Glossary
Back EMF Electromotive force (voltage) generated by a package arriving at high speed at
a powered RollerDrive under no load prior to the package’s arrival. EMF is a
counter-voltage phenomenon that is always present in a motor. Excessive back
EMF can cause a current backlash that may damage the 9006 or power
supply. Care should be taken to minimize excessive back EMF by minimizing
the speed differences between the gravity conveyor and/or different zones of
powered conveyor sections.
B sensor Downstream edge presence sensor of own zone
C sensor Downstream edge presence sensor of upstream zone
Coast mode The RollerDrive is running freely without power or braking.
DIP switch 4 Affects upstream peer-to-peer propagation of speed, jog and reverse signals
for certain scenarios.
DIP switch 5 Affects downstream peer-to-peer propagation of speed, jog and reverse signals
for certain scenarios.
Downstream Normally this is the zone to the left of another given zone. The reference is
always that packages move from upstream to downstream.
Dynamic braking For DC motors, dynamic braking is a method of stopping a motor by applying a
resistive load across the motor
winding leads after disconnection from the DC
supply. The motor operates as a generator. By its nature, dynamic braking has
no holding power by itself, i.e. the motor can still be rotated by outside forces.
Interroll has added zero motion hold to achieve this.
EC1xx Short form for Interroll 24 VDC brushless RollerDrive versions:
• EC100
• EC110
• EC120
Edge full Also referred to as "product waiting". It indicates that an upstream zone has a
product at its downstream edge sensor waiting to be moved into the next
downstream zone. Edge full is a signal transmitted across the peer-to-peer
cable used by the 9006 for zone-to-zone communication.
Enhanced Singulated release Also called wave release. A method of release which allows the upstream
release of a package as soon as the downstream package blocks the photoeye
of the downstream zone with its leading edge. This dramatically increases
throughput over singulated release but can sometimes result in lost packages.
There is also a short delay that is propagated upstream to eliminate all
packages starting at the exact same time.
Foldback current Maximum allowable current is decreased by the 9006.
