4-** Limits and Warnings
Parameter group for configuring limits and warnings.
4-1* Motor Limits
Define torque, current and speed limits for the motor, and the reaction of the frequency converter when the
limits are exceeded.
A limit may generate a message on the display. A warning will always generate a message on the display or on
the fieldbus. A monitoring function may initiate a warning or a trip, upon which the frequency converter will
stop and generate an alarm message.
4-10 Motor Speed Direction
Option: Function:
Selects the motor speed direction required.
Use this parameter to prevent unwanted reversing.
[0] Clockwise Only operation in clockwise direction will be allowed.
[2] * Both directions Operation in both clockwise and anti-clockwise direction will be allowed.

par.4-13
Motor Speed High Limit [RPM].
4-12 Motor Speed Low Limit [Hz]
Range: Function:
0 Hz* [0 - par. 4-14 Hz] Enter the minimum limit for motor speed. The Motor Speed Low Limit
can be set to correspond to the minimum output frequency of the motor
shaft. The Speed Low Limit must not exceed the setting in par.4-14
Motor
Speed High Limit [Hz].
4-13 Motor Speed High Limit [RPM]
Range: Function:
1500.
RPM*
[par. 4-11 - 60000. RPM] Enter the maximum limit for motor speed. The Motor Speed High Limit
can be set to correspond to the manufacturer’s maximum rated motor.
The Motor Speed High Limit must exceed the setting in par.4-11
Motor
Speed Low Limit [RPM]. Only par.4-11 Motor Speed Low Limit [RPM] or
par.4-12
Motor Speed Low Limit [Hz] will be displayed depending on
other parameters in the Main Menu and depending on default settings
dependant on global location.
NOTE: Max. output frequency cannot exceed 10% of the inverter switching frequency (par.14-01
Switching Fre-
quency).
NOTE: Any changes in par.4-13
Motor Speed High Limit [RPM] will reset the value in par.4-53 Warning Speed
High to the same value as set in par.4-13 Motor Speed High Limit [RPM].
