is the minimum limit. They are connected to the AMP for the positioning unit RTEX.
Near home (DOG) input
In order to stop the table at the home position, a position at which deceleration begins is called the near
home position. This is connected to an external input switch or sensor. It is connected to the AMP for the
positioning unit RTEX.
Dwell time
In case of the E point control, a time from the completion of a position command until the operation done
flag turns on can be specified as a dwell time. In case of the C point control, a time from the deceleration
stop until the next table activates can be specified.
