Compact Servo Systems with SERCOS

Features BenefitsBenefits
SERCOS - Noise Free and SimpleThe PV drives with SERCOS have a high-speed and digital fiber optic interface. The controller can be up to 250 feet from the drive without any signal loss. The fiber optic interface also replaces the many logic connections in a traditional servo system. This saves time and money.
InteroperabilityThe PV drives with SERCOS include the standard set of SERCOS IDN´s (identification numbers or parameters). This means that the PV drives with SERCOS can work with AML or other SERCOS compatible controllers.
High PerformanceThe PV drive with SERCOS closes all loops internal to the drive. The position command is provided with 32 bit accuracy from the controller up to 1,000 times per second. This digital interface offers tremendous improvements in high-speed machine control over the traditional analog interface.
Separate AC Input for the Main and Control PowerThis allows the main ( motor or ´bus´) power to be disconnected during an alarm or emergency stop situation while retaining the control (or logic) power for fault analysis and retention of position feedback.
Registration InputsHigh speed inputs latch the motor position and then pass this position information to the controller. The controller can use the position and time information to ´correct´ for inconsistancies such as film stretch or other variables.
Built-in FunctionalityThe PV drives include a built-in dynamic brake to stop the motor during an emergency stop condition and a built-in regeneration circuit to handle excess energy during motor speed reversals. The holding brake control timing signal is also provided. The built-in functionality of the PE drives will tremendously simplify the electronic panel design by minimizing the need for extra external components.
