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 respec-
tively, the motor runs clockwise when seen from the front.
NB!
This parameter cannot be adjusted while the mo-
tor is running
[0] Clockwise The motor shaft rotates in clockwise direction. This setting pre-
vents 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 set-
ting 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 min-
imum 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.
