Common across the series

7
General Connection method
When an external resistor is used, the B1-B2 shorting link on the power connector is removed and the resistor is wired between those terminals
General Product type
External braking (ballast) resistor
General Resistor type 3/5
Wirewound
Electrical Overload capability
Up to 5 × rated power, for up to 5 seconds
Mechanical Connecting cable
AWG 13, 5 m maximum; shielded cable must be used and the shield earthed at least at one end (through the drive or the resistor metal housing)
Environmental Surface temperature warning
At rated power the surface temperature can exceed 100 °C; adequate cooling must be provided
Protection Protection class 3/5
IP 5X

Rows with an N/M badge are recorded on N of the M models; the remaining models do not publish that property.

Resistance inside the drive's published range

Values of 30, 40 and 60 ohm are published alongside the 400 W, 1000 W and 1500 W power classes. A combination outside the resistance range a drive publishes is never paired in the catalogue.

Keeping braking energy out of the DC bus

An axis that stops a high-inertia load quickly returns braking energy to the DC bus. The resistor turns it into heat and keeps the bus voltage inside the drive's working limit.
