！
Caution: • Be sure to install a serge killer circuit when inductive switches, such as
relays, are used.
！
Caution: • When you install sensors such as “Home position limit switch,”
“+ direction sensor of over travel limit switch” and “- direction of over
travel limit switch,” connect output of those sensors directly, not via the
controller. (Those outputs are shown as
in Figure 3-6 below.)

l Home Return
à For an example, write HS command to channel CH0 and then;
à Select the CH0 to start the Home Return (RUN input ON) after turning on the power
and complete the Home Return.
l Pulse train command operation
à When control the System by the pulse train input command, add connections to CWP ±
and CCWP ± signals.
*1: The parameter OM selects one of outputs from among BRK (Brake), SPD (Velocity
threshold), NEARA (Near proximity/In target), and OVER (Warning) for OUT1. The
shipping set is BRK.
