Full support is provided for a both a rotating and static autotune. There is support for a wide range of position feedback devices from the incremental

encoder to high resolution SinCos encoders along with a simulated encoder output as standard onboard the drive.

The E300 Advanced Elevator drive also has TuV Nord approval to EN81 for a zero output motor contactor solution using the drives Safe Torque Off

(STO), Drive enable input.

Profile

The default operating profile for the E300 Advanced Elevator drive is Creep to floor mode. Optimization of the profile is possible through the separate

acceleration and deceleration rates along with multiple jerks. Variable speed and current control loop gains are available for the start, travel and stop.

The E300 Advanced Elevator drive additionally offers enhanced profile control:

•

Direct to floor mode - decelerates the elevator car directly to the floor following a signal to stop, with no creep speed.

•

Peak curve operation - profile peak speed and stopping distance controlled regardless of when the signal to stop is given, optimizing travel time.

•

Floor sensor correction - using a floor sensor / limit switch to compensate for rope slip, rope stretch and other mechanical offsets.

•

Position controlled short floor operation.

An optional external load cell compensation input can be connected to the drive where required.

Parallel interface

The E300 Advanced Elevator drive and control software can support either digital only parallel interfaces (binary or priority speed selection) or digital

parallel interfaces with an analog speed reference. The drive has brake control set-up configured as default with the option of selecting the additional

output motor contactor control.

Programming, monitoring

The E300 Advanced Elevator drive has a standard Keypad which allows set-up and optimization of the drive along with monitoring of parameters.

An NV Media Card can be used which allows drive parameters to be uploaded and downloaded. The NV Media Card can also be used to back up the

drive parameter set. The NV Media Card support is via a SMARTCARD or SD card Adaptor and SD card.

The Elevator Connect PC tool allows programming, uploading and downloading of drive parameter sets along with monitoring the E300 Advanced

Elevator drive during operation and optimization. The Elevator Connect PC tool is free of charge and can be downloaded from

www.controltechniques.com.

Communications

The E300 Advanced Elevator drive has RS485 serial communications by default. This supports communications to the Elevator controller, PC tools

and Firmware programming. Additional communications protocols are supported via SI option modules.
