FUNCTION CODES
Chap 5
■ Hold line speed control frequency in the memory -- “LSC-HLD” (Function code E01 to E05, data = 71)
If “LSC-HLD” is turned ON under line speed control, stopping the inverter (including an occurrence of an alarm
and a coast-to-stop command) or turning “Hz/LSC” ON saves the current frequency command compensating for a
take-up roll getting bigger, in the memory. At the time of restart, the saved frequency command applies and the
inverter keeps the line speed constant.
“LSC-HLD”
Function
OFF Disable (No saving operation)
ON Enable (Saving the frequency command compensating for a take-up roll getting bigger)
Shutting down the inverter power during operation stop loses the frequency compensation data saved in
the memory. At the time of restart, therefore, the inverter runs at the frequency without compensation so
that a large overshoot may occur.
