Warning Speed High
Function:
Enter the lower reference limit. When the actual reference falls below this limit, the display indicates
Ref 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 reference limit. When the actual reference exceeds this limit, the display reads Ref
High. 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 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 and on relay
output 01 or 02.
Function:
Displays an alarm in the event of a missing motor phase.
Select 100 ms to have a short detection time and alarm in the event of a missing motor phase. 100
ms is recommended for hoisting applications.
No alarm is displayed if a missing motor phase occurs.
An alarm is displayed if a missing motor phase occurs.
