Smallest and most powerful AC drive in its class
A
Moeller Electric product story
Edited by the Engineeringtalk editorial team
Dec 21, 2000
The new Optidrive from Moeller Electric is not only one of the industry's smallest and most powerful AC drives in its class but also by far the most user-friendly.
The new Optidrive from Moeller Electric is not only one of the industry's smallest most powerful AC drives in its class but also by far the most user-friendly.
Spanning a 0.3kW to 90kW power range, Optidrive is available in both single and three-phase formats in five case sizes, providing users with the highest levels of performance and flexibility at market competitive prices.
Ready-to-run, the new drives have three programmable digital inputs, an analogue input that is selectable for volts or amps, a programmable relay output, and a programmable analogue output.
All that is needed for basic pump and fan operation is the setting of five basic parameters from the 14 standard that are available.
Optidrive has four pre-set speeds and an auto start function.
Other features include skip frequencies, spinning start, silent running in 32kHz mode and mains dip ride through.
AC drives are notoriously complicated to set-up, so user-friendliness was high on the list of priorities for the designers of Optidrive.
A 'quick' set-up menu using only the 14 standard parameters, with plain English descriptions, allows the user to quickly configure the Optidrive.
An extended menu with a further 26 parameters is available for more advanced set-ups.
Drive parameters can be modified via the unit's five-button front panel or using the unique and innovative Optiwand.
This is a handheld remote control unit that employs infrared technology to communicate with the drive and/or a PC.
The Optiwand has the same five-button layout as the drive and can store up to 63 complete Optidrive settings.
Everything that can be done via the drive front-panel can also be done via the Optiwand, then subsequently 'downloaded ' to the Optidrive.
This greatly simplifies changing the drive settings once the drive is in-situ, given that drives can often be located in cramped not easily accessible places.
For example: parameters can be downloaded from the drive to the Optiwand, modified, 'reloaded' to the drive and also sent to a PC or portable for reference, archiving, or further modification.
The drive package comes with full PC software support.
Using Optiwand, several drives with the same set-up can be very quickly configured, it taking less than 0.5s to transfer the parameters from the handheld unit to each drive.
The Optiwand can also be used to quickly monitor individual parameters and, if necessary, instantly change them, e.g the drive speed.
Both the Optidrive and the Optiwand have a very high level of data integrity.
The new Optidrive fully supports International languages, so can be operated in French, German, Italian etc.
The new drives are CE marked in accordance with the Low Voltage Directive and carry IEC, UL and EN approvals.
