4 PROGRAMMING OF THE APPLICATION PARAMETERS
4.1
Minimum speed, maximum speed and ramp time
The adjustment ranges of maximum and minimum speed depend on the selected motor type (i.e. motor nominal
frequency). The speeds in the speed table A are used for the 100/120Hz motors and the speeds in the speed table
B for the 80Hz motors and in the speed table D for the 35Hz motors. The maximum speed and minimum speed and
ramp time are set as follows:

1) Speeds above 100Hz are only available when the inverter is connected in 440-480V mains.
EXAMPLE OF PARAMETER SETTING:
80Hz motor is connected to the inverter and 62Hz maximum speed is desired. That speed is located on
the 5
th
row in the speedtable B. The corresponding setting for S1 swithces is in the same row in the
leftmost columns of the table: 0-1-0-0 (off-on-off-off).
