4.5. Parameter Group 4: Limits/Warnings
4.5.1. 4-** Motor Limits
Parameter group for configuring limits and warning.
4.5.2. 4-1* Motor Limits
Use these parameters for defining the speed, torque and current working range for the motor.
4-10 Motor Speed Direction
Option: 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
[0] Clockwise 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 Process Closed Loop [3] this parameter must always be set to
Clockwise .
[1] Counterclockwise The motor shaft rotates in counterclockwise direction. This setting prevents the motor from running in clockwise
direction.
[2]
*
Both 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).
4-12 Motor Speed Low Limit
Range: Function:
0.0 Hz * [0.0 - 400.0 Hz]
Set the
Minimum Motor Speed Limit 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.
4-14 Motor Speed High Limit
Range: Function:
65.0 Hz * [0.0 - 400.0 Hz]
Set the
Maximum Motor Speed 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.
4-16 Torque Limit in Motor Mode
Range: Function:
150 % * [0 - 400%]
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
Load & Motor .
4-17 Torque Limit in Generator Mode
Range: Function:
100 % * [0 - 400%]
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
Load & Motor .
