When no speed selection input is set the leveling speed is taken as the speed reference.
The inverter stops when the direction signal (UP or DOWN signal) is removed.
„ 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 to leveling speed (H1- †† =83) the inverter
decelerates to the leveling speed (d1-17) when the leveling speed selection input is activated. The leveling sig-
nal has priority over the selected speed, i.e. the selected speed is disregarded. The selected travel speed must
be different from inspection speed.
The inverter stops when the leveling speed command is removed.
Leveling Speed Priority is Selected and a Nominal Speed Input is Not Selected (H1- ††
K
80))
If d1-18 is set to “2” and no digital input is set to nominal speed selection, the speed reference with speed
selection input set is nominal speed (d1-09). When the leveling speed signal is set, the inverter starts to decel-
erate to the leveling speed. The leveling speed signal has priority over all other speed signals, i.e. the interme-
diate speed 1 and 2 and the revelling signals are disregarded when leveling speed is selected.
The inverter can be stopped by removing the leveling speed signal or the Up/Down command.
CAUTION: This sequence can be risky if e.g. the speed selection doesn’t work for any reason (broken wire
etc.).
With this configuration the drive stops with a “FRL” (frequency reference loss fault) when no speed
reference input is selected during the start.
To disable the FRL detection, set parameter S3-09 to “0”.
