Toshiba Toshiba Schneider Inverter Corporation

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)


  Connection diagram of inverters (VF-S15: Master drive)

Frequency settings for each inverter use the following methods:
  Master drive: External potentiometer
  Slave drives: Inter-drive communication

Connection of VF-S15


  Setting table for inverters (VF-S15)

- Master drive
The master drive sends frequency reference to slave drives.

Title Function Setting range Recommended setting
Command mode selection 0 to 4 0
Frequency setting mode selection 1 0 to 14 1 (VIA)
Input terminal selection 6 (S3) 0 to 203 20
Regenerative power ridethrough control (Deceleration stop) 0 to 4 2
Setting of master and slaves for communication between inverters 0 to 4 3


- 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.

Title Function Setting range Recommended setting
Command mode selection 0 to 4 0
Frequency setting mode selection 1 0 to 14 4 (RS485)
Input terminal selection 6 (S3) 0 to 203 20
Regenerative power ridethrough control (Deceleration stop) 0 to 4 2
Communication error trip time 0: Disabled, 1 to 100 sec 1
Setting of master and slave for communication between inverters 0 to 4 2


  Special functions for textile machines

The VF-S15 and the VF-AS1 series has special functions for textile machines.

1. Synchronized deceleration time
  (time elapsed between start of deceleration to stop)
2. Traverse function
