[Compensation]
Enables/disables correction options.
Option Descriptions
Reflect Wave
Disables reflected wave overvoltage protection for long cable
lengths. (typically enabled).
Enable Jerk
In non-FVC Vector modes, disabling jerk removes a short
S-curve at the start of the accel/decel ramp.
Ixo AutoCalc
Not functional – reserved for future enhancements.
Xsistor Diag
Disables power transistor power diagnostic tests which run at
each start command.
Rs Adapt
FVC w/Encoder Only - Disabling may improve torque regulation
at lower speeds (typically not needed).
Mtr Lead Rev
Reverses the phase rotation of the applied voltage, effectively
reversing the motor leads.
PWM Freq Lock Keeps the PWM frequency from decreasing to 2 kHz at low
operating frequencies in FVC Vector mode without encoder.
057
[Flux Up Mode]
Auto = Flux is established for a calculated
time period based on motor nameplate
data. [Flux Up Time] is not used.
Manual = 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.

059
[SV Boost Filter]
Sets the amount of filtering used to boost
voltage during Sensorless Vector and
FVC Vector (encoderless) operation.
