*2 Remove the short-circuit bar (normally connected) from between terminals
¨1 and ¨2 when connecting a DC Reactor (Optional).
*3 Disable stall prevention during deceleration by setting L3-04 to “0” when us-
ing a Braking Resistor Unit. The motor may not stop within the deceleration
time if this setting is not changed.
