Module protection 

Output over current 

Check  whether  the  motor  the  output 
connection are short circuited, whether 
the  ground  is  short  circuited  and 
whether the load is too hea 

DC terminal overvoltage 

Check  the  mains  power  supply  and 
whether  the  large  inertia  load  has  no 
function  of  quick  stop  at  energy 
consumption brake. 

Loose connection of connectors

protection 

Input power under voltage 

Check input power supply 

Fast start−up when motor operates 
with high speed 

Start again after the motor stop rotating 

Keep overloading for a long period of 
time 

Shorten the overloading time and 
reduce load 

  Too short    acceleration or 
deceleration time 

Prolong the acceleration or 
deceleration time 

V/F curve ratio is set too large 

Adjust V/F curve setting and torque 
boost 

Power level of inverter is small 

Replace to inverter with proper model
