WARNING
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 machine which is connected to it. 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 start",
• 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 the drive or drive chain must be secured against unexpected movements
(mechanical blocking and/or decoupling, provision of protection against falling, etc.) In addition, it must be
ensured 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 pre-programmed with the default setting for
standard applications with 4-pole standard motors (same voltage and power). The nominal current of
the motor (see motor type plate, for example) can be set for the respective motor circuit using
potentiometer P1, which has priority in the factory setting or the as-delivered condition. If parameter
P130
=1, the nominal current of the motor must be set in parameter
P203
"Rated motor current".
Information
Hardware configuration
It must be ensured that the hardware can essentially be configured mechanically using DIP switch block S1 and
potentiometers P1 ... P4 or alternatively by adapting individual parameters. The decision concerning this is made
by setting parameter
P130
(
Section 4.2.2 "Configuration").
4.2 Starting up the device
The motor starter can be started up in various ways:
a) For simple applications (e.g conveyor applications) by means of the DIP switches (
S1
) integrated
in the device (internal), the two externally accessible potentiometers
P1
and
P2
and internal
potentiometers
P3
and
P4
.
b) By adapting parameters using the control and parametrisation unit (SK CSX-3H or SK PAR-3H) or
the NORD CON PC - supported software.
Attention must be paid to the setting of parameter
P130
when doing this. The parameter settings
are only effective if
P130
= 1!
After completing the
parametrisation
of the motor starter, the parameter values must be
transferred from the RAM memory
to the Flash memory of the device (
P550)
! Otherwise the
settings that have been made will be lost again when the device is shut off.
Note: Flash memory! Approximately 100 memory cycles are possible!
