Absolute and incremental encoders with mounting accessories
Motion control encoders are optoelectronic built-on encoders that detect the traversing distances, angles of rotation, speeds or positions of machine axes. Motion control encoders are direct measuring systems that are built-on to shafts, axes or motors. They can be used in conjunction with numerical and programmable logic controllers, drives and position displays. Motion control encoders are system-tested, certified components that have been harmonized for use with the following systems:
- SINUMERIK CNC controls
- SIMOTION Motion Control Systems
- SIMATIC programmable logic controllers
- SINAMICS drive systems
Application
ENG_86614.XML
Motion control encoders are used with machine tools and production machines as additional external measuring systems. They are available as incremental or absolute encoders.
Incremental encoders
In the case of incremental encoders, the machine must travel to a reference point after each power-off state, as the position is not usually stored in the controller. Movements of the machine while the power is off are not recorded.
Incremental encoders are suitable for use in simple machine concepts with mostly small dimensions.
Absolute encoders
Absolute encoders, on the other hand, also record movements while the power is off and return the actual position after power on. Travel to a reference point is not necessary.
Absolute encoders are suitable for complex machines or machines with large dimensions.
Design
ENG_86615.XML
All motion control encoders are available in Synchro flange and clamp flange versions. The absolute encoders are also available with a hollow shaft and torque arm.
The motion control encoders are driven via a plug-in coupling or spring disk coupling. Alternatively, pulleys can also be used.
The motor control encoder supply voltage is 5 V DC or alternatively 10 V to 30 V DC. The 10 V to 30 V DC version supports longer cable lengths. Most control systems supply the voltage directly at the measuring circuit connector. With SINAMICS, the measuring systems are provided with power via the Sensor Modules.
For motion control encoders with cables, the cable length including the connector is 1 m (3.28 ft).
The following bending radii must be observed for the cable to the built-on encoder:
- One‑time bending: ≥ 20 mm (0.79 in)
- Continuous bending: ≥ 75 mm (2.95 in)

Power supply
Absolute encoders with EnDat, SSI or DRIVE-CLiQ and incremental encoders with sin/cos 1 Vpp, HTL or TTL fulfill the requirements of IEC 61010‑1 if power is supplied from a secondary circuit with limited energy (Low Voltage, Limited Energy) acc. to IEC 61010‑13rd Ed., Section 9.4 or from a Class 2 secondary circuit in accordance with UL 1310.
The corresponding sections of DIN EN 61010‑1, EN 61010‑1, UL 61010‑1 and CAN/CSA‑C22.2 No. 61010‑1 can be used instead of IEC 61010‑13rd Ed., Section 9.4.
Absolute encoders with PROFIBUS DP and PROFINET IO fulfill the requirements of UL 508 and CAN/CSA-C22.2 No. 14 if power is supplied from a Class 2 secondary circuit as per National Electrical Code/Canadian Electrical Code.
