8 Programming digital inputs/outputs
8.1 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 b99.13 must be set to zero
. The default parameter setting (b99.12)
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:
Program steps 256
scanning time 6,144 ms
number of timers 2
number of instructions 15
stack depth 1
mathematical operations 16 / 32 bits
fast inputs 2 - (512 μs)
