Encoder program by Heidenhain has the right solution for every task and requirement: no matter if it's small, big, single or multiturn, with or without internal storage as well as optical or inductive. Both with inductive and with optical scanning, the encoders for the respective applications offer high control quality and system accuracy. In addition, there are variants with functional safety and mechanical fault exclusion, which prevents loosening of the shaft and stator connection.
Modern inductive encoders need to hide behind their counterparts with optical scanning by no means. The devices with optical scanning are still the first choice for the high end of the application spectrum. In terms of control quality and dynamics, the new inductive solutions have made good ground, they are even superior in terms of ruggedness. This is shown by comparison tests between the new generation of inductive encoders, their predecessors and optical encoders.
Quite essential for the practicality of these encoders is also that the inductive variants are in many cases cultivation compatible with the optically sampled encoders. As a result of the mechanical and electrical compatibility thus achieved, it is always possible to select the appropriate rotary encoder for the respective control requirements of the application from the manufacturer's portfolio and to minimize the number of motor mechanics. With the current inductively sampled series, the permissible mechanical mounting tolerances could be greatly extended, for example by the factor 2 for the permissible axial movement.
For easy assessment of the mechanical mounting, the encoders generate an evaluation number which the servo inverter can read out via the purely serial Endat interface. In addition, the encoders also support the monitoring of the temperature in the encoder and motor. The encoder temperature monitors an integrated temperature sensor. In addition, an external temperature sensor in the motor winding can be connected to the encoder. Both data evaluate the encoders and the subsequent electronics can read them digitally via the Endat 2.2 interface without interrupting the control cycle.
