Product Description:

The FS1W075P22 belongs to the F SANMOTION Servo Amplifiers series produced by Sanyo Denki. Designed to drive hybrid stepping motors in positioning tasks, the amplifier converts logic-level pulse commands into phase current suited for automated axes. By managing each phase precisely, it forms the link between motion controllers and mechanical loads on assembly machines, pick-and-place stations, and semiconductor tools. In an industrial cabinet, it mounts close to the motor to minimize wiring inductance and maintain consistent current delivery through the motor leads.

Its command resolution follows a basic step angle of 0.72°, translating each pulse into that mechanical increment. Photocoupler inputs have a resistance of 220 Ω and accept pulse streams up to 250 kpulse/s, enabling precise interpolation from high-speed PLC axes. The amplifier delivers a continuous phase current of 0.75 A per phase, while transient acceleration draws on a 4 A source-current reserve. Correct timing is maintained when the incoming pulse has a maximum duty cycle of 50%. Isolation between the control logic and power circuits is supported by a minimum insulation resistance of 10 MΩ. Open-collector outputs provide 5 mA for status signals, and the protective earth scheme follows Class I requirements.

The housing weighs 0.8 kg and tolerates continuous vibration of 5 m/s² along any axis. Status lines support a maximum of 30 V, ensuring compatibility with typical 24 V field wiring. The internal insulation system withstands a test potential of 1,500 VAC for 1 minute, providing separation between the power and control circuits. Reliable operation is maintained at a maximum altitude of 1,000 m. These limits allow the amplifier to operate in industrial cabinets exposed to factory-floor vibration or installed on elevated platforms while preserving electrical isolation and stable signal handling.
