No. Parameter Name and Description
061 [Autotune]
Provides a manual or automatic method
for setting [IR Voltage Drop] and [Flux
Current Ref], which affect sensorless
vector performance. Valid only when
[Torque Perf Mode] is set to "Sensrls Vect"
or "SV Economize."
"Ready" (0) = Parameter returns to this setting following a "Static Tune" or "Rotate
Tune." It also permits manually setting [IR Voltage Drop] and [Flux Current Ref].
"Static Tune" (1) = A temporary command that initiates a non-rotational motor
stator resistance test for the best possible automatic setting of [IR Voltage Drop].
A start command is required following initiation of this setting. The parameter
returns to "Ready" (0) following the test, at which time another start transition is
required operate the drive in normal mode. Used when motor cannot be
uncoupled from the load.
"Rotate Tune" (2) = A temporary command that initiates a "Static Tune" followed by
a rotational test for the best possible automatic setting of [Flux Current Ref]. A
start command is required following initiation of this setting. The parameter
returns to "Ready" (0) following the test, at which time another start transition is
required to operate the drive in normal mode. Important: Used when motor is
uncoupled from the load. Results may not be valid if a load is coupled to the motor
during this procedure.
ATTENTION: Rotation of the motor in an undesired direction
can occur during this procedure. To guard against possible injury
!
and/or equipment damage, it is recommended that the motor be
disconnected from the load before proceeding.
"Calculate" (3) = This setting uses motor nameplate data to automatically set [IR
Voltage Drop] and [Flux Current Ref].
062 [IR Voltage Drop]
Value of volts dropped across the
resistance of the motor stator.
Used only when [Torque Perf Mode]
to "Sensrls Vect" or "SV Economize."
063 [Flux Current Ref]
32 Value of amps for full motor flux.
Used only when [Torque Perf Mode]
to "Sensrls Vect" or "SV Economize."
069 [Start/Acc Boost]
Sets the voltage boost level for starting
and acceleration when "Custom V/Hz"
mode is selected.
Refer to parameter 083 [Overspeed Limit].
070 [Run Boost]
Sets the boost level for steady state or
deceleration when "Fan/Pmp V/Hz" or
"Custom V/Hz" modes are selected.
Refer to parameter 083 [Overspeed Limit].
