Danfoss VLT AutomationDrive FC 301 Programming Guide

Enter the delay required from activation of the digital potentiometer function until the drive starts to ramp the reference. With a
delay of 0 ms, the reference starts to ramp when increase/decrease is activated. See also parameter 3-91 Ramp Time.
5.5 Parameter Group 4-** Limits/Warnings
5.5.1 4-1* Motor Limits
Define torque, current, and speed limits for the motor, and the reaction of the drive when the limits are exceeded. A limit may gen-
erate a message in the display. A warning always generates a message in the display or on the fieldbus. A monitoring function may
initiate a warning or a trip, after which the drive stops and generates an alarm message.
Parameter 4-10 Motor Speed Direction

Change during operation: False
N O T I C E
This parameter cannot be adjusted while the motor is running.
Select the motor speed directions required. Use this parameter to prevent unwanted reversing. When parameter 1-00 Configuration
Mode is set to [3] Process, parameter 4-10 Motor Speed Direction is set to [0] Clockwise as default. The setting in parameter 4-10 Motor
Speed Direction does not limit options for setting parameter 4-13 Motor Speed High Limit [RPM].
Option
Name
Description
[0]
Clockwise
The reference is set to CW rotation. Reversing input (default terminal 19) must be open.
[1]
Counterclock-
wise
The reference is set to CCW rotation. Reversing input (default terminal 19) must be closed. If revers-
ing is required with reverse input open, the motor direction can be changed by parameter 1-06
Clockwise Direction.
[2]
Both directions
Allows the motor to rotate in both directions.
Parameter 4-11 Motor Speed Low Limit [RPM]
Table 263: Parameter 4-11 Motor Speed Low Limit [RPM]
4-11 Motor Speed Low Limit [RPM]
Default value: Size related
Parameter type: Range, 0 - setting in par. 4-13 RPM
Setup: All setups
Conversion index: 67
Data type: Uint16
Change during operation: True
Enter the minimum limit for motor speed. The motor speed low limit can be set to correspond to the manufacturer’s recommended
minimum motor speed. The motor speed low limit must not exceed the setting in parameter 4-13 Motor Speed High Limit [RPM].
Parameter 4-12 Motor Speed Low Limit [Hz]
Table 264: Parameter 4-12 Motor Speed Low Limit [Hz]
4-12 Motor Speed Low Limit [Hz]
Default value: Size related
Parameter type: Range, 0 - setting in par. 4-14 Hz
Setup: All setups
Conversion index: -1
Data type: Uint16
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 motor speed low limit must not exceed the setting in parameter 4-14 Motor Speed High Limit [Hz].
