Summary of axis types and control modes
The following table lists the axis types and their recommended modes for
speed control, position control and torque control.

ATYPE SERVO Mode
Comment
40
OFF
Position
(MECHATROLINK-II)
The position loop is closed in the Servo Drive.
No new motion command is allowed.
40
ON
Position
(MECHATROLINK-II)
Recommended mode for position control with
MECHATROLINK-II axes.
41
OFF
Speed
(MECHATROLINK-II)
Recommended mode for speed control with
MECHATROLINK-II axes. Set the speed with
S_REF
.
41
ON
Position via speed
(MECHATROLINK-II)
The position loop is closed in Trajexia. This
gives lower performance than closing the posi-
tion loop in the Servo Drive.
42
OFF
Torque
(MECHATROLINK-II)
Recommended mode for torque control with
MECHATROLINK-II axes. Set the torque with
T_REF
.
42
ON
Position via torque
(MECHATROLINK-II)
The position loop is closed in Trajexia. The out-
put of the position loop is sent as the torque ref-
erence to the Servo Drive.
44, 46,
47, 48
OFF
Speed
(Flexible Axis)
Recommended mode for speed control with
Flexible Axis.
44, 46,
47, 48
ON
Position
(Flexible Axis)
The position loop is closed in Trajexia. Recom-
mended mode for position control with Flexible
Axis.
49
OFF
Speed
(MECHATROLINK-II)
Inverter (with built-in encoder interface) con-
trolled on the MECHATROLINK-II bus as a
servo axis. Set the speed with
S_REF
.
49
ON
Position
(MECHATROLINK-II)
Inverter (with built-in encoder interface) con-
trolled on the MECHATROLINK-II bus as a
servo axis. The position loop is closed in Tra-
jexia.
