D ecrease the brake current %
L ack of phase when input current, momentary
power off, power supply point loose, power
supply voltage fluctuate s serious and make the

C heck the reason and reset
I nput power supply lack of phase, momentary
power off, power supply point loose, power
supply voltage fluctuates serious and make the
voltage between phases unbalance
C heck the reason then reset
O perate panel and CPU board connection is not
good, the control circuit of inverter is not good
