Parameter setting: Frequency inverters for category 2 motors
INFORMATION
When you start up the frequency inverter, observe the operating instructions of the
respective frequency inverter as well as the operating instructions of the gear unit if
you use a gearmotor.
7.3.1
Before startup
Prior to startup, check that all the conditions for the typical application are met, see
chapter
"
). In the event of deviations from these condi-
tions, you have to calculate the maximum terminal voltage, the field weakening range,
and the torque characteristics prior to startup. The effective operating point must be
below the new thermal characteristic curve.
7.3.2
Startup procedure for MOVITRAC
®
07B
Observe the following points during startup:
•
Use the latest MOVITOOLS
®
MotionStudio software version for guided startup.
•
Startup can only be activated in parameter set 1 due to the current limitation func-
tion for motors of category 2.
•
The system configuration allows only single drives.
•
As the control mode, you can set both "V/f" and "vector controlled" (VFC).
•
Only speed control can be selected for the application. The options "Hoist", "DC
braking" or "Flying start function" must not be used.
•
The operating mode must always be set to "4‑quadrant operation".
•
Select the matching motor series in the "Motor type" window.
•
In the "Motor selection" window, choose the equipment category, the line voltage,
the motor voltage, the connection type, and the type of plant configuration in addi-
tion to the motor.
Current limit
In guided startup, the
current limit
parameter is set to 150% I
N Mot
in the application win-
dow. This value must be reduced according to the permitted maximum output torque
at the gear unit M
amax
