THE TIME SEQUENCE OF OPERATION WHEN SWITCHING FROM MOTOR 1 TO MOTOR 2.



TO CANCEL PID CONTROL
off = pid control is enabled .
on = pid control is disabled ( normal control of inverter )
with this setting ,the multi - function input switches between pid control and normal inverter control . this function can be used to perform trial operation or jog operation with normal inverter control (open -loop control ) and then switch to pid control (closed -loop control using feedback) after adjusting . the system. the pid disable function can also be used to switch to open - loop control when there is a problem with the feedback value?

PARAMETERS INPUT PERMISSION (SETTING ;1 B )
off = the constants can,t be written except frequency display
on= the named constant can be input in the model of environment setting.
constant inhibition / permission from keyboard can be operated from exterior . when constant permission is off , you can only change  the monitored frequency in driving mode.

SPEED COMMAND ( SETTING ; IC )SPEED COMMAND ( SETTING : ID)
 output speed = +speed command - speed command
speed command + d4-02 = on off
speed command -d4-02 = 0ff on
speed command =on  on
speed command = off off
 speed command . the analog frequency command added by a certain value of frequency works as output frequency .
 speed command , the analog frequency command minus a certain value of frequency works as output frequency .
this function is effective only when is input from analogy terminal and  frequency command is used .
it shall be set at the same time , otherwise ope03 fault will occur . when the to signal is both on, the minus and plus calculation can't be effected .when speed command is on ,and the minus calculation result is below zero , the output frequency will be zero .
