DDC01.1-F200A-DS09-01-FW

Product Description:

Bosch Rexroth Indramat manufactured the DDC01.1-F200A-DS09-01-FW. The 200 Amp peak current of the DDC01.1-F200A-DS09-01-FW servo drive is key for dynamic load management in high-performance industrial applications. Peak current is the highest current the drive can deliver to the motor in transient situations, such as sudden motor direction changes or fast acceleration. A driving system must produce a sudden, intense torque burst nearly instantaneously in order to move big loads rapidly despite their inertia. This is only possible if the drive can react quickly enough to provide the necessary force by handling a high peak current. This means physically a faster current flow, which means energy is transferred to the motor windings faster. The internal power electronics and thermal management are designed for transient overload resilience since the system must be able to deliver this current without overheating or triggering protective measures.

The drive’s voltage tolerance range allows it to run smoothly, even with the typical variations found in industrial power systems. The voltage can withstand input variations without affecting performance since it has already been rectified and filtered within the system before it reaches the DC bus. The lifetime of linked components is increased, and unplanned shutdowns are less likely, thanks to this internal stabilization, which maintains the DC bus voltage within acceptable operating bounds. The amount of energy available for torque and speed is determined by the supply voltage. So variations must be controlled to avoid undervoltage or overvoltage situations that can affect servo behavior. Three-phase systems are also better for high inertia loads since they naturally provide smoother torque profiles, lower line currents per phase and less harmonic distortion.

Also, the sealed housing prevents water ingress, which can occur during cleaning or condensation in humid areas. An integrated dynamic DC bus braking mechanism further improves this drive’s performance and protection. The servo motor acts as a generator, supplying current back into the DC bus when the load is decelerating or regenerating. Internal components can get damaged if the DC bus voltage rises above the operating limits without a proper dissipation mechanism. The dynamic braking system uses resistive components to convert electrical energy into thermal energy while keeping the voltage stable. When energy recovery and regeneration surge suppression is required in applications with high inertia, sudden stops or frequent speed reversals, this is crucial. The drive will run safely under dynamic load profiles because the brake resistor’s thermal rating can withstand many cycles without degrading.
