[2] Overview of major Functions

Function

Description

Number of positioning points

Number of positioning points which can be set in the position table.

Operation with the Position No.

Input

Normal operation started by turning the start signal ON after position No.

is entered with binary data.

Position No. direct command

operation

Operation enabled by turning the signal directly corresponding to a

position No. ON

Positioning

Positioning enabled at an arbitrary position by the data set in the position

table

Velocity change during the

movement

Velocity change enabled by activating another position No. during

movement

Pressing (tension)

Operation by an arbitrary pressing (tensile) force set in the position table

enabled

Pressing in use of force sensor Highly precise pressing enabled by measuring the current pressing force

by using a force sensor (loadcell) to control it

Pitch Feeding

(relative moving feed)

Pitch feed by an arbitrary moving distance set in the position table

enabled

Home return signal input

Input signal exclusively used for home return. Set to ON to start home

return

Pause

The operation can be interrupted or continued by setting this signal to ON

or OFF, respectively.

Jog moving signal

The actuator can only be moved while the input is set to ON.

Teaching signal input (Current

Position Writing)

Setting the input signal to ON allows the coordinate value in the stop state

to be written to the position table.

Brake release signal input

The brake (option) can only be released while the input is set to ON.

Moving Signal Output

The output signal is set to ON while the actuator is moved.

Zone signal output

The output signal is set to ON while the actuator is entered within the

zone defined by the coordinate values set as parameters.

Position zone signal output

The output signal is set to ON while the actuator is entered within the

zone defined by the coordinate values set in the position table.

Position detection feedback

pulse output

Feedback pulses sent out from the encoder can be subject to differential

output.

[Refer to Section 3.3 Operation in Pulse Train Control Mode for details.]

Vibration Control

Vibrations of the load installed on the actuator can be suppressed.

However, this is invalid in the home return and pressing operations.

[3] Operation modes of rotary actuator in multiple rotation mode and command

limitations

An actuator of multi-rotation specification includes two operation modes, or the normal mode

enabling only a limited number of rotations and the index mode

Note 1

enabling a number of

rotations. A specific operation mode can be selected by parameter No.79 “Rotational axis

mode selection”. Parameter No.80 “Rotational axis shortcut selection” allows the shortcut to

be made valid or invalid.

The table below lists the settings of parameters and the operation specification in each mode.
