Common
(Note) When no terminal is assinged, the frequency equivalent to the
current command value plus voltage command value is output.
• Reset
This digital input removes the trip condition from the drive
and cancels the fault signal.
(Note) When this function is turned on during operation, the output is cut off.

The contact condition of each multifunction input
terminal can be independently set to A -contact (NO-
normally open) or B-contact (NC-normally closed).

• Frequency match signal and frequency detect signal
These functions for the multifunction output terminals enable
output signals either when output frequency matches
command frequency or when output frequency exceeds
detect frequencies. The detect frequencies are assigned with
and separately for acceleration and
deceleration.

• Overload signal
When the output current exceeds the level set by , the
signal is output.
• PID deviation signal
A signal is output when the deviation of the target value and
feedback value exceeds the value set by during PID
control.
• Alarm signal
When a trip occurs, the multifunctional output terminal (open
collector output) outputs a fault signal.
Selection of the monitor signal
Monitor signal selection
• The output monitor from the FRQ terminal is selected.
In the case of a digital output frequency monitor, the
scale is changed by the coefficient set by . (Refer
to and .)
Multifunctional output terminal and alarm terminal contact setting
Multifunctional output terminal contact setting
Alarm terminal contact setting
• The operation specification of the multifunctional output
terminals UPF and DRV and alarm terminals AL0-AL2 can be
selected from among A-contact and B-contact.
