Geared VVVF Controller

Mount the controller cabinet (or box) in the machine room or shaft position, level and fixed to the wall.

• Route power and signal cables in separate wire ducts to avoid interference.
• Connect the earth to the dedicated terminal — a proper ground is required for safety and EMC.
• Keep the mains supply, motor/valve wiring and the low-voltage signal bus separated.

The controller is set up from the on-board keyboard and display, with three working modes:

1. Programming — view and change the configuration parameters through the tree menu.
2. Maintenance — force movements and service functions during commissioning.
3. Monitor — read live inputs, outputs, position and speed for diagnostics.

To change a value, enter the parameter, edit with the arrow keys and confirm with ENTER.

Land the controller's wiring in this order:

• Flat cable to the car top.
• Gatebox / concentrator board in the car.
• COP (car operating panel) and LOP (landing) pushbutton boards over the serial bus.
• Sensor cable for the shaft position sensors.
• Maintenance keyboard connector on the car top for on-site service.

Follow the connection blocks / combinations table for the exact terminal assignment.

Position the slowdown magnets and stop sensors so the car decelerates and levels correctly.

• Calculate the slowdown-magnet position from the rated speed and deceleration distance.
• Different sensor/magnet arrangements apply to regular vs irregular inter-floor distances, and to speeds below or above 1 m/s.
• Short storeys and inverted-slowdown cases have dedicated layouts.
• Run the shaft Autolearning after the magnets are set.

Before putting the lift into service:

1. Check the safety chain and the CS / EXC LEDs.
2. Set the number of stops, door type and manoeuvre, then run the shaft Autolearning.
3. Verify levelling at every floor and the door open/close timing.
4. Perform the upper and lower override tests and the emergency-return (ARD) test.
5. On a blocking fault, hold RESET for 5 seconds.

The controller implements the EN 81-20:2020 / EN 81-50:2020 safety functions.

• Fit the required safety components (car-access and pit-access contacts, monitoring contacts) and enable the function by parameter.
• Run the prescribed tests and operation checks.
• Errors generated by the security contacts (per clause 5.12.1.8/.9) are reported on the mainboard display — see the mainboard diagnostics for the fault codes.
