Adj Vltg AccTime
Adjustable Voltage Acceleration Time
Sets the rate of voltage increase. The value will be the time it takes to ramp the voltage
from P1152 [Min Adj Voltage] to P36 [Maximum Voltage]. An “S” curve can be applied
to the ramp using P1150 [Adj Volt Scurve].

Adj Vltg DecTime
Adjustable Voltage Deceleration Time
Sets the rate of voltage decrease. The value will be the time it takes to ramp the voltage
from P36 [Maximum Voltage] to P1152 [Min Adj Voltage]. An “S” curve can be applied
to the ramp using P1150 [Adj Volt Scurve]. This is an independent voltage ramp
decoupled from the scalar frequency ramp P537/538 [Decel Time n] and controlled by
user selectable acceleration and deceleration ramp times.
Important: This ramp and P537/538 [Decel Time n] must ramp to zero for drive to Stop.

Adj Vltg RefMult
Adjustable Voltage Reference Multiplier
Scales the selected reference voltage by a percentage where 100% equals the reference
command. If the reference command equals 100V and P1149 equals 100% then the
total output voltage equals 100V + 100V = 200V.

Adj Vltg Scurve
Adjustable Voltage S Curve
Sets the percentage of acceleration time or deceleration time to be applied to the
voltage ramp as “S” curve. Time is added 1/2 at the beginning and 1/2 at the end. A
value of zero disables this feature.

Adj Vltg TrimPct
Adjustable Voltage Trim Percentage
Scales the selected trim voltage by a percentage where 100% equals the trim voltage. If
the reference command equals 100V and P1151 equals 100% then the total output
voltage equals 100V + 100V = 200V.
Analog In 1 and 2 are scaled separately with P1137 [Adj Vltg Trim Hi] and P1138 [Adj
Vltg Trim Lo] then P1151 sets the trim value. The sign of this value will determine if trim
is added or subtracted from the reference.
