FLA,FLB,FLC These are the multifunction programmable relay contact outputs(refer
E
to page 12)The contact ratings are 250Vac-2A(COS
+
= 1 ), 30Vdc-1 A,
250Vac-1A(COS ¢ =0.4).
The standard function setting detects when the inverter protection
function have operated.
When a protection function activates, FLA-FLC will close, and FLB-FLC
will open.
P24
24Vdc power output. (Max. 1 OOmA)
F
RCH This is a multifunction programmable open-collector output(refer to
G
page 62). (Max.50mAdc)
The standard function setting activates this signal when completion of
deceleration or acceleration is detected.
LOW
This is a multifunction programmable open collector output( refer to G
page 62). (Max. 50mAdc)
The standard function setting activates this signal when a low speed is
detected.
FP This is a dedicated open-collector output. (Max.50mAdc). Pulses that H
are 48-, 96- or 360-times the output frequency are output according to
parameter settings.
The standard setting is for 48-times the output frequency.
FM This is a multifunction programmable analog output(refer to page 94. )
I
The standard setting is the pre-compensation reference frequency.
When connecting a meter, use a 1 mAdc full-scale ammeter or 7 .5Vdc-
1 mA full-scale voltmeter.
AM This is a multifunction programmable analog output(refer to page 94. ) I
The standard setting is the output current. When connecting a meter,
use a 1 mAdc full-scale ammeter or 7.5Vdc-1 mA full-scale voltmeter.
pp
This is the power supply for reference frequency setting. (1 OVdc) J
Connect a 3k
Q
potentiometer (a 1 to 1 Ok
Q
potentiometer may also be
used).
RR This is a multifunction programmable analog input. K
The standard setting is a 0 to 1 OVdc input corresponding to a O to
BOHz frequency setting.
IV
This is a multifunction programmable analog input. Change between O
L
to 1 OVdc (SW at V side) or 4 (0) to 20mAdc (SW at I side) via SW,
located under the ROM interface window. The standard setting is a O
to 1 OVdc input corresponding to a 0 to 80Hz frequency setting with the
switch at the V side.
RX This is a multifunction programmable +/- analog input. Change M
between 0 and 1 OVdc (SW at 1 OV side) or O to ±5Vdc (SW at 5V
side) via SW, located under the ROM interface window. The standard
setting is a 0 to ± 1 OVdc input corresponding to a Oto 80Hz
forward/reverse frequency setting with the switch at the 1 OV side.
cc
This is the control circuit common terminal.
