• Example of protective function by time limit (Pr.760 = "0")
• Example of protective function measured value limit (Pr.760 = "1")
 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 the turning ON 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.
