10 Programming digital inputs/outputs
10.1 The
pico-PLC
The internal pico-PLC is used to connect the external world (inputs/outputs) with the world of
the parameters of the drive. The PLC can be used to copy digital input to a binary parameter,
to copy a binary parameter to a digital output and to execute mathematical and Boolean
operations. The PLC program must be inserted as a list of instructions by using the keyboard
To change the instructions Pb99.13 must be set to zero. The default parameter setting
(Pb99.12) corresponds to a PLC program (see
Appendix
) written for a large number of
applications. In most cases it is not necessary to program the PLC itself.
The main features of the pico-PLC are:
