Figure 6-5 Action of skip frequency/speed 1 and skip band 1
When the frequency/speed (input) reference ascends into a skip band,
the resulting (output) reference remains at the lower edge of the band
until the input reference has reached the upper edge of the band. The
output reference then jumps to the value of the input reference.
When the frequency/speed (input) reference descends into a skip band,
the resulting (output) reference jumps immediately to the lower edge of
the band.
Example
Skip speed 1 = 250rpm
Enter 250 in Pr 0.20
Required skip band = 60rpm
Enter 30 in Pr 0.21
(Skip band = 2 x Value of skip-band parameter.)
6.2.9 Analog input modes
Set the required mode as follows:
A signal applied to an input terminal is converted into a value which is
applied to a parameter. The function of this parameter determines the
function of the terminal.
By default, terminal 7 (Analog input 2) is assigned to Pr 1.37 Analog
reference 2. Use Pr 0.26 to change the function of terminal 7.
6.2.10 Miscellaneous
European configuration
Use Pr 0.27 (Pr 8.27) to select the logic polarity of the digital inputs, as
follows:
Refer to Pr 6.04 in the Unidrive Advanced User Guide.
European configuration
The values of Pr 0.28 and Pr 0.29 affect the dynamic performance of the
drive in the following conditions:
• Current-limit in frequency/speed control
• Torque control
• Braking when Pr 0.15 Ramp mode selector is set at Stnd.Ct
(default)
• Synchronizing the drive to a spinning motor (Pr 0.39 set at 1)
• Loss of AC supply when Pr 6.03 AC supply loss mode selector is set
at ridE.th.
For information on adjusting these parameters, refer to Pr 4.13 and Pr
4.14 in the Unidrive Advanced User Guide.
USA configuration
Pr 0.28 differs from Pr 0.11 Pre-ramp reference in that it indicates the
demanded reference before frequency/speed limiting and skip bands.
USA configuration
Use Pr 0.29 to change the function of the digital input on terminal 29.
The default setting (Pr 1.41) gives LOCAL/REMOTE switching.
