  operation  is  normal  for  10  minutes  after  a  fault  restart  is
  performed.•  When  the  fault  reset  input  is  received  after
the  protection  operation  has  been  activated  and  the  fault
confirmed.•  When  the  power  is  turned  OFF  and  then  ON
again.When  one  of  the  multi-function  outputs  (H2-01,
H2-02,  or  H2-03)  is  set  to  1E  (Restart  Enabled),  theoutput
  will  be  ON  while  the  fault  restart  function  is  in  progress.

The overtorque detection function detects an excessive

mechanical

load from an increase in the outputcurrent (or output torque).

The settings in the torque detection selection constants(L6-01

and L6-04) determine whether overtorqueconditions will be
detected and what kind of processing will be performed if a

overtorque conditionis detected.When overtorque detection is

enabled, be sure to set the overtorque detection level (L6-02 or

L6-05)and the overtorque detection time (L6-02 or L6-05).An
overtorque condition is detected when the currentexceeds the

overtorque detection level for longer than the overtorque

detection time.The overtorque detection level settings depend

on the control method:

• Open-loop or flux vector control: Set as a percentageof the motor

rated torque.

• Normal V/f or V/f with PG feedback control: Set as apercentage

of the Inverter rated current.

Any of the following functions can be set in a multi-function

output (H2-01, H2-02, or H2-03) to indicatefact that an

overtorque  condition  has  been  detected.
S  Setting  B:  Overtorque  detection  1  (NO)
S  Setting  18:  Overtorque  detection  2  (NO)
S  Setting  17:  Overtorque  detection  1  (NC)
S  Setting  19:  Overtorque  detection  2  (NC)

7Torque Limit: L7

Description of choice

Sets the torque limit value as a percentageof the motor rated
torque.Four individual regions can be set.

Torque  limits  can  be  set  separately  for  the  4  ways  that  torque
  can  be  applied:  forward  torque,  reversetorque,  forward
  regenerative  torque,  and  reverse  forward  regenerative
  torque.
