Features, Application | Control equipment, tool Applied actuator |
|
|---|---|---|---|
| Feedback control method | Micro deviation Automatic control |
High precision, fully automatic tension control using an automatic closed loop control. Can maintain a continuous tension value. By using a micro deviation detector, there is no delay in mechanical response. |
●Electromagnetic powder clutch/brake ●Hysteresis clutch/brake ●AC servo motor |
| Dancer roller automatic control |
High precision, fully automatic tension control using an automatic closed loop control. Wide range torque control. Able to be installed on a wide range of machinery. |
SNW type automatic controller SEP type detector ●Electromagnetic powder clutch/brake ●Hysteresis clutch/brake ●Tension brake |
|
| Open loop control method | Roll diameter proportional type automatic control |
Achieves a precise tension control by coupling the brake current to be proportional to the roll diameter. By using a non-contact detection unit, this unit is easily installable on a wide range of machines. |
●Electromagnetic powder clutch/brake ●Hysteresis clutch/brake ●AC servo motor |
| Roll diameter detection type automatic control |
By using twin detectors, the roll diameter can be identified and controlled with great precision. |
Pulse encoder
●Electromagnetic powder clutch/brake ●Hysteresis clutch/brake ●AC servo motor |
|
| Touch roll type automatic control |
Achieves a precise tension control by coupling the brake current to be proportional to the roll diameter. Since the material is detected directly, we can achieve high-precision tension control. |
