10.4 Improved Functions
10.4.1 Moment of Inertia Ratio Setting Range
A load with moment of inertia ratio (Pn103) more than the existing maximum value 10,000% may be connected
to a direct-drive motor. Accordingly, the upper limit of Pn103 is increased to 20,000%.
* Used when the software version is 32 or later.
10.4.2 Adaptation to Single-turn Data Absolute Encoder
A single-turn data absolute encoder is mounted to SGMCS direct-drive servomotor as standard.
The machine configuration with a SGMCS servomotor does not require harmonic gear, etc. so that the servomo-
tor can be connected directly to a load. Therefore, for its absolute value detecting system, the load-end absolute
value can be obtained by measuring only the angle of motor shaft.
In this case, the encoder multi-turn data is not required and no backup battery is required.
(With a single-turn data absolute encoder, the multi-turn data is always set to “0.”)
• Single-turn data absolute encoder model: UTSB † -B ††††
Confirm the single-turn absolute encoder model in Motor Models Display (Fn011) on the digital operator or
panel operator:
• Encoder Model/Encoder Resolution Display
After executing Fn011, the following screen will appear.
