Project planning example

The following configuration example shows the configuration of the 24 V voltage supply on the MDX9.A-0040-5E3-4-.00 inverter with multi-encoder card CES11A and I/O extension CID21A.

The inverter supplies the DI00 digital input (output stage enable) with voltage.

The motor brake is controlled via DB00. The coil of the brake relay requires DC 100 mA at DC 24 V.

The 4 outputs of the CID21A option are each subject to a load of DC 50 mA.

Power demand of the basic unit: 20 W + 1 × motor encoder: 5 W

Power demand of the CES11A option without encoder: 0.8 W

1 × external encoder: 12 W

Power demand of the CID21A option without terminals: 0.4 W

Power demand of the inputs (basic device): 1 × 0.1 W = 0.1 W

Power demand of the brake control at DB00: 24 V × 0.1 A = 2.4 W

Power demand of the binary outputs: 4 × 24 V × 0.05 A = 4.8 W

Total power demand: 45.6 W
