Product Description:

The DM 30K 8001-D is a servo drive module produced by Bosch Rexroth Indramat for the DM Servo Drives series. In multi-axis machinery, this device converts intermediate bus energy into three-phase motor power. It also supplies feedback-controlled current for precise speed or torque regulation on automated production lines. The compact format suits cabinet layouts where several axes share a common power section.

With a module width of 50 mm, the drive fits densely on rail assemblies while still exposing terminal access at the front. It delivers a line-to-line output of 3-ph 400 V and provides a continuous armature current of 14 Arms when the pulse pattern is clocked at 4 kHz. Under the same switching rate, it can supply up to 29 Arms for transient overloads during acceleration. For installations that favor quieter magnetic behavior, the internal IGBTs can be commutated at a carrier of 8 kHz; at that frequency, the rated and overload currents are reduced according to the derating slopes of 0.35 A/K and 0.24 A/K between 45 °C and 55 °C. The nominal output current measured at 400 V is 8.2 A, and the DC bus is charged by an 8.5 A supply drawn from the common converter.

The intermediate circuit operates on a non-regulated potential of 715 VDC, which is actively held to a regulated level of 670 VDC by the shared supply section to stabilize motor flux during load swings. Thermal design limits internal dissipation to 156 W, so cabinet ventilation must remove this heat to preserve component life when the carrier is set to the higher frequency. Command values arrive through an analog 10-bit setpoint channel, permitting simple PLC voltage references while still providing fine resolution of speed demand. A 1.03 A auxiliary feed at 24 V powers the logic and gate drivers, and when the switching frequency is held at 8 kHz, the continuous and peak outputs fall to 9.7 Arms and 22 Arms respectively.
