Possible cause
 PID feedback offline
 PID feedback source
disappear
 Braking circuit fault or
damage to the braking
pipes
 The external braking
resistor is not sufficient
 The output of the inverter
is short circuited with the
ground
 There is fault in the current
detection circuit
 The actual motor power
sharply differs from the
inverter power
 The output of the inverter
is short circuited with the
ground
 There is fault in the current
detection circuit
 The actual motor power
sharply differs from the
inverter power
 The load is too heavy or
fault stalled
 Check the PID feedback
 Check the PID feedback
 Check the braking unit and
 Increase the braking
 Check if the connection of
 Change the hoare
 Change the main control
 Set motor parameters

 Change the hoare
 Change the main control
 Set motor parameters
 Check the load and
 Increase the detection
 Check whether the control
