Product Description:
The DMC50720-AC Motion Controller operates as a precise motion controller intended for industrial applications. This product is designed by Danaher and requires 570 VDC input voltage together with an input current of 6 A. This controller generates a 3-phase output voltage, which reaches 400 VAC, together with an output current of 5 A.
The DMC50720-AC motion controller holds its DC bus voltage at 570 VDC. The optimum operation of the controller depends on a minimum motor inductance value of 8 mH. Shunt regulation activates the protection system between 670 and 700 VDC. A controller shutdown activation occurs when the DC bus voltage spans from 700 to 725 VDC to guarantee proper safety measures. The encoder functions in demanding conditions by permitting non-condensing humidity beyond 98%. The DMC50720-AC motion controller delivers a steady current of 7 A DC under operating conditions at 40°C temperature. DC operating capability extends from 0 to 60°C because the encoder functions reliably in these ambient temperature conditions. This encoder maintains vibrations of up to 18 G’s throughout a 5–2000 Hz frequency range. The controller has a temperature span ranging between -40°C to +100°C, and its storage limits reach +125°C.
The DMC50720-AC motion controller equipment comes with IP20-rated protection in a 234 x 46 x 227 mm size. This instrument functions impeccably under harsh weather conditions. This enables a continuous output power of 3 kW. The controller sustains peak current draws up to 20 A and operates with a power dissipation of 90 W. The controller operates at a speed of 1 to 9000 RPM, while output frequency ranges from 0 to 400 Hz. The controller achieves technical suitability across multiple motion control applications. This is due to its specifications, which deliver efficiency and dependable operation in harsh settings.
Frequently Asked Questions about DMC50720-AC:
Q: How does the shunt regulation improve safety in the DMC50720-AC motion controller?
A: Shunt regulation activates protective mechanisms by redirecting excess voltage to avoid damage. This ensures safe operation during voltage spikes in the DMC50720-AC.
Q: Why is a minimum motor inductance of 8 mH necessary in the DMC50720-AC motion controller?
A: It ensures stable current regulation and prevents oscillation or overheating. This helps optimize performance and protect internal drive circuitry in the DMC50720-AC.
Q: What advantage does the IP20 rating provide for the DMC50720-AC motion controller?
A: IP20 protects the controller from solid objects larger than 12mm. This ensures basic internal component protection in standard control cabinets for the DMC50720-AC.
Q: What role does the 3-phase 400 VAC output play in the DMC50720-AC controller's functionality?
A: The 3-phase output ensures smoother and more efficient motor operation. It enhances torque stability and reduces motor heating in the DMC50720-AC.
Q: Why is the temperature range of -40°C to +100°C crucial for the DMC50720-AC?
A: It allows the controller to operate in outdoor or unregulated environments. The DMC50720-AC maintains performance in extreme industrial climates.
