The following speed selection table shows the different speeds and the according digital inputs.
* 0 = disabled, 1 = enabled, X = no meaning
Higher Speed Priority is Selected and a Leveling Speed Input is Not Selected (H1-K83)
When the leveling speed command is not selected for any digital input, the inverter decelerates to the leveling
speed (d1-17) when the selected speed signal is removed. Inspection Speed can not be selected as travel speed
To select the leveling speed as travel speed the frequency reference loss detection must be disabled (S3-09=0).
The inverter stops when the direction signal Up/Down is removed.
When no speed selection input is set the leveling speed is taken as 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
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.

IMPORTANT
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”.
