Set n137 to the feedback level in percentage based on the feedback level at maximum
frequency as 100%.
·
Set n138 in 0.1-s increments for the permissible continuous period of
t
he feedback sig-
nal level that is the same as or less than the feedback level set in n137.

·
Set this parameter to a rate by which PID control value is multiplied for PID control.
·
Normally, the default setting does not need to be changed.
·
This parameter is used for the adjustment of the PID control value to be added with the
frequency reference.

Value Description
0 Frequency reference control terminal for 0- to 10-V voltage input is enabled.
(see note 1)
1 Frequency reference control terminal for 4- to 20-mA current input is enabled.
(see note 2)
2 Frequency reference control terminal for 0- to 20-mA current input is enabled.
(see note 2)
3 Multi-function analog voltage (0- to 10-V) input is enabled.
Used only if two analog inputs are required in PID control.
4 Multi-function analog current (4- to 20-mA) input is enabled.
Used only if two analog inputs are required in PID control.
5 Pulse train reference control terminal is enabled. (see note 3)
Note 1. The maximum frequency (FMAX) is reached with 10-V input.
Note 2. The maximum frequency (FMAX) is reached with 20-mA input, if the SW2 on
the control PCB was changed from V (voltage) to I (current).
Note 3. Set n149 for the pulse train input scale to the pulse train frequency that is equiv-
alent to the maximum frequency (FMAX).
Note 4. Make sure that the target value input and feedback value input do not overlap
with each other.
