Reel parameters:
• tbO : [Reel time] : Time to wind a reel in minutes.
This parameter displays the end of the winding. If the operating time in the mode "Traverse Control" with the control command
trC reaches the value of tbO , the logic output or one of the relays in the status 1 switches if the corresponding function has
been assigned to EbO .
The EbOt operation time in "traverse control" mode can be monitored online via a communication bus and in the monitoring menu.
•
dtF :
[Reference difference]
: Reduction of the basic reference.
In certain cases, the base reference has to be reduced as the reel increases in size. The dtF value corresponds to the time tbO .
Once this time has elapsed, the reference continues to fall, following the same ramp.
If the low speed LSP is at 0 and the frequency of 0 Hz is reached, then the inverter stops and must be switched on again by
a new run command.
If the low speed LSP is not 0, the "traverse control" continues to be carried out above LSP .

• rtr : [Init Trav Contr] : Reinitialization of traverse control.
This control command can be assigned to a logic input or to a bit of a communication bus's control word. It sets the alarm EbO
and the operating time EbOt back to zero and initializes the reference again with the basic reference. As long as rtr remains at
1, the function "traverse control" is locked and the frequency remains the same as the base reference.
This control command is used especially when changing reels.
