Product Description:
The SERVOSTAR-400-A is a particularly advanced type of servo amplifier engineered to generate precise control over brushless synchronous servomotors and asynchronous motors. This is done in tasking industries requiring lot of usage of controls reliably.
Among important parameters, there is the switch-on threshold for the brake circuit fixed at 720V and overvoltage threshold (F02) at 800V practical guard against overvoltage circumstances. The internal brake resistor (RBint) has internal resistance zing of 91 Ohm with 20W continuous power with maximum brake power of 0.33 kW (average over 1 second) and pulse brake power 7 kW. For an even more rigorous braking application, an external brake resistor (RBext) can be used and is similarly rated 90 Ohm powers with dissipating continuous power of 0.3 kW and the same pulse brake power of 7 kW.||The design of the unit SERVOSTAR 400-A is self-contained within a territory of designed electrical systems. It should not be linked directly to unconnected supply networks or to asymmetrically grounded power supplies of voltage more than 230V without an isolating transformer. It has been provided for occasional phase to shield over voltage up to 1000V and in the case of the amplifier module, phase to phase spiking voltages not above 1000V and Phase to Shielding Case voltages not exceeding 2000 volts well within the EN 61800 design requirements. In such instances, for use within domestic, or business premises further filtering is needed to alleviate electric fields due to the amplifier. The amplifier is designed only to be used inside sealed control cabinets which are maintained at a maximum temperature of 40 degrees centigrade for which case cooling may be needed.
Frequently Asked Questions about SERVOSTAR-400-A:
Q: What types of motors can the SERVOSTAR 400-A control, and in what industries is it typically used?
A: The SERVOSTAR 400-A servo amplifier is designed for precise control of brushless synchronous servomotors and asynchronous motors. It is particularly suited for industries requiring reliable and intensive usage of motor controls, such as automation and manufacturing.
Q: What are the braking capabilities of the SERVOSTAR 400-A, and how can they be enhanced?
A: The SERVOSTAR 400-A includes an internal brake resistor (RBint) with 91 Ohm resistance, 20W continuous power, and a maximum brake power of 0.33 kW (average over 1 second). It also supports pulse brake power of 7 kW. For more demanding braking applications, an external brake resistor (RBext) can be added, offering similar resistance with 0.3 kW continuous power and 7 kW pulse brake power.
Q: What are the voltage thresholds for the brake circuit and overvoltage protection in the SERVOSTAR 400-A?
A: The brake circuit in the SERVOSTAR 400-A has a switch-on threshold set at 720V, while the overvoltage threshold (F02) is set at 800V. These parameters provide robust protection against overvoltage conditions, ensuring reliable operation.
Q: What precautions should be taken regarding the power supply when using the SERVOSTAR 400-A?
A: The SERVOSTAR 400-A should not be connected directly to ungrounded supply networks or asymmetrically grounded power supplies with voltages exceeding 230V without an isolating transformer. The unit is designed to handle occasional phase-to-shield overvoltages up to 1000V and phase-to-phase voltages up to 1000V, in compliance with EN 61800 standards.
Q: What are the environmental and installation requirements for the SERVOSTAR 400-A?
A: The SERVOSTAR 400-A must be installed inside sealed control cabinets maintained at a maximum temperature of 40C. Additional cooling may be required to maintain this temperature. For use in domestic or business premises, further filtering is needed to mitigate electric fields generated by the amplifier.
