HPC800
HPC800 The DFCM-ASCII modules are the idea/ solution for the
many applications where DF1 connectivity can be used
to integrate ASCII serial input devices into a system. The
DF1 gateway is a powerful module designed with both
Master and Slave support, enabling easy connection to
Rockwell Automation PLCs (CLX, SLC, PLC, CPLX, and
similar devices).
In combination with the ASCII device
support, the module provides a very powerful interface to
the many ASCII devices which are in use in the industrial
marketplace today. Appl/ications for the module are
found in most industries, especially Manufacturing, Oil
and Gas, Electrical Power and Food Processing.

How to deal with the abnormal sound or vibration of ABB robot servo motor when it runs in repair of several faults?
Servo wiring:
Whether the power cable, encoder cable, control cable and cable are damaged; Check whether there are interference sources near the control line and whether they are parallel or too close to the nearby high current power cables; Check whether the potential of the grounding terminal changes suddenly to ensure excellent grounding.
Servo parameters:
If the servo gain is set too large, it is recommended to manually or actively adjust the servo parameters from the beginning; Acknowledge the setting of the time constant of the speed response filter. The initial value is 0, and you can test to increase the setting value; The electronic gear ratio is set too large, so it is recommended to restore to the factory setting; Resonance of servo system and mechanical system, test and adjust the frequency and amplitude of notch filter.
Mechanical system:
The coupling connecting the motor shaft and the equipment system deviates, and the mounting screws are not tightened; Poor engagement of pulleys or gears will also cause load torque changes. Test no-load operation. If it is normal during no-load operation, check whether the combination part of the mechanical system is abnormal; Recognize whether the load inertia, torque and speed are too large, and test the no-load operation. If the no-load operation is normal, reduce the load or replace the driver and motor with larger capacity. Application of Bently 3500 in steel, electric power, chemical and petrochemical industry and measuring points for vibration monitoring
The compressor belongs to the general equipment category, which is better used in steel, power,
llurgy, chemical, petrochemical and other enterprises. The following is a configuration example of Bentley vibration protection system used by the motor to drive the compressor unit through the gearbox for your reference.
Compressor unit: motor, gearbox, compressor
Typical vibration measuring points of Bently 3500 are arranged as follows:
The front and rear bearing boxes of the motor are equipped with shell vibration sensors to measure the j pair vibration of the motor bearings. The low speed end and gao speed end of the gearbox are respectively equipped with case vibration sensors to measure the j pair vibration of the gearbox. The front and rear X-Y direction eddy current sensor system of the compressor is used to monitor shaft vibration. In addition, a set of eddy current sensor system is also used to measure the compressor shaft displacement, and a set of eddy current sensor system is used to measure and monitor the key phase. The system configuration of the vibration monitoring product is as follows:
Centrifugal Compressor – Steam Turbine Drive
For units working in hazardous areas, Bentley sensors and monitoring systems should have the option of multi agency approval units. There is no requirement for the units working in the safe area.
1. Requirements for measuring point configuration
Keyphasor: each shafting of the compressor unit at the same speed is equipped with a Keyphasor measuring point; Bentley 3300XL series eddy current sensor is used for measurement.
Shaft vibration: each sliding support bearing is equipped with a pair of shaft vibration measuring points in X/Y direction (installed vertically to each other), which are measured by Bentley 3300XL series eddy current sensors.
Axial displacement: each thrust bearing of the compressor unit is equipped with double redundant axial displacement measuring points; Bentley 3300XL series eddy current sensor is used for measurement.
Bearing vibration (optional): each rolling support bearing is equipped with two bearing vibration measuring points (installed horizontally and vertically), which are measured by Bentley 330500 series Velomitor piezoelectric vibration velocity sensor.
Gearbox shell vibration (if applicable): a pair of X/Y direction shell vibration measuring points shall be provided at the support bearings of input and output shafts of each gearbox; Bentley 330400 series piezoelectric vibration acceleration sensor is used for measurement.
Overspeed protection (optional): each compressor unit is equipped with three redundant overspeed protection measuring points, which are measured by 3300XL series eddy current sensors. 2. Bently 3500 configuration requirements
