indicates shielded wires and
indicates twisted-pair shielded wires.
2.
Either control circuit terminal 13 or 14 can be used. (For simultaneous inputs, the two
signals are added internally.)
3.
Control circuit terminal 15/33 of +15 V/-15 V has a maximum output current capacity of
20 mA.
4.
Multi-function analog output should be used for monitoring meters (e.g. output frequency
meter) and should not be used for feedback control system. Use analog monitor cards
(Model AO-12) for the control system, for a more accurate signal.
5.
When using a braking resistor unit, set the constant L3-01 to “0” (overvoltage prevention
level is “disabled”). If it is not changed, the motor may not stop within the set decel time.
6.
When using model ERF braking resistor (inverter-mounted type), set the constant L8-01
to “01” (braking resistor protection selection to “enabled”). If it is not changed, the brak-
ing resistor cannot be protected.
7.
When installing a DC reactor (optional for models of 15kW or below), remove the short-
circuit bar between ¨1 and ¨2 terminals and connect a DC reactor with the terminals.
8.
The models of 200V 30 to 75kW or 400V 55 to 160kW cannot be connected with DC pow-
er supply.
9.
Once external baseblock signal is turned ON, do not release until a motor stops.
