EXTERIOR FAULT ,(SETTING,20-2F)
This is to set how to output the warning to exterior when the exterior equipment is at fault or in a abnormal status and the inverter stops. as the input condition for exterior fault , it can choose the inverter,s action when the exterior is input . the following setting group of 3 items , please fill in the suitable setting 20-2f . input level ,a contact /b contact . detection method ,fault detection / detection during operation . action selection , decelerate to stop /coast to stop/continue to operate .
DC BRAKING COMMAND (SETTING, 60)
off = normal action
on = to effect dc braking when stopping the inverter ,( initial excitation in vector control with pg ).
when inverter stops , it is used to prevent the motor from running which caused by inertia or exterior force . when inverter stops , it is used to excite dc braking action when dc braking command is on .
when operation command or jog command (jog frequency selection , f jog r jog ) is input dc braking command will be discharged , then the motor starts operation .
The sampling /dwell of analog frequency command . is only effective for terminal 13 ,14 ,16 or the analog input from a1 -14 u , a1- 14 b .
setting error (ope 03) will occur when 2 or more are set among acceleration/deceleration stom (0a) up/down command (10,11) acceleration / deceleration speed command (1c,1d ) analog frequency command sampling /dwell (1e) input level please set on or off or the signal to be the fault detection . detection method please normal or in operation to detect the fault . normal detection to detect when switching to the power supply . detection in operation : to detect only when the inverter is in operation . action selection is to set the disposal of the detected fault . decelerate to stop : to decelerate to stop with in the set time when fault is detected . coast to stop : output is abnormal and inverter cuts output . emergency stop : the output is abnormal the inverter decelerate to stop with in the set time in constant c1-09 (emergency stop decelerating time ) . continue operate to output warning to exterior and continue to operate . to output warning please set one of the multi function output h2-01 , 02 and 03 to be 10 two or more multi function input can not the same exterior ablor function to set the exterior fault it i different from other parameters and it is of hierarchy scheme .
