H58=0: Frequency Operation Concept
H58=1:% Operation Concept
Note 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.
Note 2) If PID switching drive is selected; the actual output frequency shall be speed.
Note 3) Differing with Normal PID, PID OUT1‟s polarity is double in the module, and it is limited H55 (PID
upper Limit).
Note 4) Real output frequency PID OUT2 is limited by F21 (Max. Freq) and H56 (PID lower Limit)
Other operation is same with the Normal PID.
