3 Technical data
3.1 Features
• Three types:
- 8251 brake module with internal brake resistor for
frequent braking operations with low load or infrequent
braking with medium load for operation with 820X
frequency inverter
- 8252 brake module with internal brake resistor for
frequent braking operations with low load or infrequent
braking with medium load for operation with 8211- 8213
frequency inverters
- 8253 brake chopper with external brake resistor for
high-load continuous braking for operation with 821X
frequency inverter
• Conversion of the mechanical braking energy into thermal
energy
- Controller does not set pulse inhibit during braking, i.e.
the braking operation still remains controlled
• Very short braking times are possible
• Enclosure IP10 for installation in a control cabinet
• DIN-rail assembly possible (additional accessories
required)
• Fixed thresholds for the mains voltages 230 V (8251) and
400¼460 V (8252/8253)
• Current-state display via LED
