Any changes in 4-13 Motor Speed High Limit [RPM] will reset
the value in 4-53 Warning Speed High to the same value as set
in 4-13 Motor Speed High Limit [RPM].
If a different value is needed in 4-53 Warning Speed High, it
must be set after programming of 4-13 Motor 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.
