If the drive has an active fault ("TRIPPED" output is colored blue) (1), then try to reset by setting the "RESET" input
= TRUE (2). Double‐click the input variable and choose "Write Values" from the "Online" menu (3).
When the "READY" output is TRUE (blue) (1), then set the "SPEED_REF" input (2) to desired speed value and
"START" input = TRUE (3). Write values from the Online menu or Ctrl+F7. Check that the drive starts and follows
the given speed reference.
Note! Speed reference is set in the block input "SPEED_REF" as a value between ‐20000 and 20000, where 20000
corresponds to a parameter in the drive (see chapter "Drive configuration").
