Torq Boost
Time
iii
[A137]
(Torque Boost Time Constant
iii
) This
parameter is the torque boost filter time
constant. Adjusted for torque compensation
response and stability. Increasing the value
of the parameter, decreases response.
Reducing the parameter to a lower value
increases response.
NOTE: it is usually best to leave this
parameter set at the default of 0.5 seconds.
Torque compensation automatically boosts
the drive’s output voltage, in excess of the
programmed V/Hz pattern, as the load
demand increases. Torque compensation
counters the voltage drop in the motor stator
resistance. This function has the greatest
effect at low speeds improving load
response. When using torque compensation,
a valid value must be entered for the motor’s
no-load current (% NO LOAD CURR(A5))

Torq Boost
Gain
iii
[A138]
(Torque Boost Gain
iii
) This gain controls the
differential term in the voltage boost
function. This affects the rate of response of
the torque boost. Setting the Torque Boost
Gain to 0.00 disables the torque boost
function.
NOTE: this function is defaulted off (TORQ
BOOSTGAIN=0.0). If adjustments need to
be made follow the guidelines listed in the
“Performance Adjustments” on page181.
