Function:
Enter the maximum limit for motor speed. The Motor Speed High Limit
can be set to correspond to the manufacturer's recommended maximum
of the motor shaft. The Motor Speed High Limit must exceed the in par.

settings dependant on global location.
Function:
Enter the maximum torque limit for motor operation. The torque limit is
active in the speed range up to and including the rated motor speed set

Function:
Enter the maximum torque limit for generator mode operation. The tor-

Function:
Enter the current limit for motor and generator operation. To protect the
motor from reaching the stalling torque, the default setting is 1.1 x the

Function:
Enter the maximum output frequency value. par.4-19
quency specifies the absolute limit on the frequency converter output
frequency for improved safety in applications where accidental over-
speeding must be avoided. This absolute limit applies to all configura-
tions and is independent of the setting in par.1-00
This parameter cannot be adjusted while the motor is running.
