Advanced functions
108
1) Adds RS-485 communications to PID Feedback category.
2) PID REF value can be changed and checked in the
“rEF” of the DRV group.
Unit is [Hz] when H58=0 and [%] when H58=1
3) PID FBK value cab be checked in the
“Fbk” of the DRV group
Unit is sane with the
“rEF”
4) If PID switching is inputted to the multi-input (P1-P4), though H58 is 1, [%] is converted into [Hz].
5) Output frequency is displayed in the
“SPD” of DRV group.
6) PID OUT of Normal PID is single polarity and it is limited by H55 (H-Limit) and H56 (L-Limit).
7) 100% is F21 (Max. frequency)
Process PID drive (H54=1)
1) Speed command is the frequency (FRQ=8, except Up/Down) set by FRQ/FRQ2 and real output
frequency is sum of speed command, PID OUT1 and PID OUT2.
2) If PID switching drive is selected,
3) PID OUT1
’s polarity is double. It is limited H55 (PID upper Limit).
4) Real output frequency PID OUT2 is limited by F21 (MaxFreq) and H56 (PID lower Limit)
Other operation is same with the Normal PID.
