Commissioning; Starting Up The Device - Nord Drivesystems SK 300P Series Manual

4 Commissioning

WARNING
Unexpected movement
Connection of the supply voltage may directly or indirectly set the drive unit into motion. This can
cause unexpected movement of the drive and the attached machine, which may result in serious or
fatal injuries and/or material damage. Possible causes of unexpected movements are 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
– Incorrect encoder connection
– Release of a mechanical holding brake
– External influences such as gravity or other kinetic energy which acts on the drive unit
– In IT networks: Earth fault (short circuit to earth)
• 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 Starting up the device

To establish basic operation capability, after the mechanical installation of the device on a suitable
wall or mounted on the motor, the electrical connections must be made ( Section 2.6.5 "Electrical
connection of power unit").
The supply with 24 V DC control voltage is mandatory for commissioning the device.
Information
Factory settings
Before recommissioning it must be ensured that the device is in its factory settings (P523).
Parameters are pre-set (factory settings).
Set the correct motor data and the selection of the operating mode in the parameters. Adaptations to
the drive application, communication settings for other devices or a control unit, as well as optimisation
of the operating characteristics are also carried out via parameter settings (see 5 "Parameter").
For the correct operation of the drive unit, it is necessary to enter the motor data (rating plate) as
precisely as possible. In particular, automatic stator resistance measurement using parameter P220 is
recommended.
Motor data for IE3 motors are provided via the NORDCON software. With the aid of the "Import motor
parameter" function (also refer to the NORDCON software manual
can be selected and imported into the frequency inverter.
