Control Circuit Terminals
Note 1. Depending on the parameter settings, various functions can be selected
for multi-function inputs and multi-function contacts outputs.
2. Functions in parentheses are default settings.
Selecting Input Method
Switches SW7 and SW8, both of which are located above the control circuit
terminals, are used for input method selection.Remove the front cover and
optional cover to use these switches.
Symbol Name Function Signal level
Input S1 Forward/Stop Forward at ON. Stops at OFF. Photocoupler
8 mA at 24 V DC
Note NPN is the default setting
for theses terminals. Wire
them by providing a com-
mon ground. No external
power supply is required. To
provide an external power
supply and wire the termi-
nals through a common
positive line, however, set
the SW7 to PNP and make
sure that the power supply
is at 24 V DC ±10%.
S2 Multi-function input 1 (S2) Set by parameter n36
(Reverse/Stop)
S3 Multi-function input 2 (S3) Set by parameter n37
(Fault reset)
S4 Multi-function input 3 (S4) Set by parameter n38
(External fault:Normally open)
S5 Multi-function input 4 (S5) Set by paramter n39
(Multi-step reference 1)
SC Sequence input common Common for S1 through S5
FS Frequency reference
power supply
DC power supply for frequency
reference use
20 mA at 12 V DC
FR Frequency reference input Input terminal for frequency
reference use
0 to 10 V DC
(input impedance: 20 kΩ)
FC Frequency reference common Common for frequency
reference use
Output MA Multi-function contact output
(Normally open)
Set by parameter n40
(during running)
Relay output
1 A max. at 30 V DC
1 A max. at 250 V AC
MB Multi-function contact output
(Normally closed)
MC Multi-function contact output
common
Common for MA and MB use
AM Analog monitor output Set by parameter n44
(Output frequency)
2 mA max. at 0 to 10 V DC
AC Analog monitor output
common
Common for AM use
