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.
WARNING
Unexpected movement due to changes in the parameterisation
Parameter changes become effective immediately. Under certain conditions, dangerous situations
may occur, even when the drive is in standstill. Functions such as
P428 “Automatic starting” or P420
“Digit inputs” or the “Brake off” setting can put the drive in motion and put persons at risk due to
moving parts.
Therefore:
• Changes to parameter settings must only be made when the Frequency Inverter is not enabled.
• During parametrisation works, precautions must be taken to prevent unwanted drive movements
(e.g. lifting equipment plunging down). The danger area of the system must not be entered.
