Below we describe how to interpret the symbols used in the block diagrams. The main block diagram
describes graphically how the converter works. Each rectangular block represents one or more read-
write parameters. The rhomboid blocks represent read-only parameters. You can find other functional
blocks in the diagram such as: GREATER THAN, EQUALTO, LESS THAN, logical AND/OR. For
all these functional blocks, standard symbols are used. Binary parameters are represented as switches
and the position in the diagram corresponds to the default value.
Reduced and extended menu
When the TPD is in the default status, only a limited number of parameters is displayed. These
parameters are the only parameters necessary for those applications where the TPD is used as a
simple converter and where the advanced functions of the converter, for example, if the TPD is used
with a numeric control or with an intelligent axis board, are not used. To switch between the limited
menu and the extended menu, enter b99.6: limited menu if equal to 0, extended menu is 1.
The parameters in the limited menu are:
Pr0 Actual speed of the motor shaft in rpm (revolutions per minute).
Pr1 Offset for the main analogue reference.
Pr2 Full scale of the analogue reference: this is the rpm value that corresponds to a reference
voltage of 10 V.
Pr8 Value of the acceleration/deceleration ramps in seconds per 1000 rpm, with a resolution of 1
millisecond. If the acceleration/deceleration ramps must be set differently, you must go to the
extended menu in order to access the Pr9, Pr10 e Pr11 parameters.
Pr16 Integral gain of the speed regulator.
Pr17 Speed regulator damping.
Pr19 Peak current supplied by the converter, expressed as a percentage of the peak drive rating.
Pr29 Number of poles of the motor.
Pr32 Rated speed (rpm).
Pr33 Rated current supplied by the converter (which can be maintained indefinitely) expressed as
rated current of the motor (A).
Pr35 Instantaneous current required by the motor expressed as a percentage of the peak drive rating.
Pb99 Bit parameter for the basic commands.
The extended menu offers access to all the parameters, instructions of the pico-PLC and SD menu in
addition to those specified above.
