Speed Limit] that is allowable before the drive indicates its speed is out of range.

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.

Mtr I2T Curr Min
Sets the minimum current threshold for the motor overload (I
2
T) function. The value
indicates the 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 [Service Factor].

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

Mtr I2T Trp ThrH
Displays the trip threshold current for the motor overload (I

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 [Service Factor].

OL OpnLp CurrLim
Displays the current limit set by the Open Loop Inverter Overload (OL) function. This
function sets this current limit based on stator current feedback and the current ratings of
the drive - continuous and short term (three-second rating). Typically the drive will have a
sixty-second rating of 110% of continuous current and a three-second rating at 150% of
the continuous current. Under normal operating conditions, the open loop function sets
this current limit to the short term (three-second) rating. If the function detects an
overload, it lowers the limit to the continuous level. After a period of time (typically one to
three minutes), the function returns the limit to the short term rating.

OL ClsLp CurrLim
Displays the current limit set by the Closed Loop Inverter Overload (OL) function. This
function will set a current limit level based on the values in Par 358 [Iq Ref Limited], Par
313 [Heatsink Temp] and the thermal characteristics of the drive. Under normal operating
conditions, the function typically sets the limit at 250% of the continuous drive rating. If
the function determines that the power device junction temperature is approaching
maximum, it will reduce this limit to the level required to prevent additional heating of the
inverter. This level could be as low as the continuous rating of the drive. If the inverter
temperature decreases, the function will raise the limit to a higher level. Disable this
protection by setting bit 13 [OL ClsLpDsbl] of Par 153 [Control Options].
