Angle position encoders - Import export

The absolute angle information derived by the encoder is converted into serial information by an internal parallel-serial converter and then transmitted to a receiving electronic circuit in synchronism with a clock. Important advantages are: Low number of data lines and high reliability.

Angle position measurement by means of Hall sensors and signal processing including generation of the analogue output signal. Robust brass housing – stainless steel shaft with sliding bearing – sensor circuit consisting of ASIC with Hall elements – electrical connection via connector.

The KRP model series rotary encoders are intended for connecting directly to the Ethernet/IP network. Setting the address, baud rate or terminating resistances is not necessary. The IP address is assigned via a BOOTP or DHCP server in the Ethernet/IP network.The integrated 2-fold switch enables the KRP model series rotary encoders to be used in star, tree and line network topologies.

A major hallmark of HEIDENHAIN angle encoders is their very high system accuracy. This makes them particularly advantageous in demanding applications for machine tools, measuring machines, telescopes, printing machines, etc. Because the bearing is integrated into the encoder, machine component bearings have no effect on the measuring accuracy.

A correct mechanical connection between the customer and sensor shaft ensures that the sensor precisely detects the customer shaft's rotations. A safe position is provided by the plausibility check of two sensor systems. Detected errors are evaluated. The CAN interface outputs the validated position value and speed signal via the CANopen Safety protocol within an SRDO (Safety Relevant Data Object) using 2x2 messages (normal and inverted). The rotary encoder meets the conditions of safety level SIL2 according to IEC 61508 and performance level "d" according to EN13849. The prerequisite of safety-relevant operation is a failsafe master.

Angle encoder modules from HEIDENHAIN are combinations of angle encoders and high-precision bearings that are optimally adjusted to each other. They are characterized by their high degree of measuring and bearing accuracy, their very high resolution, and the highest degree of repeatability. The low starting torque permits smooth motions. Due to their design as completely specified and tested composite components, handling and installation is very simple. Setup Since HEIDENHAIN manufactures the bearings as well as the encoders, the two functional assemblies are highly integrated. Fewer components are necessary than in conventional solutions, resulting in fewer joints. This permits a very compact and rigid design, with particularly low overall heights. Currently, angle encoder modules with hollow shafts of 35 mm and 100 mm are available.

SRP angle encoder modules are additionally equipped with an integrated torque motor. They therefore combine a motor, precision bearing and encoder with very high accuracy in one compact system. The torque motor with its very low detent torque enables extraordinarily smooth motion control. Neither disruptive detent torques nor radial forces impair the high guideway accuracy of the bearing. Thanks to their design as completely specifi ed and tested composite assemblies, handling and installation is very simple.

A positive-locking mechanical connection between the cus-tomer’s shaft and the sensor shaft ensures that the magnet in the sensor shaft precisely reflects the rotation of the cus-tomer’s shaft. With the TBN model, one rotation (i.e. max. 16,384 steps) is recorded.With the subsequent absolute transmission, the TRN shaft encoder reaches a measuring range of up to 4096 rotations. The position and speed values (PDO - Process Data Object) are output via the CANopen protocol.
