Data selected between the following
items is output with DC voltage:
z
Output frequency
z
PID feedback value
z
Output current
z
DC link circuit voltage
* Up to two analog voltmeters (input
impedance : 10 k
Ω)
can be connected.
Note:
Output waveform: An AC pulse
is output with consistent frequen-
cy and variable duty.
The average DC voltage is pro-
portional to output frequency and
output current
(frequency : 121.6 Hz).

Alarm output for
any fault
If the inverter is stopped with an alarm,
the non-voltage contact signal (1SPDT)
is output
(Contact rating: 250V AC, 0.3 A, Power
factor = 0.3)
(48V DC, 0.5A for Low-voltage Directive
or 42V DC, 0.5A for UL/cUL)
* Whether an alarm is generated with an
exciting operation or non-exciting opera-
tion can be switched.
