Please note when using a braking resistor or installing a brake unit or using an energy feedback
unit
Please set P3-11 “overexcitation gain” value to “0”. If it is not “0”, it may cause excessive current
during operation. Please set P3-23 “Overvoltage stall enable” value to “0”. If it is not “0”, it may
P4 Group Input terminal
The inverter comes standard with 6 multi-function digital input terminals (X6 can be used as
high-speed pulse input terminal), 2 analog input terminals
