[A134]
(Stall Fault Time
iii
) This parameter sets the
time that the drive can be at or above the
STALL TEST LVL(A1), before the drive
declares an STALL TEST FAULT. In order
for a STALL TEST FAULT to occur, it must
be enabled by the STALL TEST ENA (C1)
parameter.

[A135]
(Slip Compensation Time Constant
iii
) Slip
compensation filter time constant. Adjusted
for slip compensation response and stability.
By increasing the value of the parameter,
the response time of the slip compensation
function will become slower. Reducing the
parameter to a lower value makes the slip
compensation function respond more
quickly. Note: Setting the parameter too
low may result in unstable motor operation
or setting the parameter too high will result
in very poor response.
NOTE: it is usually best to leave this
parameter set at default of 1.5 seconds.
Slip compensation allows an open-loop drive
to maintain constant motor speed regardless
of loading. The function adjusts the drive’s
output frequency (and output voltage) to
compensate for motor slip as the motor load
is increased. The compensation is based on
the motor rated speed, frequency and
calculated motor torque, therefore a valid
value must be entered for the Rated Motor
Speed (RATED MTR SPEED(A5))

Slip Comp
Gain
iii
[A136]
(Slip Compensation Gain
iii
) Multiplier of
motor rated slip at rated torque. Setting the
parameter to 1.00 compensates the drive
output frequency by rated slip at rated
torque. Setting the Slip Compensation Gain
to 0.00 disables the slip compensation
function.
NOTE: it is usually best to leave this
parameter set at the default of 1.0.
