When [ORT] terminal is turned ON, the orientation control is activated.
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 the [AA123] vector con-
trol 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.
Precautions for Correct Use
• For using this function, it is required to set the [AA121] control method to 10: vector control
with sensor and use the encoder feedback.
• See also 7-2-16 Encoder Feedback Control on page 7-37.
• The Z pulse (one rotation position signal) is used as the reference signal for the positioning.
(1) When the encoder is connected to the PG option unit:
Input the Z pulse between EZP-EZN.
(2) When the encoder is connected to the control circuit terminal block:
Assign the input terminal function 109:PLZ to any of the input terminal and input the Z
pulse.
(1) When the operation command is turned on while the [ORT] terminal is on, there is an acceleration
until the [AE-12] orientation speed and a constant speed is entered.
(During the operation, the speed is shifted to the orientation speed as soon as the ORT terminal is
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-11] orientation stop po one rotation for the forward
rotation and the [AE-11] orientation stop position - two rotations for the reverse rotation as a target
value.
The larger the [AE-07] position loop gain is, the shorter the deceleration time becomes.
(The deceleration time setting is not followed.)
