Glossary
~STOP
The logical inverse of STOP. This circuit must be closed for the ZENER 8000-V to
run.
2-wire control
Control of the stop / start function by a simple contact closure (eg a start / run
switch contact).
3-wire control
Control of the stop / start function by momentary contacts, typically separate
start and stop pushbuttons. This arrangement has the advantage of preventing
an inadvertent re-start following a power outage.
COM
The common terminal to which all inputs on the ZENER 8000-V are referenced.
AWG
American Wire Gauge
Console
The pushbuttons and LCD display on the front of the ZENER 8000-V
Constant Torque
A load characteristic in which the driving torque requirement is largely
independent of speed. e.g. a horizontal conveyor
DC Bus Choke
An inductor connected in series with the DC bus inside the ZENER 8000-V. This
provides several benefits including reducing the harmonic content of the AC line
current.
EMC
Electromagnetic Compatibility. The arrangement of emission and immunity
levels to achieve functional coexistence between various items of equipment in a
given environment.
EN
The enable input on the ZENER 8000-V.
ESO
Essential Services Override. A mode of operation that disables certain protection
features in order to allow the ZENER 8000-V and/or the motor to run to
destruction in certain circumstances, for example clearing smoke from a
building.
HVAC
Heating, Ventilation and Air Conditioning [industry]
IEC
International Electrotechnical Commission, publisher of many standards related
to electrical / electronics technology.
IN+, IN-
These are the designations of differential analogue inputs on the ZENER 8000-V.
The
ZENER 8000-V will respond to the difference between the two inputs, rather
than the
voltage between either input and AN COM.
JOG
A control input that causes motion only while it is active (ie non-latched) that is
usually used to manually operate equipment for the purposes of setting up or
alignment prior to continuous operation.
LATCH
A feature of a control input that requires only a momentary signal (e.g. contact
closure) to provide sustained (latched) operation.
Local
Operation of the ZENER 8000-V from the console pushbuttons on the enclosure.
