Options
With near origin and end limit sensors (option code: L)
Revolution sensors are directly connected to the output shaft on the counter-output side of the actuator.
Use this option if the mechanical origin is needed (when the virtual origin of the absolute encoder does
not do the job) or you want to define an operation range as a safety measure.
.
Side exit cables (option code: Y)
The cables (motor and encoder wires) are exited from the side face of the actuator.
Use this option if the actuator is housed in a system and there is not enough space at the rear of the
housing.
This option is not available with the SHA58 and SHA65.
For details on side exiting cables, contact our sales office.
Output shaft single revolution absolute model (option code: S)
With the standard encoder, when it continues to rotate in just one direction, the absolute encoder
eventually exceeds the number of revolutions that can be detected with multi-revolution detection and
it becomes impossible to manage position information accurately.
With the output shaft single revolution absolute model, each time the output shaft turns through single
revolution, the cumulative multi revolution counter is cleared to 0. This is how position information is
accurately managed when the shaft continuously turns in just one direction. To use this function, it is
necessary to setup a Servopack to drive the motor. Refer to the Servopack manual.
Caution:
To enable this function, the Servopack parameter Pn205 (multi-turn limit value) must be set. Since the
initial value of Pn205 is set to "65535", an alarm (mismatched multi-turn limit value) is generated when
the Servopack is started for the first time. Set the [Speed ratio -1] value for the SHA-Y series actuator
to Pn205, then turn ON the Servopack power again to enable this function.
For details on the S
ervopack parameter settings, refer to the Σ
-7 Servopack manual.
