2.3 Wiring
(1) Untwist the twisted pair shielded cables after stripping its sheath.
Also, perform protective treatment of the shield to ensure that it will not
make contact with the conductive area.
Strip off the sheath about the size as in the below figure. If the length of
the sheath pealed is too long, a short circuit may occur among
neighboring wires. If the length is too short, wires might come off.
Wire the stripped cable after twisting it to prevent it from becoming loose.
(Do not solder it.)
Use a bar type terminal as required.

INSTALLATION AND WIRING
(3) For wiring of the inverter which has one front cover, route wires between the control circuit terminal block
and front cover. If cables can not be routed between the control circuit terminal block and front cover
due to the increased number of cables, remove a hook of the front cover and use a space become
available.
For wiring of the inverter which has front cover 1 and 2, use the space on the left side of the control
circuit terminal block.
REMARKS
• When the hook of the inverter front cover is cut off for wiring, the protective structure (JEM1030) changes to open
type (IP00).
When performing wiring using the space between the inverter front cover and control circuit
terminal block, take care not to subject the cable to stress.
After wiring, wire offcuts must not be left in the inverter. They may cause a fault, failure or
malfunction.
Cut off a hook on the inverter
front cover side surface.
(Cut off so that no portion is left.)

4.1 Wiring Example
Use Pr. 525 to Pr. 532 and Pr. 537 to output analog signals, such as output frequency and output current,
from the voltage output terminals (DA2 to DA5).
The voltage output terminals are updated more frequently than the terminals FM/AM/CA* of the inverter.
Thus, high-speed monitoring is available with these terminals. (Refer to page 19 for high-speed monitoring.)
* Terminals provided differ according to the inverter.
Connect the voltmeter as shown below:

4.3 Calibration procedure
4.3.1 Calibration of voltmeter
If a voltmeter is deviated, it can be calibrated at 0V or full-scale voltage (10V) output of the terminals DA2
to DA5.
(1) Calibration at 0V output
In the initial status, 0V calibration is performed
at power OFF →ON and at inverter reset.
To perform 0V calibration after the power has
been turned ON, turn ON the X83 signal. To
use the X83 signal, assign the 0V calibration
request signal (X83) to an input terminal
beforehand. While the 0V calibration is
performed, the during 0V calibration signal
(Y83) is ON.
* To input the X83 signal, set "83" in one of Pr.178 to Pr.189 (input terminal function selection) to assign the function to a
terminal.
To output the Y83 signal, set "83 (positive logic)" or "183 (negative logic)" in one of Pr.190 to Pr.196 or Pr.533 to Pr.536
(output terminal function selection) to assign the function to a terminal. To output the LF signal, set "98 (positive logic) or
198 (negative logic)" to assign the function.
REMARKS
• The alarm signal (LF) turns ON if 0V calibration fails.
• Output signals are undetermined while the Y83 signal is ON. The Y83 signal does not turn ON while the power is
ON or during inverter reset.

During calibration,
the high-speed analog output is 0.

CAUTION
• Keep the X83 signal ON for 20ms or longer. Otherwise, calibration may not be performed.
• When the X83 signal is assigned, 0V calibration is not performed at power ON and at inverter reset. If power
is turned OFF while the X83 is assigned, a 0V-calibrated value returns back to the logical value because the
inverter does not save such calibrated values.
• Changing a terminal assignment using Pr.178 to Pr.189 (input terminal function selection) and Pr.190 to Pr.196 or
Pr.533 to Pr.536 (output terminal function selection) may affect other functions. Set parameters after confirming the
function of each terminal.
