Higher Speed Priority is Selected and no Leveling Speed Input is Selected (H1-=83)
When the leveling speed command is not selected for any digital input, the inverter decelerates to the leveling
speed (d1-17) when all selected speed signals are removed. The selected speed must be different from leveling
and inspection speed.
The inverter stops when the Forward/Reverse command signal is removed.
When no speed selection input is enabled, leveling speed is the speed reference.
The following speed selection table shows the different speeds and the according digital inputs.
* 0 = disabled, 1 = enabled, N/A = not available
To make the inverter stop must be remove the direction signal(Forward/Reverse signal).
Separate Speed Selection Inputs, Leveling Speed Has Priority (d1-18=2)
The related parameters and the digital input pre-settings are the same as for the High Speed Priority setting
(d1-18=1).
Leveling Speed has Priority and a Leveling Speed Input is Selected (H1-=83)
If d1-18 is set to “2” and one multi-function digital input is set for the leveling speed (H1-=83) the
inverter decelerates to the leveling speed (d1-17) as soon as the leveling speed selection input is activated. The
leveling signal has priority over the selected speed, i.e. the selected speed is disregarded. The selected speed
must be different from leveling speed and inspection speed.
The inverter stops when all speed command is removed or the Forward/Reverse signal is removed.
Once the leveling speed is selected, the inverter keeps running at the leveling speed until above condition
meet.
