3 Product families
The structure of the product family is modular. Depending on what is required of the encoder, the basic
encoder and bus covers can be combined at will with the selected bus system.
The basic encoders differ in terms of accuracy, ambient conditions and the sampling system used.
Bus cover
The bus cover contains the entire electronic circuitry for measured value processing and the Ethernet
communication.
magtivo
®
has a resolution of 1024 steps per revolution with 10 bit, features a magnetic sampling system and is suitable
for operation in extreme ambient conditions.
multivo
®
has a resolution of 8192 steps per revolution with 13 bit, features an optical/magnetic sampling system and is
suitable for standard applications.
activo
® /multivoPlus
features a 18 bit resolution of 262144 steps per turn, applies an optical/magnetic sensing method with
integrated analogue/digital conversion and is intended for ultra-precise sensing applications.
The basic encoder comprises a singleturn and a multiturn encoder. The multiturn encoder features a 16 bit
resolution respectively 65536 turns, or a 14 bit resolution corresponding to 16384 turns (multivoPlus). The
bus covers differ by their integrated bus interface.
Available bus interfaces: CANopen, DeviceNet, EtherCAT, Ethernet/IP, LIGHTBUS (fiber-optic), Profibus-DP,
Profinet, Power over EtherCAT (PoE), Powerlink, SAE J1939, SSI.
Except for encoders with fiber-optic interface, all encoders enable parameterization by bus interface.
