R/W Description
R/W Sets the allowable PID loop error
magnitude (absolute value), SP-PV,
range is 0.0 to 100%, resolution is
0.1%
R/W When the PV exceeds this value,
the PID loop turns OFF the PID
second stage output, range is 0.0 to
100%
R/W When the PV goes below this value,
the PID loop turns ON the PID
second stage output, range is 0.0 to
100%
R/W Two option codes:
02 OPE or option
03 ModBus (485)
NOTE: These network settings are
not accessible to ModBus. Use the
inverter keypad or digital operator
to edit. Refer to "Network
Communication Settings" on page
3–60.
R/W Scale factor between the external
frequency command on terminals
L–O (voltage input) and the
frequency output,
range is 0.0 to 200%
frequency command on terminals
L–OI (voltage input) and the
frequency output,
range is 0.0 to 200%
R/W Offset adjustment of AM output.
Range is 0.0 to 10.0
Adjust together with B080 (AM
gain adjustment)
Displays debug parameters.
Two option codes:
00 Disable
01 Enable
Controls speed setpoint for the
inverter after power sycle.
Two option codes:
00 Clear last frequency (return to
default frequency F001)
01 Keep last frequency adjusted
