|
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. |
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. |
PCA type automatic controller 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. |
SEP type detector PS type power amp
* Electromagnetic powder clutch/brake * Hysteresis clutch/brake * AC servo motor |
| Manual control method | ||
|
|
* Wide range torque control. * Can be used with simple rollers and unwinders. * Simple handling and operation. |
* Electromagnetic powder clutch/brake * Hysteresis clutch/brake * Tension brake |
