PARAMETERS
Energy saving monitor list
• The items that can be monitored on the power saving monitor (Pr.52, Pr.54, Pr.158, Pr.774 to Pr.776, Pr.992 = "50") are
indicated below.
(Only [1 Power saving] and [3 Average power saving] can be set to Pr.54 (terminal FM, terminal CA) and Pr.158 (terminal AM).)
• The items that can be monitored on the cumulative energy saving monitor (Pr.52, Pr.774 to Pr.776, Pr.992 = "51") are
indicated below.
(The monitor value of the cumulative monitor can be shifted to the right with Pr.891 Cumulative power monitor digit
shifted times.)
