plus the current consumption of a holding brake and I/Os (if included)
Additional information
l A slow-blow (B16), single-phase, 16 A automatic circuit breaker must be installed
in the mains power supply line.
l If low-voltage operation is necessary, we recommend using a series transformer
or isolating transformer for decreasing the voltage.
Internal braking resistor
Characteristic Value
Braking resistor
75 Ω
Peak power 2 kW
Continuous power 8 W
External braking resistor
Characteristic Value
Braking resistor
≥ 75 Ω
Nominal power ≥ 8 W
Peak power ≥ 2,5 kW
Additional information
The external braking resistor must be connected in parallel to the internal braking
resistor. As a result, the continuous power and pulse power can be doubled if a 75 Ω
resistor is used.
