Danfoss VLT HVAC Series User Manual

3.6.3 4-5* Adj. Warnings
Define adjustable warning limits for current, speed, reference and feedback.
NOTE!
Not visible in display, only in VLT Motion Control Tool, MCT 10.
Warnings are shown on display, programmed output or serial bus.
4-50 Warning Current Low
Range: Function:
0.00 A* [0.00 - par. 4-51 A] Enter the I
LOW
value. When the motor current falls below this limit (I
LOW
), the display reads CURRENT
LOW. The signal outputs can be programmed to produce a status signal on terminal 27 or 29, and
on relay output 01 or 02. Refer to the drawing in this section.
4-51 Warning Current High
Range: Function:
par. 16-37
A*
[par. 4-50 - par. 16-37 A] Enter the I
HIGH
value. When the motor current exceeds this limit (I
HIGH
), the display reads CURRENT
HIGH. The signal outputs can be programmed to produce a status signal on terminal 27 or 29, and
on relay output 01 or 02. Refer to the drawing in this section.
4-52 Warning Speed Low
Range: Function:
0 RPM* [0 - par. 4-53 RPM] Enter the n
LOW
value. When the motor speed falls below this limit (n
LOW
), the display reads SPEED
LOW. The signal outputs can be programmed to produce a status signal on terminal 27 or 29, and
on relay output 01 or 02. Program the lower signal limit of the motor speed, n
LOW
, within the normal
working range of the adjustable frequency drive. Refer to the drawing in this section.
