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.
NOTE
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 1-00 Configu-
ration Mode is set to close loop control, 4-10
Motor Speed Direction will be automatically set
to clockwise.
[1] Counter-
clockwise
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
(4-12 Motor Speed Low Limit) to Motor Speed
High Limit (4-14 Motor Speed High Limit). If
1-00 Configuration Mode is set to open loop
control, 4-10 Motor Speed Direction will be
automatically set to both direction
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.
NOTE
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.
NOTE
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 1-00
Configuration Mode 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 1-00
Configuration Mode to 1-25 Load & Motor.
