(2) Brushless-inverter Variable-speed Type
To change direction of belt travel, slide the reverse switch (rotation-direction selecting switch) on inverter
operating panel from CCW to CW (or from CW to CCW).
(For brushless-inverter operating panel, see p.15 or 18.)
NOTE: Before operating the reverse switch (rotation-direction selecting switch), be sure to stop the
conveyor by setting RUN/STOP switch on operating panel to “STOP” position. (For
brushless-
inverter variable-speed type, if set position of rotation-direction selecting switch is changed while
RUN/STOP switch is
in “RUN” position, belt running will be rapidly reversed and brushless
-
inverter may trip due to inertia of load. In this case alarm LED will be illuminated in red.)
2. Machine without Reverse Switch
To change direction of belt travel, remove control box cover and change electrical wiring connections as
follows:
■
Removing Control Box Cover
Loosen cover fixing bolts(*1)(one bolt on each side) and remove the cover(*2) sideways. (If difficult,
remove the entire control box from frame, and then remove fixing bolts and cover. In this case do not
loosen any of the other bolts on sides of control box.)
(1) Constant-speed Type
Connector(*3) is found in center of base plate inside box cover(*2). Press down hook(*4) on the top with
your finger and disconnect connector(*3) from base plate. Then replace it with connector(*5), which is
attached to connector(*3). (Connectors(*3, *5) can be identified by lead wire colors, red or white.)
(2) Speed-controller Variable-speed Type
On rear of speed controller, disconnect lead wire from CW terminal and connect it to CCW terminal.
