Parameters: Limits/Warnings

"
4-1* Motor Limits
"
Define torque, current and speed limits for the motor.
4-10 Motor Speed Direction
Option:
*
Clockwise
Counter clockwise
Both directions
Function:
When par. 1-00 is set to Process this parameter
is set to Clockwise [0] as default.
4-11 Motor Speed Low Limit [RPM]
Range:
0 - par. 4-13 RPM
Function:
It is possible to choose to have the Minimum
Motor Speed Limit correspond to the minimum
motor speed. Minimum speed cannot exceed
the maximum speed in par. 4-13.
4-13 Motor Speed High Limit [RPM]
Range:
Par. 4-11 - Variable Limit RPM
Function:
You can choose to have the maximum motor speed
correspond to the highest motor speed.
NB!:
The output frequency value of the
frequency converter can never
be a value higher than 1/10 of
the switching frequency.
4-16 Torque Limit Motor Mode
Range:
0.0 - Variable Limit %
Function:
Sets the torque limit for motor operation. The
torque limit is active in the speed range up to
the rated motor speed (par. 1-25). To protect
the motor from reaching the stalling torque, the
default setting is 1.6 x the rated motor torque
(calculated value). If a setting in par. 1-00 to
par. 1-26 is changed, par. 4-16 to 4-18 are not
automatically reset to the default settings.

Changing par. 4-16 Torque Limit Motor
Mode when par. 1-00 is set to Speed
open loop [0], par. 1-66 Min Current
at Low Speed is automatically readjusted.
4-17 Torque Limit Generator Mode
0RPM
Range:
0.0 - Variable Limit %
Function:
Sets the torque limit for generator mode operation.
The torque limit is active in the speed range up to
the rated motor speed (par. 1-25). See illustration
for par. 4-16 as well as par. 14-25 for further details.
4-18 Current Limit
Range:
0.0 - Variable Limit %
Function:
Sets the current limit for motor operation. To
protect the motor from reaching the stalling torque,
the default setting is 1.6 x the rated motor torque
(calculated value). If a setting in par. 1-00 to par.
1-26 is changed, par. 4-16 to par. 4-18 are not
automatically reset to the default settings.
4-19 Max Output Frequency
Range:
0.0 - 1000.0 Hz
Function:
Provides a final limit on the drive output frequency
for improved safety in applications where you
want to avoid accidental overspeeding. This
limit is final in all configurations (independent
of the setting in par. 1-00).
Par. 4-19 cannot be adjusted while the
motor is running.
