Selection Procedures
Select the Proper Clutch/Brake
Determine torque and inertia requirements.
Calculate heat dissipation for required cycle rate.
For best accuracy, mount clutch/brake directly on
nip or drive shaft. Avoid backlash.
Select Encoder (Quadrature)
Select encoder PPR for desired system resolution
(i.e., inches/pulse, degrees/pulse. Determine input
frequency; do not exceed 20 KHz (20,000 pulses/
sec). Mount encoder directly to nip or drive shaft for
best accuracy. Refer to Encoder Selection, page 7.
Select Clutch/Brake Power Supply
Use CBC-700 overexcitation control for best accu-
racy. Use CBC-500/550 for soft starting and/or
stopping. Note: Brake autogap may have to be
removed for best accuracy. Refer to clutch/brake
control, page 7.
Plan System Logic (Switching Requirements)
Use absolute mode for indexing applications such
as conveyors and turntables or cutoff applications
where close registration is required. Use
incremental mode for cutoff applications where
close registration is required. Use incremental mode
for cutoff applications. Refer to mode of operation,
page 8. Determine switching and relays required for
machine operation. Refer to pages 14-19 for
specific wiring options. Examples of incremental and
absolute wiring schematics are shown on pages 18
and 19.
Calculate Scaling Factor
Reference display scaling, page 8, to scale the
display to read inches, meters, degrees, rotations,
etc.
Determine Program Steps
Select absolute or incremental mode, output delays
and other options. Refer to Programming Section,
page 12.
Serial Communications
For data collection or remote operation, refer to
Serial Interface on pages 20-23.
