Chapter 7 Exclusive Functions for iS7 Inverter Control/Monitoring
7-19
6) During forward constant speed, the D4474 is h0031 (see common area of inverter)
7) With the digital loader of the inverter, change DRV01 (Cmd Frequency) to 5.00 Hz for forward
deceleration. During forward deceleration, the D4474 is h0041 (see common area of inverter)
(3) Monitoring the current output frequency of inverter
It is possible to monitor the current output frequency of iS7 inverter, and make out a ladder program for the
sequence suitable for the operation frequency in PLC option card.
▶ Common area of inverter
Referring to the parameters (exclusively for monitoring) of inverter common area in the “App. 4-1, page 4,
Appendix,” the addresses of the common area of the inverter’s current output frequencies are as follows.
