335 Abs OverSpd Lim
Sets an incremental speed above Par 76 [Fwd Speed Limit] and below Par 75 [Rev Speed Limit] that is allowable
before the drive indicates its speed is out of range.

RW Real
336 Motor OL Factor
Sets the minimum level of current that causes a motor overload trip under continuous operation. Current levels
below this value will not result in an overload trip. For example, a service factor of 1.15 implies continuous
operation up to 115% of nameplate motor current.

RW Real
337 Mtr I2T Curr Min
Sets the minimum current threshold for the motor overload (I
2
T) function. The value indicates minimum current
at the minimum speed, Par 338 [Mtr I2T Spd Min], and these are the first current/speed breakpoint. From this
point the current threshold is linear to the value specified by Par 336 [Motor OL Factor].
Default:
Min Max:
Units:

0.0500/2.0000
P. U .
RW Real
338 Mtr I2T Spd Min
Sets the minimum speed for the motor overload (I
2
T) function. The value indicates minimum speed below the
minimum current threshold Par
337 [Mtr I2T Curr Min], and these are the first current/speed breakpoint. From this
point the current threshold is linear to the value specified by the motor service factor Par
336 [Motor OL Factor].
Set this parameter to the minimum value for the motor overload trip to vary in time at low speeds. For more
information, please see Motor Overload
on page 164.

RW Real
339 Mtr I2T Calibrat
Sets the current calibration level for the motor overload (I
2
T) function. The value indicates the current level that
the drive will fault at this current in 60 seconds.
Default:
Min/Max:
Units:
2.0000
1.1000/4.0000
P. U .
RW Real
340 Mtr I2T Trp ThrH
Displays the trip threshold current for the motor overload (I
2
T) function. The value depends on the motor speed,
and is calculated from the minimum current Par
337 [Mtr I2T Curr Min], the minimum speed Par 338 [Mtr I2T Spd
Min] and the motor service factor Par 336 [Motor OL Factor].
Default:
Min/Max:
Units:
1.1500
0.0500/2.0000
P. U .
RO Real
341 Mtr I2T Count
The accumulator for Motor Overload detection (Motor I
2
T function). When the motor runs at the over rated motor
current, the accumulator starts counting up. If the motor runs at below rated motor current, the accumulator
counts down. If the value of this parameter exceeds 0.5, the “Motor OLoad Pend” alarm (fault 12) occurs. If the
value of this parameter exceeds 1.0, the “Motor OLoad Trip” fault (fault 11) occurs. The value of this parameter is
saved in non-volatile memory after power-down if Par
153 [Control Options], bit 20 “Motor OL Ret” is on. Toggling
bit 20 of Par 153 [Control Options] clears the value of this parameter.
Note: This parameter was added for firmware version 3.001.
