In addition, the following conditions must be met:
Ø Linear V/f motor speed controlled by an analog potentiometer.
Ø Maximum speed 3000 rpm at 50 Hz (3600 rpm at 60 Hz); can be controlled by
a potentiometer via the analog inputs of the inverter.
Ø Ramp acceleration time/ramp deceleration time = 10 s
Settings for more complex applications can be found in the parameter list and in
Section 3.2.2 "Commission Overview with BOP or AOP".

The SDP has two LEDs on the front which display the
current operating status of the inverter (see Section 6.1).
When the SDP is used, the presettings of the inverter
must be compatible with the following motor data:
Ø Rated motor power
Ø Motor voltage
Ø Rated motor current
Ø Rated motor frequency
(A conventional Siemens motor is recommended)
