Description
Used to set the input characteristics of
analog frequency references.
Gain: The frequency of maximum analog
input (10 V or 20 mA) in percentage based
on the maximum frequency as 100%. on the maximum frequency as 100%
Bias: The frequency of minimum analog
input (0 V or 0 or 4 mA) in percentage
based on the maximum frequency as
100%.
Used to set the digital filter with a first-or-
der lag for analog frequency references to
be input.
---
Selects the frequency loss detection func-
tion for when the frequency reference from
the control circuit terminal suddenly drops.
0: Disable (Operate according to frequency
reference.)
1: Enable (Continue operation at 80% of
frequency reference prior to loss.)
Note: Frequency reference loss: Frequen-
cy reference voltage drop of 90% within
400 ms.
Selects the multi-function analog output
type.
0: Analog voltage output (functions set in
n066)
1: Pulse train output (functions set in n150)
