335 Abs OverSpd Lim
Sets an incrmental speed above parameter 31 [Fwd Speed
Limit] and below parameter 30 [Rev Speed Limit] that is
allowable before the drive indicates its speed is out of range.

336 Service 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.

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, parameter 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 parameter
336 [Service Factor].
