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.
