During startup
During startup, make sure that:
• The motor is running properly (no overload, no speed fluctuations, no loud noises,
etc.)
• The proper braking torque is set according to the specific application (see chapter
"Technical Data")
In case of problems, refer to the "Malfunctions" chapter for more information.

Startup procedure for MOVITRAC
®
B
Observe the following points during startup:
• Use the MOVITOOLS
®
MotionStudio software, version 5.70 or higher, for a guided
startup procedure.
• Startup and operation of the motors of category 3 is possible in parameter sets 1 and
2.
• The system configuration only allows for individual drives.
• You can set either "V/f" or "vector-controlled" for the control mode.
• For the application, you can only select speed control and hoist application. Do not
use the options "DC braking" or "Flying start function".
• Always set the operating mode to "4-quadrant operation".
• Select the proper motor series in the "Motor type" window.
• In the "Motor selection" window, choose the device category, the line voltage, the
motor voltage and the connection type in addition 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
.
INFORMATION
When you start up the frequency inverter, observe the operating instructions of the re-
spective frequency inverter as well as the operating instructions of the gear unit if you
use a gearmotor.
