Industrial Systems
Inverter for sync control system VF66AD/VF66PD
These are advanced function models equipped with the sync control function and high-precision drawing control function of the continually evolving VF66SV.
Features/functionality
VF66AD: Absolute sync control
We have commercialized absolute sync control and delivered countless commercial rotary press drive systems. Absolute sync performs rotation commands and motor rotation feedback via numeric data. To achieve a resolution of 33,554,432 Digit/r, SHPC-175-Z is used for the rotation command module and an absolute encoder for the motor.
| Absolute rotation command module |
|---|
| SHPC-175-Z |
| Rotation position commands and rotation speed commands are sent via our proprietary sync communication |
| For high-precision draw and sync control |
| Minimizes delay between sections when accelerating/decelerating |
| RS422 |

VF66PD: Incremental sync control
The VF66PD is the successor to the VF64SDS inverter. It applies incremental sync control to the VF64SDS inverter, and we have already delivered countless numbers to our customers. VF66PD’s sync control uses a PG emulator module that generates A, B, Z phases in commands. It uses SHPC-172-Z as a PG emulator module and an incremental encoder for a motor, thereby achieving 76,800 P/r.

| Minimal delay between sections when accelerating/decelerating |
| RS422 or optic fiber |

Example application to sectional drive system
This is an example of applying VF66AD to a shaftless rotary press. It achieves a speed control precision of ±0.001% and delivers sectional drive at a precision never before possible. The bottom step represents the speed command for the motor, and the top waveform represents the changes in rotation position error ΔP.
