*1:
Terminals PR and PX are provided for the FR-A520-0.4K to 7.5K, FR-A540-0.4K to 7.5K.
*2:
Low indicates that the open collector outputting transistor is on (conducts).
High indicates that the transistor is off (does not conduct).
*3:
Not output while the inverter is reset.
Terminal Name
10VDC, permissible load
current 10mA
5VDC, permissible load current
10mA
By entering 0 to 5VDC (0 to 10VDC), the maximum output frequency is reached at
5V (or 10V) and I/O are proportional. Switch between input 0 to 5VDC (factory
setting) and 0 to 10VDC from the operation panel. Input resistance 10k . Maximum
permissible voltage 20V.
By entering 4 to 20mADC, the maximum output frequency is reached at 20mA and I/
O are proportional. This input signal is valid only when the AU signal is on. (Voltage
input is made invalid) Input resistance approximately 250 . Maximum permissible
current 30mA.
By entering 0 to ±5VDC or 0 to ±10VDC, this signal is added to the frequency setting
signal of terminal 2 or 4. Switch between input 0 to ±5VDC and 0 to ±10VDC (factory
setting) from the operation panel. Input resistance 10k . Maximum permissible
voltage ±20V.
Common to the frequency setting signal (terminal 2, 1 or 4) and analog output
terminal AM. Do not earth (ground).
1 contact output indicating that the output has been stopped by
the inverter protective function activated.
230VAC 0.3A, 30VDC 0.3A. Alarm: discontinuity across B-C
(continuity across A-C), normal: continuity across B-C
(discontinuity across A-C).
Switched low when the inverter output frequency is equal to or
higher than the starting frequency (factory set to 0.5Hz, variable).
Switched high during stop or DC injection brake operation (*2).
Permissible load 24VDC 0.1A. (A voltage drop is 3.4V maximum
when the signal is on.)
Switched low when the output frequency has reached within
±10% of the set frequency (factory setting, variable). Switched
high during acceleration, deceleration or stop (*2). Permissible
load 24VDC 0.1A.
Switched low when the stall prevention function has caused stall
prevention to be activated. Switched high when stall prevention is
reset (*2). Permissible load 24VDC 0.1A.
Switched low when instantaneous power failure or undervoltage
protection is activated (*2). Permissible load 24VDC 0.1A.
Switched low when the output frequency has reached or
exceeded the detection frequency set as appropriate. Switched
high when the output frequency is below the detection frequency
(*2). Permissible load 24VDC 0.1A
Common to the RUN, SU, OL, IPF and FU terminals.
One selected from 16
monitoring items, such as
output frequency, is output. (*3)
The output signal is
proportional to the magnitude
of each monitoring item.
With the operation panel connector, communication can be made through RS-485.
