tion
Perform the above setting according to the source of the frequency reference in the application.
When frequency references from the DeviceNet communications are to be always used, set to "9." If
this setting is performed, frequency reference 1 can only be set through DeviceNet communications.
However, frequency references 2 to 16 and the inching frequency can be set from DeviceNet com-
munications or the Digital Operator regardless of the setting of n004.
Name Content
Selects the frequency refer-
ence input method for the
Inverter. (Becomes valid when
the Remote mode is selected
from Local/Remote.)
0: Digital Operator frequency
settings are valid.
1: Frequency reference 1
(n024) is valid.
2: Frequency reference control
terminal (0 to 10-V voltage
input) is valid.
3: Frequency reference control
terminal (4 to 20-mA current
input) is valid.
4: Frequency reference control
terminal (0 to 20-mA current
input) is valid.
5: Pulse train reference control
terminal is valid.
6: Frequency reference from
RS-422/485 communications is
valid.
7: Multi-function analog voltage
input (0 to 10 V) is valid. (Used
when two analog inputs are
required for PID control. Nor-
mally not used.)
8: Multi-function analog current
input (4 to 20 mA) is valid.
(Used when two analog inputs
are required for PID control.
Normally not used.)
9: Frequency reference from
the Optional Unit (DeviceNet
Communications Unit) is valid.
