2.1 E300 Elevator drive
E300 Elevator drive features
• Universal high performance drive for asynchronous induction motors and synchronous permanent magnet motors.
• Flexibility with speed and position measurement, supporting multiple devices and all common interfaces.
• Analog and digital I/O with Safe Torque Off (STO) input.
• Local and Remote keypad options.
• NV Media Card for parameter copying and data storage.
Configuration
The E300 Elevator drive can operate in either Open loop or RFC-A mode with asynchronous induction motors for geared Elevator applications or in
RFC-S mode with synchronous permanent magnet motors for gearless Elevator applications. The default operating mode for the E300 Elevator drive
is RFC-S mode with this targeted at gearless Elevator applications using PM synchronous motors.
Full support is provided for 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 Elevator drive also has TuV Nord approval to EN81 for:
1. Zero Output Motor Contact Solution using the drives safe torque off (STO).
2. Brake Contact Monitoring support to meet the requirements of unintended car movement (UCM) to EN81 where up to 4 motor brakes are used.
Profile
The default operating profile for the E300 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 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 Elevator drive and control software can support either:
1. Digital only parallel interfaces (binary or priority speed selection)
2. Digital parallel interfaces with Analog speed reference.
3. Control word (Modbus RTU)
4. DCP control (SI-DCP option).
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 Elevator drive has a KI-Remote Keypad RTC 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 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 Elevator drive has RS485 serial communications by default. This supports communications to the Elevator controller, PC tools and
Firmware programming.
