Great Things Come in Small Packages, including
Yaskawa Quality, Reliability and Performance
VARISPEED, the South African agent for YASKAWA AC
Variable Speed drives, the world leader in the manufacturing of AC drives,
servomotors, motion controllers and robotics, makes their presence felt once
again. This time they have done so with the introduction and release of their
new J1000 AC drive.
The drive may be the world’s smallest compact drive in size (70% less space
required), but don’t let its stature fool you as the all in one J1000 package
is still very capable of providing outstanding quality, reliability and
performance. Yaskawa has once again lived up to their reputation of providing
the automation industry with a state of the art microdrive to meet today’s
needs and demands.
The new J1000 was designed with three main principles in mind consisting of
Quality, Reduced Cost of Ownership and Maintainability. All of these allow for
the customer to get the most out of their products at a cost-effective price.
The quality of design stems partially from a reduction in the number of parts,
therefore resulting in an increased Mean Time Between Failure (MTBF) rate of an
impressive 28 years. The craftsmanship of design also increases the lifetime of
components such as fans, capacitors and thermal optimization.
The reduced cost of ownership is achieved by the compact design, side-by-side
mounting and the ability to operate a larger motor with the normal duty rating.
It also provides overexcitation braking, which in turn reduces stop times
without the need for external braking resistors. Even faster stopping can
occur, thanks to a standard internal braking transistor.
As far as maintainability is concerned, both hardware and software peripherals
such as DriveWizardTMPlus and the USB Copy Unit (Y-Stick) may be used. This
will allow for file storage that can be used to program multiple drives quickly
or for future back-up use. Maintainability is also provided by lifetime
monitors that continuously monitor the health of the key components.
The J1000 is available from 0.12 to 5.5kW. The voltage classes are 200-240V
single-phase, and 380-480V three-phase, all of which are 50/60 Hz. The J1000
shares a common programming language with its V1000 cousin as well as future released
products, ensuring quick set-up modes, easy programming, and reduced start-up
times.
Some standard features of the J1000 consist of an open loop V/f control with a
speed range of 40:1, both a normal (120% overload for 60 sec.) and heavy duty
(150% overload for 60 sec.) rating, a starting torque of 150% at 3Hz, a 5-digit
LED keypad, increased vibration resistance from 20Hz to 50Hz and a swing PWM
function to decrease audible motor noise. It also includes an output frequency
of 0-400 Hz, Modbus communication at up to 38.4 kbps, a short circuit current
rating of 30 kA rms symmetrical, an ingenious pre-maintenance function, a
preferred parameter feature and “no tools required” cooling fan replacement.
The J1000 is ideal for major applications of industries such as material
handling, food and beverage, fan and pump control, packaging, agricultural
machines and industrial washers. It includes CE, UL and cUL global
certification approval as well as keeping the environment safe by being RoHS
compliant.
