Function:
If terminals 96, 97 and 98 are connected to U, V and W respectively, the motor runs clockwise when seen from
the front.
NB!
This parameter cannot be adjusted while the motor is running
The motor shaft rotates in clockwise direction. This setting prevents the motor from running in counterclockwise
direction.
If par. 1-00 Configuration mode has been set to
Clockwise
.
The motor shaft rotates in counterclockwise direction. This setting prevents the motor from running in clockwise
direction.
With this setting the motor can run in both directions. However, the output frequency is limited to the range:
Motor Speed Low Limit (par. 4-12) to Motor Speed High Limit (par. 4-14).
Function:
Minimum Motor Speed Limit
Set the corresponding to the minimum output frequency of the motor shaft.
NB!
As the minimum output frequency is an absolute value, it cannot be deviated from.
Function:
Maximum Motor Speed
Set the corresponding to the maximum output frequency of the motor shaft.
NB!
As the maximum output frequency is an absolute value, it cannot be deviated from.
Function:
Set the torque limit for motor operation.
The setting is not automatically reset to default when changing settings in par. 1-00 to 1-25
Function:
Set the torque limit for generator mode operation.
The setting is not automatically reset to default when changing settings in par. 1-00 to 1-25
