CHAPTER 7 - PROGRAMMATION
1 - GENERAL DESCRIPTION
The SMT-BD2/m amplifiers can have up to 128 pre-programmed sequences. Each sequence can be either :
•
a homing sequence (HOME) or
•
an absolute positioning sequence (ABSOLUTE) or
•
an incremental positioning sequence (RELATIVE) or
•
a speed profile sequence (SPEED) or
•
a torque control sequence (TORQUE).
The control sequences can be automatically linked up: as soon as a sequence is over, another one can be
executed. This allows to easily solve complex axis control applications by chaining several basic control
sequences.
The SMT-BD2/m amplifiers have got 8 programmable logic outputs (triggering at the sequences execution) and 8
programmable logic inputs allowing to control a sequence start or stopping. The logic input 1 to 8 are entering the
X7 connector. The logic output 1 to 8 are located on the X6 connector. The programmation consists in initializing
the sequence parameters with the desired values. A control sequence can then be selected by using the
programmable logic inputs activation and its execution is started by using the START logic input.

-
LOGIC
INPUTS
ENABLE
Enabling authorized. This signal is a necessary conditions for the motor enabling (see also
signal RUN).
RUN
Enabling
signal.
The motor can be enabled only when the signals ENABLE and RUN are activated. Use in
priority the RUN signal if using the brake control.
INDEX/CLR
Index input for the axis homing. This input can be used for resetting the position
counter when this function is configurated.
FC+
Limit switch input, positive direction.
FC-
Limit switch input, negative direction.
