Table 109: Range:
Min: 0.01 s
Max: 3600 s
Default value: Configuration dependent
3-81 Quick Stop Ramp Time
Default value: Configuration dependent
Parameter type: Range
2-setup: 1 setup
Conversion index: -2
Data type: u_int32
Change during operation: True
Enter the quick stop ramp time from the
parameter 1-23 Motor Frequency
to 0 Hz. During ramping, no overvoltage may occur in the
inverter, nor may the generated current exceed the limit in
parameter 4-18 Current Limit
. Quick stop is activated with a signal on a
selected digital input or via the serial communication port.

4.6 Parameter Group 4-** Limits/Warnings
4.6.1 4-1* Motor Limits
Define current and speed limits for the motor, and the reaction of the drive when the limits are exceeded.
4-10 Motor Speed Direction
Default value: [2] Both directions
Parameter type: Option
2-setup: All setups
Conversion index: -
Data type: u_int8
Change during operation: False
Select the motor speed direction(s) required. Use this parameter to prevent unwanted reversing.
Table 111: Option:
[0]
Clockwise
N O T I C E
The setting in
parameter 4-10 Motor Speed Direction
has impact on
parameter 1-73 Flying Start
.
Only operation in clockwise direction is allowed.
[2]
Both directions
Operation in both clockwise and counterclockwise directions is allowed.
4-12 Motor Speed Low Limit [Hz]
Default value: 0 Hz
Parameter type: Range
2-setup: All setups
Conversion index: -1
Data type: u_int16
Change during operation: True
Enter the minimum limit for motor speed. The motor speed low limit can be set to correspond to the minimum output frequency of
the motor shaft. The speed low limit must not exceed the setting in
parameter 4-14 Motor Speed High Limit [Hz]
.

4-14 Motor Speed High Limit [Hz]
Default value: 100 Hz
Parameter type: Range
2-setup: All setups
Conversion index: -1
Data type: u_int16
Change during operation: True
Enter the maximum limit for motor speed. It can be set to match the recommended maximum motor speed. The motor speed high
limit must exceed the value in
parameter 4-12 Motor Speed Low Limit [Hz]
. Motor speed high limit cannot be set higher than
parame-
ter 4-19 Max Output Frequency
.
