Reversible Model KBPI-240DR (120/240 VAC)
Reversing models carry out the same functions as the unidirectional models except they can
be made to index in both the forward and reverse direction. A special circuit APRM
®
provides
a lockout feature that prevents catastrophic damage to the drive if a "Reverse" command is
given during "Forward" operation (and vice versa). The reversing drives contain two additional
positions on the terminal block: "Run Rev" and "Jog Rev." The stop logic command is made
with a normally closed (NC) contact.
Note: The sense of the stop logic can be changed from normally closed (NC) to
normally open (NO) by placing jumper JS in the "NO" position.
The following wiring diagrams illustrate typical logic circuits. Many other configurations are
possible. Consult factory if help is needed.
