4-10 Motor Speed Direction

Selects the motor speed direction required.
Use this parameter to prevent unwanted reversing. When
4-10 is internally set to Clockwise [0] only.
[0] Clockwise
* Both directions

NB!
The setting in par.4-10 has impact on the Flying Start in par.1-73.

4-53 Warning Speed High

Range:
*
par. 4-13 RPM [Par. 4-52 - par.
4-13 RPM]
NB!
Any changes in par. 4-13, Motor Speed High Limit [RPM] will reset the value in par. 4-53 to the same value as set in par. 4-13.
If a different value is needed in par. 4-53, it must be set after programming of par. 4-13!

Only operation in clockwise direction will be allowed.
Operation in both clockwise and anti-clockwise direction will be allowed.
Function:
Enter the n value. When the motor speed exceeds this limit (n
HIGH
outputs can be programmed to produce a status signal on terminal 27 or 29 and on relay output 01 or 02.
Programme the upper signal limit of the motor speed, n
converter. Refer to the drawing in this section.
Function:
- Enter the lower feedback limit. When the feedback falls below this limit, the display reads Feedb Low. The signal
outputs can be programmed to produce a status signal on terminal 27 or 29 and on relay output 01 or 02.
Function:
Enter the upper feedback limit. When the feedback exceeds this limit, the display reads Feedb High. The signal
outputs can be programmed to produce a status signal on terminal 27 or 29 (FC 302 only) and on relay output
01 or 02 (FC 302 only).
Function:
