> The German hundred standards pull three-phase
mixed style step of 进电 machine VRDM3913 and its necessary driver
WD3-007 besides have the common step of 进电 machine characteristic,
its originality is: This three-phase mixed style step 进电
machine uses the exchange servo principle work, the rotor and the
stator diameter compared to reaches as high as 50%, high speed when
works the torque to be big, when low speed moves extremely steadily,
nearly does not have 共振? Its necessary driver has the
single-phase 220V/50Hz input, the three-phase sine output, the output
current may establish, has ten subdivides with partly flows the rated
value 60% function; The control mode is flexible, has "the pulse
+ directional control", also has "the clockwise pulse + reverse pulse"
the control mode; Has had the hot protection function, therefore
uses extremely convenient. As a result of driver output current 3A, voltage 325V, in
addition its outer covering has not used the aluminum, the titanium,
the magnesium alloy outer covering carries on the magnetic shield,
therefore creates the disturbance to the high keen receiver system,
causes it to be unable to work, and pollutes the power source, creates
the control system the monolithic integrated circuit and on the
position machine is unable to carry on the communication, serious
creates monolithic integrated circuit dying machine, has caused the
difficulty for the normal use, therefore the disturbance question must
perform to solve. The author in made in the system to take the following
measure: A. installs the power source filter, reduces to the
alternating current supply pollution. B."as soon as accepts after checking" the principle.
The power source filter place, driver PE () (driver and engine
case ledger wall insulation), control pulse PULSE- and the direction
pulse DIR- 短接 after lead-out wire, the electrical machinery meet
between the grounding, the driver and the electrical machinery the
electric cable protecting jacket, the driver shielded wire receives on
the engine case wall to meet on the plume, and the request contact is
good. C. enlarges the pilot wire and the power line as far as
possible (L, N), the electrical machinery drive line (U, V, W) the
between distance, avoids overlapping For instance we when the
processing tandem-drive system two occupy the identical engine case
driver to install the position, a driver data plate faces forward,
after another faces, and causes these lead wires in the structural
arrangement to be as far as possible short. D. uses the shielded wire to reduce the outside for own
disturbance, or own (power line) foreign disturbance. Processes after below, the WD3-007/VRDM3913 step of 进电
machine actuation system passed through more than two years of actual
movements tests to prove above processing method appropriate, the
system work was reliable. |
