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.

Tab. 5-192: I/O signals for multiple PID pre-charge functions
NOTES 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.
