Yaskawa J7 Drive - Manual (Page 6)

5. Digital Operator
The DSPL button cycles through all of the quick start LEDs.
To access a parameter, press the DSPL button until the PRGM LED is on. Use the UP
and DOWN keys until the desired parameter number is displayed, then press ENTER.
Use the UP and DOWN keys to adjust the value then press ENTER then DSPL.
Before the drive will accept a RUN command, one of the following LEDs must be on:
FREF, FOUT, IOUT, MNTR, or F/R. For more specific information on the digital
operator, see the Tech. Manual, Section 4.
6. Choose a configuration from Table 1 below. Each example listed below contains a
control wiring diagram, operation explanation, and all necessary programming. The
drive can be controlled in many more ways than is described in these examples.

Description
Digital Operator Digital Operator This method requires no control wiring connections to the drive. It is
most often used during startup of the drive.
2-wire 4-20 mA
With this method the drive can be started and stopped from a remote
source, and the reference comes from a remote 4 – 20 mA source
such as a PLC.
3-wire
Speed
Potentiometer
With this method, remote pushbuttons start and stop the drive and the
reference comes from a speed control (potentiometer).
7. Control Terminal Wiring – Remove power and wait for all LEDs to go out before
making control terminal connections.
Control wiring should be sized 16 to 20
AWG. Control wiring should be shielded,
with the shield wire connected to the ground
terminal , which is located towards the left
side of the aluminum heat sink.
