MOTOR CONTROL
Torq Attributes
053 [Motor Cntl Sel]
Sets the method of motor control used in the
drive.
When “Adj Voltage” is selected, voltage control is
independent from frequency control. The voltage
and frequency components have independent
references and accel/decel rates. Typical
applications include non-motor loads or power
supplies.
Important: “FVC Vector” mode requires
autotuning of the motor. Being coupled to the
load will determine inertia (preferably lightly-
loaded). Total Inertia (parameter 450) will have
to be estimated if uncoupled for tuning of the
speed loop or separately adjust Ki and Kp
(parameters 445 & 446).

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 “0” disables power transistor power diagnostic tests which run at each start
command. “1” enables transistor diagnostic tests.
Rs Adapt FVC w/Encoder Only - Disabling can 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. Note: This bit is reset to “0” when parameters are reset to
factory defaults.
PWM Freq Lock Keeps the PWM frequency from decreasing to 2 kHz at low operating
frequencies in FVC Vector mode without encoder.
DigIn DatLog Enable [DigIn DataLogic], parameter 411.
NoSyncPWM Disables synchronous PWM.
EncFiltStop In FVC Vector mode only, sets the encoder filter based on parameter 416 -
[Fdbk Filter Sel] to detect when the drive is at zero speed during the stop
sequence.
File Group No.
