■ Basic Wiring Diagram
(Operation by External Signal)
● This is the basic inverter wiring diagram when operating by using
forward and reverse switches, an external potentiometer etc.
● For safety, install a magnetic contactor on the input side.
Notes: 1. To install the model MRS optional external brake resistor to increase
braking power, connect it between terminals PR and P (+).
2. Set Pr. 54 to be able to select an output current display rather than
frequency.
3. Since Pr. 900 can be used to calibrate the scale of the display meter,
there is no need for a scale calibration resistor except when remote
calibration is required.
■ Basic Wiring Diagram
(Main Circuit Input Cut-Off by Alarm)
● This is the circuit when cutting off the main inverter circuit input
with a magnetic contactor when an inverter alarm stop occurs.
● The terminal FM-SD output can be either a frequency or a motor
current signal. (See the description of Pr. 54 on page 21 for
details.)
● For reset input, you can also select a function (error reset) that
accepts signals only when the inverter alarm stops. (See the
description of Pr. 75 on page 23 for details.)
