R911281535
Bosch Rexroth Indramat produces the R911281535 (DMD01.1-W042N), a member of the DMD series AC servo drive. It's designed to work in conjunction with the Indramat MMD servomotor and boasts a 540F capacitor with 17.82J of stored energy. The cooling occurs naturally, preventing excessive heat during operation. The device has a power rating of 400W and the wiring to connected equipment must be compact. To protect the driver, a diode is used to run a relay directly through control output terminals. The output signal serves to manipulate the brake in the motor. In case of high-speed requirements, the driver can include speed feed-forward functionality. Additionally, numerous protective features are embedded which initiate if necessary, showcasing the corresponding error code on the LED front panel display.
The overload protection function triggers after extensive continuous usage with output current exceeding its rating. A dynamic brake is included for urgent stop requirements. This can be activated when the protective function initiates or if the power supply is off. This versatile servo drive can perform in both speed and torque control scenarios. It holds an accuracy of 5mV +/ -2%. It's used with a motor having a speed of 3,000rpm and voltage rating of 230V.
