Operation Mode
| Mode | Description |
|---|---|
| Manual |
|
| Anti-sway assist |
|
| Automation |
|
- Depends on the speed reference by master switch operation.
- The anti-sway control mode is “OFF”.
- Anti-sway control assists the operator to reduce the load swing.
- Anti-sway control by the speed reference which is derived from automatic operation path.
- Used in conjunction with trolley position control.
Optional
- Improve the accuracy of anti-sway with angle sensor
- Minute positioning
- Anti-sway of skew with angle sensor
