12.17.8 Stopping at Designated Position
• How to stop the system at the designated position
for the maintenance of a machine tool.
• How to use the orientation function.
• The orientation control is available for the pulse
train position control.
• Used with the [AA121] control method set to 10:
vector control with sensor and
control mode set to 00: speed torque control mode
or 01: pulse train position control mode.
• This function enables you to determine the position
at any point within one rotation of the motor. This
can be used for replacing the main axis of a
machine tool, etc.
(1) When the operation command is turned on while
the [ORT] terminal is on, there is an acceleration
until the [AE
speed is entered.
(During the operation, the speed is shifted to the
orientation speed as soon as the ORT t
tuned on.)
(2) After the orientation speed is reached, there is a
shift to the position control when the first Z pulse is
detected.
(3) The position control is operated at the [AE
orientation stop po one rotation for the
forward rotation and the [AE
po two rotations for the reverse rotation as
a target value.
The larger the [AE
shorter the deceleration time becomes.
(The deceleration time setting is not followed.)
