The three-phase DMA 15A 4101-D is a servo drive module from Bosch Rexroth with a Class A drive inverter. The drive module encompasses a+/-10V speed analog interface with a 16-bit resolution and a standard encoder interface. The single-turn encoder has a 20 bits resolution of the actual position value. The unit has a rated current of 6.1Arms and a maximum current of 18Arms at 4kHz frequency. It has a width of 50mm and a weight of 7.3kg. The servo drive can be used in several applications such as those relating to CNC machining, automation and robotics.
The drive inverter features an IP 20 protection rating in compliance with EN 60 529 specifications. The servo drive module must be installed in switch cabinets that encompass dust filters at air exits and entries. The module is one of the several such Indradyn D series devices from the manufacturer. It has a regulated DC link voltage of 670VDC. After disconnecting the drive from the mains, the covers must be removed only after about five minutes to allow de-energization to take place. The inverter has optimized mechanics for power outputs. It can be linked using control cables and DC link.
The IGBT output stage features a maximum current rating of 140A. The inverter module of the analog interface can be programmed using the DSS-D commissioning and service system. The digital speed controller and current controller of this interface have a cycle time of 62.5μs each. They have a cascade structure. The standard encoder simulation can be used to help in transmitting actual position values. Tampering with the hardware components of the unit may cause material damage or even injury. The DMA 15A 4101-D can be purchased from Wake Industrial with a one-year warranty period and shipped to any location worldwide.
