Product Description:
The SP-255 Servo Drive made by Kollmorgen is used with an input voltage that is within the range 295-360 Vdc. The main input power needed to operate the drive is 8.68 kVA. This product is best suited for systems that need accurate control and can switch between high current and frequencies in industrial automation use.
The SP-255 Servo Drive features a power under-voltage trip at 125 Vdc and an over-voltage trip at 430 Vdc. The supply voltage to the control logic is 8 Vdc minimum tolerance of 5%. The supply current of the input logic is 0.2 A. The power analog supply is ±15 Vdc, with an analog supply current of 450 mA. For 2 seconds, the maximum current is 40 A. The PWM switching frequency is rated at 8kHz. The current ripple of motors is set at 16kHz. These power levels make the SP-255 Servo Drive suitable for industrial applications where consistent performance is required. The servo drive has a working temperature of 0 °C to 45 °C. It will be stored at -20 °C and 70 °C. It has been made in such a way that it has thermal features that are efficient when used under the stipulated temperature.
This SP-255 Servo Drive is meant to be installed in some particular environment where its vibration and moisture tolerances are specified. The drive can handle humidity levels between 10% and 90%, no-condensing. It can withstand the vibration up to 0.5g. The drive may be in use at altitudes as high as 3300 feet. The continuous output of the drive is 7.3 kW at 230 VAC 3-phase input. This drive has a rated output current of 20 A. The drive has an internal dissipation of 240 W.
Frequently Asked Questions about SP-255:
Q: Why does SP 255 Servo Drive use ±15Vdc analog supply?
A: The SP 255 Servo Drive ensures stable sensor and encoder operation using ±15Vdc analog supply for precise feedback. Product code SP 255 maintains low noise and accurate control.
Q: What purpose is PWM switching frequency 8kHz for SP 255?
A: PWM at 8kHz in the SP 255 Servo Drive enables smoother motor torque control and reduced acoustic noise. Product code SP 255 achieves efficient harmonic suppression and thermal management.
Q: Why SP 255 Servo Drive features 16kHz current ripple setting?
A: The SP 255 product code sets current ripple at 16kHz to optimize motor performance and minimize waveform distortion. This enhances torque stability and reduces mechanical vibration.
Q: How does 40A peak for 2s benefit SP 255?
A: The SP 255 Servo Drive’s ability to deliver 40A for 2 seconds accommodates high torque startup demands. Product code SP 255 supports rapid acceleration in heavy-load scenarios.
Q: Why include under voltage trip at 125Vdc in SP 255?
A: SP 255 Servo Drive trips below 125Vdc to protect internal circuits from undervoltage stress. Product code SP 255 prevents irregular control behavior and hardware damage.
