Hengstler ACURO Drive AD37S multiturn encoder with Safety4Wire
Hengstler has introduced the ACURO Drive AD37S multiturn encoder with Safety4Wire. The Hengstler Safety4Wire interface was especially designed to provide high levels of functional safety in servo motor control systems.
The interface protocol meets SIL3 requirements according to IEC 61508, Cat. 3 PLd per EN ISO 13849, while the AD37S encoder itself and the IP core in the controller both meet SIL2.
The AD37S has an operating temperature range from -20 up to 105°C and a 12,000 rpm maximum speed, in a 28 mm mounting depth. Resolution is up to 20-bit (single turn) plus 12-bit (multiturn).
The encoder contains both an encoder temperature sensor and an input to allow connection of the motor’s winding temperature sensor, adding that information directly into the encoder’s data. An internal ‘electronic data sheet’ in the encoder stores motor and encoder data and can be recalled at any time.
