Flux is established for [Flux Up Time] before
acceleration.

058 [Flux Up Time]
Sets the amount of time the drive will use to try
and achieve full motor stator flux. When a Start
command is issued, DC current at current limit
level is used to build stator flux before
accelerating. This will occur unless [Rated Amps]
is less than [Motor NP FLA], then only 81% of
drive rated current is used.

061 [Autotune]

setting [IR Voltage Drop], and [Flux Current Ref].

“Ready” (0) = Parameter returns to this setting following a “Static Tune” or “Rotate Tune.” It also
permits manually setting [IR Voltage Drop], [Ixo 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], [Break Voltage] and [Break
Frequency] in all modes. A start command is required within 20 seconds 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. Used when motor cannot be rotated.
“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] and [Start Boost]. 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.
“Calculate” (3) = This setting uses motor nameplate data to automatically set [IR Voltage Drop],
[Flux Current Ref] and [Slip RPM @ FLA].

motor stator at rated motor current.

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.
