Motor Control
[IR Drop Volts]
Used in “Economize” & “Sens Vector” modes - Sets the
valueof voltsdropped across the resistanceof the motor
stator. If set to zero, the drive will use an internal value
based on motor F.L.A. and rated voltage. Some motors
(i.e. 6 pole, special, etc.) may be particularly sensitive to
the adjustment of this parameter. Refer to the tuning
procedure in Chapter 6 for further information.
Parameter Number 194
Parameter Type Read and Write
Display Units / Drive Units 0.1 Volt / 4096 = Drive Rated Volts
Factory Default Based on Drive Size & Type
Minimum Value 0.0 Volts
Maximum Value 25% of Drive Rated Volts
[Flux Up Time]
Setstheamountoftimethedrivewillusetotryandachieve
fullmotorstatorflux.WhenaStartcommandisissued,DC
current at current limit level is used to build stator flux
before accelerating.
Parameter Number 200
Parameter Type Read and Write
Display Units / Drive Units 0.1 Sec / Sec x 10
Factory Default 0.0 Sec
Minimum Value 0.0 Sec
Maximum Value 5.0 Sec
[Start Boost]
This parameter sets the DC start boost level for
acceleration when[Control Select] isset to “Fixed Boost”
or “Full Custom.”
Parameter Number 48
Parameter Type Read and Write
Display Units / Drive Units 1 Volt / 4096 = Drive Rtd Volts
Factory Default 0 Volts
Minimum Value 0 Volts
Maximum Value 9.5% of Drive Rated Voltage
[Run Boost]
ThisparametersetstheDCboostlevelforconstantspeed
level when[Control Select] is setto “FixedBoost” or “Full
Custom.”
Parameter Number 83
Parameter Type Read and Write
Display Units / Drive Units 1 Volt / 4096 = Drive Rtd Volts
Factory Default 0 Volts
Minimum Value 0 Volts
Maximum Value 9.5% of Drive Rated Voltage
[Boost Slope]
Sets the slope of thevolts/Hertz curve from [Start Boost]
and [Run Boost] to the intersect point (see Fixed boost
diagram on previous page) when [Control Select] equals
fixed boost. The intersect is determined by multiplying:
Run Boost x Boost Slope = A
Start Boost x Boost Slope = B.
Parameter Number 169
Parameter Type Read and Write
Display Units / Drive Units None
Factory Default 1.5
Minimum Value 1.0
Maximum Value 8.0
[Break Voltage]
Setsthevoltagethedrivewilloutputat[BreakFrequency].
Combined with [Break Frequency], this parameter
determines the volts-per-Hertz pattern between 0 and
[Break Frequency].
Parameter Number 50
Parameter Type Read and Write
Display Units / Drive Units 1 Volt / 4096 = Drive Rtd Volts
Factory Default 25% of Drive Rated Voltage
Minimum Value 0 Volts
Maximum Value 50% of Drive Rated Voltage
[Break Frequency]
This parameter sets a midpoint frequency on a custom
volts-per-Hertzcurve.Combinedwith[BreakVoltage],this
valuedetermines thevolts-per-Hertz ratio between0and
[Break Frequency].
Parameter Number 49
Parameter Type Read and Write
Display Units / Drive Units 1 Hertz / Hertz x 10
Factory Default 25% of [Maximum Freq]
Minimum Value 0 Hz
Maximum Value 120 Hz
