Description
When connecting the frequency setting potentiometer at an initial
status, connect it to terminal 10.
Change the input specifications of terminal 2 when connecting it
to terminal 10E. (Refer to Pr. 73 Analog input selection in
Instruction Manual (applied).)
Inputting 0 to 5VDC (or 0 to 10V, 4 to 20mA) provides the
maximum output frequency at 5V (10V, 20mA) and makes input
and output proportional. Use Pr. 73 to switch from among input 0
to 5VDC (initial setting), 0 to 10VDC, and 4 to 20mA.
Inputting 4 to 20mADC (or 0 to 5V, 0 to 10V) provides the
maximum output frequency at 20mA (5V, 10V) makes input and
output proportional. This input signal is valid only when the AU
signal is on (terminal 2 input is invalid). Use Pr. 267 to switch from
among input 4 to 20mA (initial setting), 0 to 5VDC, and 0 to
10VDC.
(Refer to Instruction Manual (applied).)
Inputting 0 to ±5 VDC or 0 to ±10VDC adds this signal to terminal
2 or 4 frequency setting signal. Use Pr.73 to switch between the
input 0 to ±5VDC and 0 to ±10VDC (initial setting).
Common terminal for frequency setting signal (terminal 2, 1 or 4)
and analog output terminal AM and CA. Do not earth.
Description
1 changeover contact output indicates that the inverter
protective function has activated and the output stopped.
Abnormal: No conduction across B-C (Across A-C Continuity),
Normal: Across B-C Continuity (No conduction across A-C)
1 changeover contact output
Switched low when the inverter output frequency is equal to or higher
than the starting frequency (initial value 0.5Hz). Switched high during
stop or DC injection brake operation.
Switched low when the output frequency
reaches within the range of ±10% (initial
value) of the set frequency. Switched high
during acceleration/deceleration and at a
stop.
*1
Switched low when stall prevention is
activated by the stall prevention
function. Switched high when stall
prevention is cancelled.
*1
Switched low when an instantaneous
power failure and under voltage
protections are activated.
*1
Switched low when the inverter output
frequency is equal to or higher than the
preset detected frequency and high
when less than the preset detected
frequency.
