Software

• self optimizing operating menue
• easy diagnosis
• parameter in lift-terminology
• protection against wrong adjustment
• easy adjustment
• multi encoder
• open-loop-vector-control
• multi motor
• special digital in- and output functions like:

1. - brake control
2. - main contactor
3. - UPS function
4. - level running open doors

• speed curve with 5 independent jerks and different acceleration and deceleration for shortest floor-to-floor-times for best driving comfort and optimized passenger conveyance
• direct approach with correction input or positioning control
• self optimizing only with motor-nameplate-data and winding resistance
• speed setting via digital inputs, analog inputs, via BUS, or positioning control
• ogive function with automatic correction of decceleration-curve

Your advantages:

• Maintains constant speed in both up and down, loaded and unloaded conditions

• Good positioning, load independent, + 1 mm

• Easy adjustment, self tuning only by setting the motor-nameplate-data and measuring the winding resistance (can be measured by the inverter drive after installation)

• Digital input for brake release check

• Digital input for main contactor check (verifies the contactor is switching between each run)

• Saves installation costs

• Main contactor output to control the contactor and provide powerless switching of the contactor

• Speed-and current-regulator-values are self adjusting

• Works even with old high slip (> 10%) two speed motors

• Positioning controller still works, even when running the motor open loop, uses a position sensor in the hoistway instead.

• Output-phase check before brake opening and during the run for maximum safety

Elevator Drives:

• Encoder failure detection

• Output phase check

• Over-current detection

• Under-voltage detection

• Over-voltage detection

• Speed deviation detection

• Brake opening check

• Main contactor check

• Over speed fault

• Powerless switching of main contactors

• Speed limitation whilst inspection-, levelling- and relevelling-speed

• Healing of encoder-puls-loss and encoder-puls-excess
