APPLICATIONS

Variable Boost

1538 VB Time

Variable Boost Time

Sets the time delay for which the variable voltage boost trigger becomes active

following a drive start.

This parameter begins counting down when the drive enters the run state. Valid trigger

conditions may only be met in the time following the expiration of [VB Time] to cause a

trigger event. This time delay does not affect the trigger condition associated with

P1540 [VB Maximum].

RW Real

1539 VB Minimum

Variable Boost Minimum

Sets the minimum boost voltage level for the variable boost voltage function.

If P1537 [VB Voltage] reaches P1540 [VB Maximum] voltage or one of the variable boost

voltage trigger events occurs then P1537 [VB Voltage] decelerates at the rate

corresponding to P1542 [VB Decel Rate].

RW Real

1540 VB Maximum

Variable Boost Maximum

Sets the maximum boost voltage level for the variable boost voltage function.

If P1537 [VB Voltage] reaches [VB Maximum] voltage then [VB Voltage] decelerates at

the rate corresponding to P1542 [VB Decel Rate].

1541 VB Accel Rate

Variable Boost Acceleration Rate

Sets the rate of acceleration of P1537 [VB Voltage] for the variable boost voltage

function.

1542 VB Decel Rate

Variable Boost Deceleration Rate

Sets the rate of deceleration of P1537 [VB Voltage] for the variable boost voltage

function following a trigger event.

RW Real

1544 VB Min Freq

Variable Boost Minimum Frequency

Sets the frequency reference trigger level for the variable boost voltage function.

P1536 [VB Status] Bit 5 “Freq Trigger” is set to 1 when P1 [Output Frequency] falls below

[VB Min Freq].

To enable this threshold and trigger event: Set P1535 [VB Config] Bit 0 “VB Enable” to 1

and Bit 4 “Minimum Freq” to 1.

1545 VB Flux Thresh

Variable Boost Flux Threshold

Sets the flux current trigger level for the variable boost voltage function.

P1536 [VB Status] Bit 4 “Flux Trigger” is set to 1 when P1547 [VB Filt Flux Cur] exceeds

[VB Flux Thresh].

To enable this threshold and trigger event: Set P1535 [VB Config] Bit 0 “VB Enable” to 1

and Bit 3 “Flux Level” to 1.

1546 VB Flux Lag Freq

Variable Boost Flux Lag Frequency

Sets the lag (cutoff) frequency of the P6 [Flux Cur Fdbk] low pass filter.

The output of this filter is displayed in P1547 [VB Filt Flux Cur].
