●
Parameter: B (Reads maximum voltage-1), Parameter: C (Reads minimum
voltage-1), Parameter: N (Reads maximum voltage-2), Parameter: P (Reads
maximum voltage-3), Parameter: Q (Reads minimum voltage-2), Parameter: R
(Reads minimum voltage-3)
• Function
Reads the maximum voltage-1 by parameter: B, the minimum voltage-1 by parameter C,
the maximum voltage-2 by parameter: N, the maximum voltage-3 by parameter: P, the
minimum voltage-2 by parameter: Q, and the minimum voltage-3 by parameter: R.
