Terminal connection diagrams

A jumper is installed across terminal R1/L11 and terminal P/+, and across terminal S1/L21 and terminal N/-. When using separate power supply
for the control circuit, remove the jumpers from R1/L11 and S1/L21.

The function of these terminals can be changed with the input terminal assignment (Pr.178 to Pr.189).

Terminal JOG is also used as the pulse train input terminal. Use Pr.291 to choose JOG or pulse.

The X10 signal (NC contact input specification) is assigned to terminal MRS in the initial setting. Set Pr.599 = "0" to change the input
specification of the X10 signal to NO contact.

Terminal input specifications can be changed by analog input specification switchover (Pr.73, Pr.267). To input a voltage (0 to 5 V/0 to 10 V), set
the voltage/current input switch OFF. To input a current (4 to 20 mA), set the voltage/current input switch ON. Terminals 10 and 2 are also used
as a PTC input terminal. (Pr.561)

It is recommended to use 2 W 1 k when the frequency setting signal is changed frequently.

The function of these terminals can be changed with the output terminal assignment (Pr.195, Pr.196).

The function of these terminals can be changed with the output terminal assignment (Pr.190 to Pr.194).

No function is assigned in the initial setting. Use Pr.192 for function assignment.
 Terminal FM can be used to output pulse trains as open collector output by setting Pr.291.
 Not required when calibrating the scale with the operation panel.
NOTE
• For the system configuration examples for the parallel operation, refer to
• To prevent a malfunction due to noise, keep the signal cables 10 cm or more away from the power cables. Also, separate the
main circuit cables at the input side from the main circuit cables at the output side.
• After wiring, wire offcuts must not be left in the inverter.
Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter clean.
When drilling mounting holes in an enclosure etc., take caution not to allow chips and other foreign matter to enter the
inverter.
• Set the voltage/current input switch correctly. Incorrect setting may cause a fault, failure or malfunction.
