DDS02.1-A150-D

DDS02.1-A150-D is a Bosch Rexroth Indramat unit in the DDS Drive Controllers series. It belongs to line 02 and is version 1. The controller has a rated current of 150 A and operates with a nominal DC bus voltage of 300 VDC. Its current draw is 150 mA from the -15 V supply, 150 mA from the +15 V supply, and 500 mA from the +24 V supply. The starting lockout circuit consumes 1.5 W to inhibit unintended startup.

The controller uses air supplied from outside the control cabinet for cooling, and its maximum cabinet power loss is 120 W. Its IP20 protection category guards against contact with fingers and similarly sized solid objects but does not provide water protection. The minimum earth conductor cross-sectional area is 10 mm², providing the required protective grounding path. Installation elevation is limited to a maximum of 1,000 m. The operating temperature range is 0–45ºC, while the storage temperature range is -30–85ºC.

Digital servo feedback provides motor position and speed information to the controller. The maximum feedback cable length is 75 m, limiting the permitted distance between the motor feedback device and controller. A V24 RS 232C interface provides serial communication with compatible equipment.
