At this point it is necessary to have a feel for how fast the motor is required to move in the application. If you don’t know what the

application max speed is likely to be at this stage then set this to approximately 75% of the max motor speed. If the application

actually requires a speed in excess of the value typed here then it will not be able to attain the demanded speed and a drive over-

speed trip error will be created. If the application max speed is changed later (e.g. via the “Operating Mode” pages within

Workbench) then it will be necessary to retune the drive’s speed and position loops.

Be aware that the maximum speed is limited both by the available bus voltage (approximately 1.41 times the AC supply voltage to

the drive) and the motor’s physical maximum speed, therefore the speed entered at this point cannot exceed either of these two

values which are displayed for reference (if the Max Theoretical Speed is displaying 0 or a low value, check the AC supply to the

drive is present).

For applications that are designed to run at slower speeds it is advisable that the Application Max Speed is reduced to maximise the

speed resolution available, this will improve speed accuracy at lower speeds. But always set this parameter to a value slightly in

excess of the maximum required to avoid unwanted errors. It is best not to set this below 500 RPM. For very slow running

applications it is advisable to select a motor with high resolution feedback (e.g. Endat, SSI or BISS).

The position, velocity and acceleration user units are set here. These are used mainly during the commissioning wizard (i.e. they set

the user unit for all commands issued locally on the drive). Once the Nextmove e100 is used to command motion it will use its own

set of scalefactors for this axis (set via the Mint program onboard the Nextmove e100).

In summary, any motion commands initiated on the drive directly (e.g. via the Workbench command window or as part of the drive’s

homing process which is always profiled by the drive itself) will use the scalefactors set on the drive.
