PAR PCU 2 indicates inconsistent power control parameters due to improper motor nominal kVA or power. The manual's first action is: “Check for the following: • 1.1 ≤ (9906 MOTOR NOM CURR · 9905 MOTOR NOM VOLT · 1.73 / P_N) ≤ 3.0 where: P_N = 1000 · 9909 MOTOR NOM POWER (if units are kW) or P_N = 746 · 9909 MOTOR NOM POWER (if units are hp, e.g. in US)”
