5.3 Commissioning using a BOP-2 operator panel
Select the suitable application class
When you select an application class, the inverter assigns suitable settings to the motor

Pumps, fans, and compressors with flow
characteristic
Wet or dry blasting technology
Mills, mixers, kneaders, crushers, agitators
Horizontal conveyor technology (conveyor
belts, roller conveyors, chain conveyors)
Basic spindles
Typical settling time after a speed change:
100 ms ... 200 ms
Typical settling
time after after a
sudden load
change: 500 ms
Standard Drive
Control is suita-
ble for the follow-
ing requirements:
– All motor
power ratings
– Ramp-up time 0 → rated speed (depend-
ing on the motor power rating):
1 s (0.1 kW) ... 10 s (18.5 kW)
– Applications with continuous load torque
without sudden load changes
Standard Drive Control is insensitive to inac-
curate motor data settings
550 Hz
Unlike "Dynamic Drive Control," no speed
controller needs to be set
As compared with "configuration for experts":
– Simplified commissioning using prede-
fined motor data
– Reduced number of parameters
