Terminal connection diagram (Speed control)
NOTE
For the terminal connection diagram for the position control, refer to page 90.
To prevent a malfunction caused by noise, separate the signal cables more than 10cm from the power cables. Also
separate the main circuit wire of the input side and the output side.
After wiring, wire offcuts must not be left in the drive unit.
Wire offcuts can cause an alarm, failure or malfunction. Always keep the drive unit clean. When drilling mounting
holes in an enclosure etc., take care not to allow chips and other foreign matter to enter the drive unit.

Install a thermal relay to prevent an
overheat and burnout of the brake resistor.

∗5 Terminal input specifications can be changed by analog
input specifications switchover (Pr. 267). Set the
voltage/current input switch in the "V" position to select
voltage input (0 to 5V/0 to10V) and "I" (initial value) to
select current input (4 to 20mA).
To use terminal 4 (initial setting is current input), set "4"
in any of Pr.178 to Pr.184 (input terminal function
selection) to assign the function, and turn ON AU signal.
