Winders　［Metalworking machines］


 Application samples

The control methods in winders are different for winding rollers and sending rollers.

[Winding rollers: Speed control]
- Vector control without sensors
- RUN and STOP by remote control
- Speed adjustment by analog input
- Speed adjustment by over-ride function

[Sending rollers: Torque control]
- Vector control with sensors
- RUN and STOP by remote control
- Torque adjustment by analog input
- Torque/Speed control switching by contact input
- Torque bias input
- Regenetating power control by braking resistor

  Setting table for inverters

[Winding rollers: Speed control] (VF-S15)
The over-ride function is using the following analog input.
- Frequency reference: VIA terminal (0 to 10Vdc input)
- Over-ride value: VIB terminal (0 to 10Vdc input)
- Actual output frequency: VIA reference + VIB reference

Title Function Setting range Recommended setting
Automatic torque boost 0 to 3 2 (Vector control and auto-tuning)
Command mode selection 0 to 4 0 (Remote)
Frequency setting mode selection 1 0 to 14 1 (VIA)
Base frequency 1 25 to 500Hz Depends on the motor
Base frequency voltage 1 50-330 (240V class)
50-660 (500/600V class)		 Depends on the motor
Motor rated capacity 0.01 to 22kW Depends on the motor
Motor rated current 0.1 to 100A Depends on the motor
Motor rated speed 100 to 64000min-1 Depends on the motor
Override function 0 to 4 2 (VIB)

Note
After setting these parameters, please perform the following steps.

(1) Connect the motor wiring.
(2) Turn on the start signal.


[Sending rollers: Torque control] (VF-AS1)
It is necessary to set related parameters for motor constant and torque control.

The torque/speed switching signal is to smooth start-up.
 - At start up (Speed control): The S3 terminal turns off with the frequency reference of the RR terminal.
 - During continuous operation (Torque control): The S3 terminal turns on with the torque reference of the RX terminal.

The torque bias input(VI) is for compensation of machine losses .

Title Function Setting range Recommended setting
V/f control mode selection 0: Constant torque characteristics ~
8: PG feedback vector control		 8
Base frequency 1 25 to 500Hz Depends on the motor
Base frequency voltage 1 200V class:50~330V
400V class:50~660V		 Depends on the motor
Dynamic braking selection 0 to 2 1 (Enabled)
Dynamic braking resistance 0.5 to 1000 ohm Depends on the resistor
Allowable continuous braking resistance 0.01 to 600.0 kW Depends on the resistor
Input terminal function selection 7 (S3) 0 to 135 112
Number of PG input pulses 12 to 9999 Depends on the PG
Motor rated capacity (motor name plate) 0.10 to 500.0 kW Depends on the motor
Motor rated current (motor name plate) 0.1 to 2000 A Depends on the motor
Motor rated rotational speed (motor name plate) 100 to 60000 min-1 Depends on the motor
Torque command selection 1 to 8 3 (RX)
Tension torque bias input selection (torque control) 1 to 8 1 (VI/II)

Note
After setting these parameters, please perform the following steps.

(1) Set F400(Auto-tuning 1) = 4(Motor constant auto calculation).
(2) Connect the motor wiring.
(3) Set F400 = 2(Continue operation after auto-tuning).
(4) Turn on the start signal.
