 Setting multiple PID pre-charge functions
• When the second pre-charge function is set, two sets of pre-charge functions can be switched for use. The second pre-
charge function is enabled by turning ON the RT signal.
• The second pre-charge function parameters and signals function in the same way as the following parameters and signals
of the first pre-charge function. Refer to the first pre-charge function when setting the second pre-charge functions.

NOTE
• The second PID pre-charge function is valid also when the first pre-charge function is set to invalid and the second pre-
charge function is set.
• When "10" (second function enabled only during constant-speed operation) is set to Pr.155, the second PID function is not
selected even if the RT signal turns ON.
