SYNTHETIC ENCODER
SETUP::PHASE CONTROL::SYNTHETIC ENCODR
(Virtual Master Simulator) This function generates A, B, and Z pulses, equivalent to an encoder following either the virtual
master or the motor shaft or the load position (see SOURCE parameter).
Parameter Descriptions

MODE SELECT

Some versions of hardware support the direct repeat function. That is, the outputs of either the feedback encoder, or if fitted,
the reference encoder, may be electrically buffered and switched directly to the output pins. To select this function, select
RPEAT FBK ENCODER or RPEAT REF ENCODER as desired. Otherwise select RUN SYNTH ENCDR to run the
synthetic encoder.
Enumerated Value : Mode Select
SOURCE
This selects the input to the synthetic encoder. Selecting V MASTER POSN will cause the synthetic encoder to directly
follow the virtual master. It can also be set to follow the feedback or reference encoders. Note that this is not the same as
selecting the direct electrical repeat in MODE SELECT. Both the feedback and the reference encoders have a software
gearbox function, which continuously calculates the position of a load on the other side of a gearbox connected to the motor
shaft or reference shaft. It is possible to select the synthetic encoder to follow the encoder shaft directly, or to follow the
position of the load on the other side of the gearbox. For example, to follow the feedback encoder directly, select FBK ENCR
SHAFT, and to follow the load on the other side of the gearbox, select FBK ENCR LOAD.
