Product Description:
The DMC2 51540 Motion Controller is categorized in the DMC Motion Controllers series from a reputable manufacturer Danaher which is known for precision automation solutions. The module's compact design, reliability and advanced features make it ideal for motion centric systems.
The DMC2 51540 motion controller can accurately regulate torque with torque linearity of ±1% of full scale plus and ±2% of command value. It is capable of supplying a maximum current of 11 amperes to the motor continuously without overheating or triggering protection mechanisms. The module has a physical width of 160 mm. The voltage level on the internal DC bus can stay within 570 VDC +10% / -20% and exceeding this or too low could shut down or damage the controller. It includes an inrush resistor which is used to limit the initial surge of current when power is first applied. It can safely dissipate energy when breaking the motor rapidly which prevents overvoltage on the DC bus because of an inbuilt dynamic brake resistor. Its total mass is 6.8 kg which matters for mounting, shipping and determining mechanical support requirements. The amount of braking power the controller can handle continuously through its resistor is 80 W which is useful for applications that require frequent deceleration or changes in direction.
This DMC2 51540 motion controller can continuously deliver 7.4 kW of power. This model draws 11 amperes current from the power supply during operation. All the internal power electronics such as IGBTs or MOSFETs can switch on and off with 4khz of switching frequency which affects motor smoothness and electromagnetic interference. This module comes with input AC power of a three phase, 400 V supply at 50 or 60 Hz which is essential to ensure compatibility with the available power infrastructure.
Frequently Asked Questions about DMC2 51540:
Q: How does the inbuilt dynamic brake resistor benefit the DMC2 51540 in high-inertia systems?
A: The built-in brake resistor helps safely dissipate excess energy during rapid deceleration. This prevents overvoltage on the DC bus, protecting both controller and motor.
Q: Why is a 4 kHz switching frequency important in the DMC2 51540 motion controller?
A: A 4 kHz switching frequency ensures smoother motor control with reduced torque ripple. It also minimizes electromagnetic interference for sensitive industrial environments.
Q: How does the torque linearity improve performance in the DMC2 51540 Motion Controller?
A: High torque linearity ensures accurate response to command inputs. This is vital for applications requiring precise and consistent torque control.
Q: What is the advantage of having an inbuilt inrush resistor in the DMC2 51540 model?
A: The inrush resistor limits initial current surge when powered on. It extends system life by reducing stress on internal components.
Q: Why is the 20 kJ brake energy rating critical for the DMC2 51540 Motion Controller?
A: This allows it to handle large braking events without external components. It's ideal for emergency stops or heavy-load deceleration scenarios.
