Yaskawa Sigma II Series SGMVH - Manual (Page 211)

8 Operation
8.4.2 Selecting an Absolute Encoder
8-30
8.4.2 Selecting an Absolute Encoder
An absolute encoder can also be used as an incremental encoder.
8.4.3 Handling Batteries
In order for the absolute encoder to retain position data when the power is turned OFF, the data must be backed
up by a battery.
* For Yaskawa model, a connector is included with a battery.
(1) Battery Provided for SERVOPACK
(2) Installing the Battery at the Host Controller
Prepare the battery according to the specifications of the host controller. Use the battery with the model number
ER6VC3 (3.6 V, 2000 mAh made by Toshiba Battery Co., Ltd.) or the equivalent.
Parameter Meaning
Pn002 n.†0†† Use the absolute encoder as an absolute encoder. (Factory setting)
n.†1†† Use the absolute encoder as an incremental encoder.
• The SEN signal and back-up battery are not required when using the absolute encoder as an incremental encoder.
• After changing these parameters, turn OFF the main circuit and control power supplies and then turn them ON again to
enable the new settings.
• Install the battery at either the host controller or the SERVOPACK.
It is dangerous to install batteries at both simultaneously, because that sets up a loop circuit between the batteries.
