Configuring the drive
Procedure
To configure the drive, proceed as follows:
1.
Select a suitable application class
When selecting an application class, the inverter appropriately sets the closed-motor control.

When selecting an application class, the inverter assigns the motor con-
trol with the appropriate default settings:
• [1] Standard Drive Control (Page 141)
• [2] Dynamic Drive Control (Page 142)
• [0] Expert - or if no application class is listed:

Standard Drive Control
Induction motors
PM240, PM240-2
Pumps, fans, and compressors with flow
characteristic
Typical correction time after a speed change:
100 ms ... 200 ms
Typical correc-
tion time after
a load surge:
500 ms
Standard Drive
Control is suit-
able for the fol-
lowing
requirements:
– Motor
power ratings < 45 kW
– Ramp-up time 0 → Rated speed (de-
pendent on the rated motor power):
1 s (0.1 kW) ... 10 s (45 kW)
– Applications with constant load torque
without load surges
Standard Drive Control is insensitive with
respect to imprecise setting of the motor da-
