no: no action

rEAd: program the drive with the contents of the SmartStick

Prog: program the SmartStick with the current drive settings

boot: SmartStick becomes read only. The contents of the SmartStick will be copied to the drive every time the drive is powered up.

Before setting boot mode, the current drive settings must be stored in the SmartStick by using Prog mode, otherwise the drive will trip on C.Acc at

power-up.

Parameter cloning is initiated by pressing the MODE key on exit from parameter edit mode after Pr 28 has been set to rEAd, Prog or boot.

If parameter cloning is enabled when no SmartStick is fitted to the drive, the drive will trip on C.Acc.

The SmartStick can be used to copy parameters between drives of different ratings. Certain drive dependant parameters will be stored on the

SmartStick but will not be copied to the cloned drive.

The drive will trip on C.rtg when being written to by a cloned parameter set of a different drive rating.

The drive dependant parameters are: Pr 06 Motor rated current, Pr 08 Motor rated voltage, Pr 09 Motor power factor and Pr 37 Maximum switching

frequency.

Before the SmartStick /LogicStick is written to using Prog, the SmartStick/LogicStick will need to be inserted into the drive at power up or a reset

command performed when the drive has been powered up, otherwise will trip on C.dAt when Prog command executed.

For best motor performance, an autotune should be carried out after parameter cloning has taken place.

no: defaults are not loaded

Eur: 50Hz default parameters are loaded

USA: 60Hz default parameters are loaded

Default parameters are set by pressing the MODE key on exit from parameter edit mode after Pr 29 has been set to Eur or USA.

When default parameters have been set, the display will return to Pr 01 and Pr 10 will be reset to L1.

The drive must be in a disabled, stopped or tripped condition to allow default parameters to be set. If default parameters are set while the drive is

running, the display will flash FAIL once before changing back to no.

0: Fast ramp selected

1: Standard ramp with normal motor voltage selected

2: Standard ramp with high motor voltage selected

3: Fast ramp with high motor voltage selected

Fast ramp is linear deceleration at programmed rate, normally used when a braking resistor is fitted.

Standard ramp is controlled deceleration to prevent DC bus over-voltage trips, normally used when there is no braking resistor fitted.

If a high motor voltage mode is selected, deceleration rates can be faster for a given inertia but motor temperatures will be higher.

0: Coast to stop selected

1: Ramp to stop selected

2: Ramp to stop with 1 second DC injection braking

3: DC injection braking with detection of zero speed

4: Timed DC injection braking

See the Commander SK Advanced User Guide.

OFF: Fixed linear voltage to frequency ratio (constant torque - standard load)

: Voltage to frequency ratio dependant on load current (dynamic/variable torque/load). This gives a higher motor efficiency.
