Winders [Textile machines]
|
 Application samples
Winders usually use the following operating methods:
- Frequency setting through RS485 communication (Inter-drive communication)
Master drive: Input RUN/STOP operation and frequency setting.
Slave drives: Receive frequency reference from a master drive.
- Emergency stop signal input
- Regenerative power ridethrough control (deceleration stop)
Notice: When using VFS11 with RS485 communication, it is necessary to install an RS485 communication board (RS4003Z: Optional devices).
 What is RS4003Z for VFS11?
RS4003Z for VFS11 can support the RS485 communication protocol with PLCs and computers.
On RS485 networks, RS4003Z allows for a maximum of 32 connections.
Connection diagram of inverters (VFS11: Master drive)
Frequency settings for each inverter use the following methods:
Master drive: External potentiometer
Slave drives: Inter-drive communication
Notice:
The RS4003Z is a built-in terminal board that is used in place of a standard terminal board.
When you use RS485 communication, please make sure to connect the RS485 wiring to the correct terminal block.

- Slave drives
Slave drives receive frequency reference from the master drive.
The communication error trip time is useful in case a communication cable becomes disconnected or is accidentaly cut.
When the master drive trips occur, you can stop all slave drives using the F806 function.
