12.5.3 Parameter adjustment prior to startup
CAUTION
Danger due to:
- Unsuitable parameterization for operation with reduced supply voltage.
- Increased voltage in regenerative operation.
- Fluctuating supply voltage, e.g. with battery supply.
Potential damage to property
• Adhere to the changed values in the parameter table. Parameterize only permit-
ted values.
For operation with supply voltage, e.g.
DC 24
V, you must change the factory setting
of the following parameters:
