Either control circuit terminal 13 or 14 can be used. (For simultaneous inputs, the two
2.
signals are added internally.)
Control circuit terminal 15/33 of +15 V/−15 V has a maximum output current capacity
3.
of 20 mA.
Multi−function analog output should be used for monitoring meters (e.g. output
4.
frequency meter) and should not be used for feedback control system. Use analog monitor
cards (Model AO−08 or AO−12) for the control system, for a more accurate signal.
When using a braling resistor unit, set the constant L3−04 to "0" (stall prevention level
5.
during decel is "disabled"). If it is not changed, the motor may not stop within the set decel
time.
When using model ERF braking resistor (inverter−mounted type), set the braking resistor
6.
protection selection to "enabled". If it is not changed, the braking resistor cannot be pro-
tected.
When installing a DC reactor (optional for models of 15 kW or below), remove the short−
7.
circuit bar between ¨1 and ¨2 terminals and connect a DC reactor with the terminals.
Select RS−422 or RS−485 of serial communication (terminals 40 to 43) by using the dip
8.
switch on the control PC board. The terminal functions differ between RS−422 and
RS−485.
