FB2.ENCRES

Description

This parameter sets the feedback 2 (FB2) resolutionClosed The resolution is the smallest possible movement that can be achieved by a system. It can be defined at the electronics, encoder and mechanics level. The distance a stage can be commanded to move in a single step. For servo systems, the basic increment produced by its optical encoder, or any other feedback device. and defines how many countsClosed Internal count pulses, 1 pulse = 1/2^20turn. input into the secondary feedback will be considered a full revolution.

In AKD BASIC FB2.ENCRES also defines the resolution of the virtual encoderClosed Generates an output signal directly proportional to the movement of the motor shaft. This signal is fed into the control circuitry to control the shaft position and speed. The most common types are: Incremental/Serial encoders, Hall effect sensors, Resolvers, Tachometer Generators See: Optical encoders. when using the CAMVM commands. A runtimeClosed In computer science, runtime (or run-time) describes the operation of a computer program, the duration of its execution, from beginning to termination (compare compile time). In KAS, runtime refers to the virtual machine that manage the program written in a computer language while it is running. error will occur if the you use the CAMVM commands without defining a resolution in FB2.ENCRES. If a real encoder and a virtual encoder are both used, the resolution for the virtual encoder will be that of the real encoder.
