Introduction
The CBPC-3590 Clutch Brake Positioning Control
is a dedicated control incorporating a counter
system, control logic, and clutch brake power
supply for closed loop control operation . The
controller uses an incremental encoder input with
marker pulse to register position for single
revolution operation .
The one board design eliminates interconnec-
tion between numerous boards and controls and
improves reliability by removing unnecessary
interconnecting cables . With everything located
on one board, replacement of the control board is
simplified .
An external start input signal is used to provide
the start input to the controller which applies
power to the clutch. The encoder registers the
position to the controller and when the preset
count is reached turns power on to the brake. An
internal averaging circuit takes the actual stop
position from the required stop position and
compensates so the controller provides the stop
at the precise position . In this method,
compensation is maintained in the stop position
from cycle to cycle .
The control has front panel indicators to tell when
the clutch is on, brake is on, a fault has occurred
and a home pulse indicator . In addition, a front
panel run-jog switch allows the user to oper-
ate the control in normal running mode or in jog
mode for set up and troubleshooting purposes .
When in the jog mode, the jog push-button allows
the clutch to be activated at a preset level below
the maximum set output level. The clutch will be
engaged as long as the push-button is held in and
brake is actuated as soon as it is released.
This control will directly replace the older style
CBC1500-AHFC controller. Connectors are
provided on the housing of the control for
hook-up to existing cables where the
CBC1500-AHFC is used. If existing cables are
non-existent, optional cable accessories are
available .
Set up has been simplified to minimize the
number of steps necessary to commission the
unit . All functions are accessed internally in the
controller via the keypad and display. Once the
unit is set up and closed, the operator does not
have access to any of the functions without going
into the controller . Remote indicators on the
faceplate show the status of the controller.
Theory of Operation
The CBPC-3590 operation is simple and straight
forward. The unit is typically setting with the brake
output engaged . A “start input” signal is received
by the control from the external signal source . The
controller disengages the brake and applies
power to the clutch. The output level to the clutch
is adjustable via the programming mode to obtain
the proper engagement of the clutch . With the
clutch engaged, the drive mechanism starts to
rotate generating a signal to the controller from
the encoder . The controller counts the encoder
pulses and the display (internal) counts in an up
direction . If the count is in the reverse direction,
then the encoder signals “A” and “B” are
improperly connected and need to be reversed for
