Torq Attributes
056 [Compensation]
Enables/disables correction options.
Option Descriptions:
• Reflect Wave – Provides 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 – Power transistor power diagnostic tests run at each start command.
• Rs Adapt – only FVC w/Encoder – Disabling can improve torque regulation at lower
speeds (typically not needed).
• PWM Freq Lock – Keeps the PWM frequency from decreasing to 2 kHz at low operating
frequencies in FVC Vector mode without encoder.
• DigIn DatLog – Enables logic functions that can be applied to parameter 411 [DigIn
DataLogic] and the specified digital input.

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 uses 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.
