This parameter sets gain multiplier
for the OV regulator gain (P1-02)
based on output frequency. See

This parameter sets the amount of
time that the drive will revert to a
reduced speed after an Overheat
Pre-alarm occurs. See section 5.5
for details.

Speed Reduction
OH Spd Reduce
This parameter sets the multiplier
used to reduce the frequency
reference after an Overheat Pre-
alarm occurs. See section 5.5 for
details.

Belt Break Detection
Belt Break Det.
This parameter configures the Belt
Break Detection function. If the
drive’s soft starter is at maximum
output frequency (E1-04) for more
than 30 seconds, a belt-break fault
(B-BRK) will occur. See section 5.4
for details.

Start Torque
This parameter determines the
forward and reverse motoring
torque limits after a run command
is received, but before the torque
start timer (P3-02) expires.
Overwrites L7-01 and L7-02.

Torque Limit During
Start Ramp Time
Torq Lim Ramp Tm
This parameter sets the time
required to ramp the torque limit
100%. This determines the rate at
which the torque limits will return to
the L7-01 and L7-02 values at the
end of the starting torque time (P3-
02).

*1: Access Level (A1-01): Q = “Quick Start”, A = “Advanced”, F = “Factory”. V/F and Open Loop Vector only.
*2: Making large changes in these settings while the drive is running can result in large and very rapid changes in
the output frequency. Change these parameters in small increments only.
