Sigma-7Siec

With Rotary Servomotor
Serial encoder:
20 bits or 24 bits (incremental encoder/absolute encoder)
22 bits (absolute encoder)

With Linear Servomotor
Absolute linear encoder (The signal resolution depends on the absolute linear encoder.)
Incremental linear encoder (The signal resolution depends on the incremental linear encoder or Serial Converter Unit.)

Speed Control Range:
1:5000 (At the rated torque, the lower limit of the speed control range must not cause the Servomotor to stop.)

Coefficient of Speed:
Fluctuation+/- 0.01% of rated speed max. (for a load fluctuation of 0% to 100%)
0% of rated speed max. (for a voltage fluctuation of ±10%)
+/- 0.1% of rated speed max. (for a temperature fluctuation of 25°C ±25°C

)Torque Control Precision:
+/- 1%

Soft Start Time Setting:
0 s to 10 s (Can be set separately for acceleration and deceleration.)

Surrounding Air Temperature:

-20° to 85°C

Surrounding Air Humidity:
-95% relative humidity max. (with no freezing or condensation)

Storage Humidity:
95% relative humidity max. (with no freezing or condensation)

Vibration Resistance:
4.9 m/s²

Shock Resistance:
19.6 m/s²

Pollution Degree:
Must be no corrosive or flammable gases.
Must be no exposure to water, oil, or chemicals.
