* The given setting range is valid if Heavy Duty is selected (C6-01=0, default setting). If Normal Duty 1 or 2 is selected (C6-01=1 or 2) the setting range will
be 0.0 to 400.0 Hz.

Description
Range
Sets the detection level for the
output frequency detection
function. Effective when a
0.0 to
multi-function digital output is
150.0
set to:
• 3 (f / f agree 1)
out set
• 4 (Frequency detection 1)
• 5 (Frequency detection 2)
Sets the hysteresis for the out-
put frequency detection func-
tion. Effective when a multi-
function digital input is set to:
0.0 to
• 2 (f / f agree 1)
20.0
ref out
• 3 (f / f agree 1)
out set
• 4 (Frequency detection 1)
• 5 (Frequency detection 2)
Sets the detection level for the
output frequency detection
function. Effective when a
-150.0
multi-function digital output is
set to:
+150.0
• 14 (f / f agree 2)
out set
• 15 (Frequency detetcion 3)
• 16 (Frequency detection 4)
Sets the hysteresis for the out-
put frequency detection func-
tion. Effective when a multi-
function digital input is set to:
0.0 to
• 13 (f / f agree 2)
20.0
ref out

0: Stop (Operation follows
the frequency reference.)
1: Operation continues at the
frequency, set in parameter
L4-06. 0 or 1
Frequency reference loss
means that the frequency
reference value drops over
90% in 400 ms.
Sets the frequency reference
0.0 to
value when the frequency ref-
100.0%
erence is missing
When the frequency reference
drops by this value within
10 to 80
400ms frequency reference
loss is detected.
