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
Setting table for inverters (VF-S15)
- Master drive
The master drive sends frequency reference to slave drives.
- 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.
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
