2 EN921 - Variable Voltage w/ PI Power/Current Control
Voltage Control
[Volt Incr Time]
This value determines the time it will take the drive to ramp
from 0 Volts to [Maximum Voltage] when [Control Select]
is set to “Variable Voltage”. The rate determined by this
value and [Maximum Voltage] is linear.
Parameter Number 334
Parameter Type Read and Write
Display Units / Drive Units 0.1 Second / Seconds x 10
Factory Default 10.0 Sec
Minimum Value 0.0 Sec
Maximum Value 3600.0 Sec
[Volt Decr Time]
This value determines the time it will take the drive to ramp
from [Maximum Voltage] to 0 Volts when [Control Select]
is set to “Variable Voltage”. The rate determined by this
value and [Maximum Voltage] is linear.
Parameter Number 335
Parameter Type Read and Write
Display Units / Drive Units 0.1 Second / Seconds x 10
Factory Default 10.0 Sec
Minimum Value 0.0 Sec
Maximum Value 3600.0 Sec
[Voltage Command]
This parameter displays the commanded voltage value
from the reference specified by [Volt Select].
Parameter Number 336
Parameter Type Read Only
Display Units / Drive Units 1 Volt / 4096 = Drive Rated Volts
Factory Default None
Minimum Value 0 Volts
Maximum Value 120% Rated Drive Output Voltage
[Volt Select]
This parameter specifies which input signal will be used
as the [Volt Command] reference when [Control Select] is
set to “Variable Voltage”.
Parameter Number 337
Parameter Type Read and Write
Factory Default “Volt Preset”
Units Display Drive
“Analog In 0” 0
“Analog In 1” 1
“Analog In 2” 2
“Volt Preset” 3 Refer to [Volt Preset] Value
“Adapter 1-6” 4-9
“Volt Cmd Ref” 10 Refer to [Volt Command Ref] Value
“Voltage PI” 11 Refer to “Voltage PI” Group
[Volt Preset]
This parameter specifies the output voltage setpoint value
when [Volt Select] is set to “Volt Preset”.
Parameter Number(s) 338
Parameter Type Read and Write
Display Units / Drive Units 1 Volt / 4096 = Drive Rated Volts
Factory Default 0 Volts
Minimum Value 0 Volts
Maximum Value 120% Drive Rated Volts
[Volt Trim Select]
This parameter specifies which input signal will be used to
trim (increase/decrease) the [Volt Command] reference.
Volt trim is only active when [Volt Trim%] is set to a non-zero
value.
Parameter Number 339
Parameter Type Read and Write
Factory Default “Analog In 1”
Units Display Drive
“Analog In 0” 0
“Analog In 1” 1
“Analog In 2” 2
“Volt Preset” 3 Refer to [Volt Preset] Value
