6.2 Registers groups
The registers are accessible to the user, they store all the controller’s internal values. Each register has an
identification number preceded by a letter corresponding to its group. To have the motor working correctly, it is
necessary to set the values of the registers belonging to the K group, called parameters. There are 6 main
types of registers, 3 are basic (always used) and 3 are advanced (for specific applications only):
6.2.1 Basic registers
K, for parameters Also called setting parameters. They define the motor, encoder, regulator gains and
the protections (maximum current, maximum position error, over-temperature, etc).
Each of them may be modified, by ETEL engineers and trained personal only.
M, for monitorings Also called monitoring variables. They are exclusively used to monitor the
controller’s internal values such as motor speed, acceleration, motor current, etc.
Note: They can only be read, and no value can be assigned.
X, for variables Also called user variables. They are variables that the user may freely use for
programming. Each user variable function may be defined in a program, according
to the user's needs. Values can be stored in variables and read at any time.
Examples: Parameter K1 describes the proportional gain value of the position loop.
X13 variable describes the 14
th
user variable.
M11 monitoring indicates the motor real speed.
6.2.2 Advanced registers
R, for RTIs Also called real time interrupts (for advanced users only), they allow the execution
of an immediate function. The sequence execution may jump to a defined label,
under some conditions. Refer to §13.8
for more information.
E, for triggers Also called triggers events (for advanced users only), they are used if the user's
sytem has to react specifically when the motor reaches some defined positions.
Refer to §13.9
for more information.
F, for float Also called floating-point variables (float-32 registers), used by the controllers
mathematical functions (all other registers in the controller are integer). Refer to
§14.6
for more information.
L, for LKT Also called look-up table movement (for advanced users only), they allow the
execution of a movement with a user-defined trajectory. Refer to §3.1.1.1
and
§13.3.2
for more information.
T, for trace It allows the acquisition of the registers X, K, M and L of the controller according to
the time, used by the ’Scope’ of ETEL Tools. Refer to ’EBL2 Communication
Manual’ for more information.
S, for sequence It allows the user to write/read a user’s programmed sequence. A ’download/upload’
menu is available from each tool of ETEL Tools to use the sequence without using
the S registers (transparent for the customer). Refer to §8.5.3
for more information.
