VB1 series High Speed I/O function
VB1 main unit in the VB-PLC family is designed specifically for positioning control.
The build-in 4-point High Speed Pulse Output, 20 KHz from YO, Y1 and 200 KHz from Y2, Y3, enable the positioning control to be carried out easily in a faster and more precise manner through using the positioning control instruction. Moreover, for the High Speed Input, not only did it preserves the VB series interrupt input and high speed counter functions, some improvements have been made to it by adding a 2-point AB-phase high speed counter hardware which can count the pulse input signal frequency up to 200 KHz. The conjunction of the high speed pulse output and the high speed counter hardware can complete a close loop positioning control to satisfy the need for accuracy.
PID control with Auto Tuning (AT) mechanism
VB series PLC offer more precise process control via the PID control instruction which can be executed repeatedly. With the premium Auto Tuning (AT) mechanism, the PID parameter setting could never be easier.
Data Bank Provides Large Capacity of Data Storage Function
The Main Unit has 7,680 general and 512 latched data registers. To insert a VB-DB 1R Data Bank expansion card, it will get extra 128,000 latched data registers, for a storage of huge data is required.
VB0. VB2 Series Pulse Output Function
The Main Unit has two points (YO, Y1) of pulse output (up to 7kHz). The output pulse can drive the step motor or servo motor directly.
The additional VB-1PG positioning control module is designed for the demand of higher frequency (up to 100 kHz) pulse output.
Interrupt Input and High-Speed Counter Function
The Main Unit has 6 points (XO~X5) of high-speed input which can be used as the interrupt and high- speed counter inputs. At most, it can be connected to 6 single-phase high-speed counters or 2 AB-phase rotation encoders. The additional VB-1HC high-speed counter module is designed for the demand of higher frequency (up to 45kHz) pulse input.
This state-of-the-art Multi-Functional Display can be used to show the error messages, procedural flows, texts and graphics, etc.
When the Multi-Functional Display cooperates With input buttons, it becomes a part of data access interface. A better utilization will help enhance product added value.
