Unexpected movement
Connection of the supply voltage may directly or indirectly set the drive unit into motion. This may
cause an unexpected movement of the drive unit and the connected machine. This unexpected
movement may cause severe or fatal injuries and/or material damage.
Unexpected movements may be due to several causes, e.g.
• Parameterisation of an “automatic starting”,
• Incorrect parameterisation,
• Control of the device with an enabling signal from a higher level control unit (via IO or bus signals),
• Incorrect motor data,
• Release of a mechanical holding brake,
• External influences such as gravity or other kinetic energy which acts on the drive unit.
To avoid any resulting hazard, secure the drive or drive chain against unexpected movements
(mechanical blocking and/or decoupling, provision of protection against falling, etc.). Ensure that there
are no persons within the area of action and the danger area of the system.
4.1 Factory settings
All motor starters supplied by Getriebebau NORD are preprogrammed with the default setting for
standard applications with 4-pole 3-phase standard motors (same voltage and power). The rated
motor current (see, for example, motor name plate) can be set for the respective motor circuit via the
DIP switch S1, which has priority in the factory settings or delivery state. If parameter P130=1 is set,
the rated motor current must be set in parameter P203 “Motor current rating”.
Hardware configuration
Make sure that the hardware configuration is mechanically possible via the DIP switch blocks S1 and
S2, the potentiometers P1 … P3 or the adjustment of individual parameters. The decision is made by
setting the parameter P130 (see 4.2.2 "Configuration").
