4.8. Digital input and output programming
4.8.1. Pico-PLC
The internal pico-PLC makes it possible to connect peripheral systems (inputs/outputs) to
the parametric system of the HPD drive. The PLC can be used to copy a digital input into a bit
parameter, copy a bit parameter into a digital output and perform mathematical and boolean
calculations. The PLC program must be entered as a list of instructions from the keypad;
alternatively the PLC can be programmed with the ladder diagram system using a PC on the
serial line with an interface such as Pcbrush. Default parameterisation (b99.12) provides a
PLC program (see appendix G) designed to fill the requirements of the broadest possible
range of applications, therefore it is not necessary to reprogram the PLC in the majority of
cases.
Main features of the PLC:
Program steps 64
scan time 6.144 ms
timers 2
instructions 15
stack depth 1
mathematic operations 16 / 32 bits
fast inputs (fast copy) 3 - (512 μs)
