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- The motor shaft rotates in counterclockwise
clockwise 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.
