electric inverter torque reference

TORQUE REFERENCE DELAY TIME .
the primary delay time constant of  torque command filter is set in unit of    m r s

to adjust the electric inverter torque reference  time constant of the primary delay filmier . to adjust the noise of the torque control signal or the responsive nests with the host controller . when oscillation occurs during torque control  increase the set value . to set the primary delay time constant of torque command filter in unit of   m r s  .  increase the setting when oscillation occurs in the event of torque  control.
setting range is  1~1000 and factory setting is  0 ..

SPEED LIMIT SELECTION .
electric inverter torque reference to set the command method of speed limit in the event of torque control . 1:,analog frequency command  from the analog input limit of terminal  13 or 14 , 2:, to take the value of d 5-0 4 as the limit .

NOTE:
electric inverter torque reference in the event when d 5-0 3=1   , to take the input voltage (h 3-0 1) of frequency command (voltage) terminal 13 as speed limit when frequency reference (current) terminal 14 has been set to frequency reference by setting constant h 3-0 9 to if this terminal is also used as an input terminal for the speed limit  in this case the actual speed limit value is the sum of frequency command (voltage) and frequency command (current) . the polarity of the speed limit signal and the direction of the run command determine the direction in which the speed is limited .

electric inverter torque reference+voltage input: forward rotation ,speed is limited in the forward direction reverse rotation ,speed is limited in the reverse direction ,  -voltage inputs: forward rotation , speed is limited in the reverse direction reverse rotation : speed is limited in the forward direction . the speed limit value is zero for rotation opposite to the speed limit direction .

for example when a  + voltage is being input and the forward rotation command is on in electric inverter torque reference , the effective range of the torque control is from  zero to the speed limit value in the forward direction (when constant d 5-0 5, the speed limit bias is set to  0 ). set the signal level to match the speed limit voltage being input.setting range is 1,2  and factory setting is 1 .
 



 

SPEED LIMIT OF ELECTRIC INVERTER
to get the frequency after plus minus calculation of analog frequency command ,it is in unit of % with the maximum output frequency taken as 100% .

NOTE:
the trim control level is valid when the trim control increase command (setting, 1 c) or trim control decrease command (setting , 1 d)is set for a multi function input (h 1-0 1 to h 1-0 6) , if the trim control increase command is on when a frequency reference is input the trim control level will be added to the analog frequency reference and then output as the output frequency .

if the trim control decrease command is on the frequency reference will be decrease by the trim control level . it is set in unit of% with maximum output frequency taken as 100% . if the frequency reference minus the trim control level is less than zero ,the output frequency will be zero . refer to the description of multi function inputs (h 1)for detail on the trim control increase and trim control decrease commands.

TORQUE CONTROL SELECTION.
0:speed control (c 5-0 1~0 7 control) 1:torque control.to set d 5-0 1 to be 0 when the switching function of speed control and torque control is used to set d 5-0 1 to be 1 in the event of torque control. ( setting range 1~1000 ).
