DDS02.1-A050-D

DDS02.1-A050-D is a Bosch Rexroth Indramat unit in the DDS Drive Controllers series. It belongs to line 02 and is version 1. The controller operates from a 300 V DC bus with a tolerance of ±15%. Its rated current and peak current are both 50 A, supporting the connected motor at the stated current limit. Digital servo feedback provides motor position and operating data for closed-loop control.

Cooling uses air supplied from outside the control cabinet to remove heat from the unit. Cabinet heat loss is 54 W, while external heat loss is 215 W. The controller operates from 0-45ºC and can be stored from -30-85ºC. It supports installation elevations up to 1,000 m, a maximum relative humidity of 95%, and a maximum absolute humidity of 25 g/m³. Its IP20 protection category guards against finger contact and solid objects larger than 12.5 mm but does not provide water protection.

The RS232 interface uses a 15-pin D-sub connector for serial communication. The -15 V and +15 V signal supplies each provide 150 mA, while the +24 V signal supply provides 500 mA for compatible control and interface circuits.
