6.4 Reverse Functions
The AFC1500 stand alone System is capable of reverse operations using the manual reverse input
on the SAN unit front panel or via the PLC input. The PLC input can be used for automated reverse
operations. The motor will reverse as long as the reverse signal or manual button is enabled.
As a stand alone SAN Unit, only one reverse speed is available. If the spindle is controlled by a
MULTI Unit, 3 reverse speeds are available.
FIG. 6-4 SAN Unit Reverse (Without MULTI Unit)
The reverse function on a stand alone SAN Unit is set with one speed setting (Reverse 1,2 Speed).
The duration of the reverse would be controlled from an external source (PLC) using the “Reverse”
input or manual reverse pushbutton.
FIG. 6-4b SAN Unit Reverse (With MULTI Unit)
The reverse function controlled by the MULTI Unit has added function. Three separate reverse
speeds can be set-up. REVERSE 1 can only be set-up using a time limit from the MULTI sequence.
REVERSE 2 and REVERSE 3 are set-up using the number of desired revolutions (Revs.).
A Breakaway torque limit can also be set for REVERSE 2 and 3 to check breakaway torque on re-
versing applications. An Abnormal will be generated if the breakaway torque is over the preset limit.
