3.2 External braking resistor (option)
The Power Modules PM240-2 are assigned to fixed values of the braking resistors:
0.37 kW, 1 AC 230 V, 390 ohm, peak power = 1.5 kW
1.50 kW, 3 AC 400 V, 150 ohm, peak power = 2.75 kW
2.20 kW, 3 AC 400 V, 150 ohm, peak power = 2.75 kW
3.00 kW, 3 AC 400 V, 80 ohm, peak power = 4.0 kW
The peak power is limited to a maximum of 12 sec. in an interval of 240 sec., if there is no performance in the remai-
ning period. It may be necessary to test the stopping time.
