Winders [Metalworking machines]


"Winders" are utilize following mechanics:

- Winding rollers: Motoring
  (The force is not the same direction as motor rotation.)
- Sending rollers: Regenerating
  (The force is the same direction as motor rotattion.)

- Winding rollers
In almost all cases, the capacity of the inverter is the same as the motor capacity.
However, if you have a fixed acceleration/deceleration time or over 200% starting torque, The inverter capacity should be larger than the motor capacity.

- Sending rollers
Please install braking resistors or regenerating converters(RC7 series), because sending rollers are always in regenerating mode.
If the regenerating torque is larger than 80% of the motor rated torque, you have to increase the inverter capacity.
