[Pr. PC20.2_Undervoltage alarm selection]
Select the alarm or warning that occurs when the bus voltage drops to the undervoltage alarm trigger level.
0: [AL. 010 Undervoltage] occurs regardless of servo motor speed
1: [AL. 0E9 Main circuit off warning] occurs when the servo motor speed is 50 r/min (50 mm/s) or less, and [AL. 010] occurs
when over 50 r/min (50 mm/s).
[Pr. PC20.4_Input open-phase detection selection]
