Parameter Group 4-** Limits/Warnings - Danfoss VLT Flow Drive FC 111 Programming Manual

VLT® Flow Drive FC 111
Programming Guide
Table 109: Range:
Min: 0.01 s Max: 3600 s
3-81 Quick Stop Ramp Time
Default value: Configuration dependent
Conversion index: -2
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.

Min: 0.01 s Max: 3600 s

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
Conversion index: -
Select the motor speed direction(s) required. Use this parameter to prevent unwanted reversing.
Table 111: Option:
[0] Clockwise
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
Conversion index: -1
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].
Table 112: Range:
Min: 0 Hz
4-14 Motor Speed High Limit [Hz]
Default value: 100 Hz
Conversion index: -1
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.
