Varispeed -505WII
INDUSTRIAL USE THYRISTOR CONVERTER UNITS
Before initial operation, read these instructions thoroughly, and retain for future reference.
YASKAWA
When properly installed, operated and maintained, this
unit will provide a lifetime of optimum operation. It is
mandatory that the person who operates, inspects, and
maintains this equipment thoroughly reads and understands
this manual and has In his possession at all time.
IMPORTANT
• Make no withstand voltage test on the VS-505WII because
it Incorporates semi-conductor electronic circuits.
• If insulation resistance tests are neccessary, make them
only In accordance with the Instructions given in this
manual.
• Do not tamper with potentiometers of the power units
since they were preset at the factory before shipment.
Varispeed-505WII (VS-505WII) is a thyristor converter unit
for varispeed reversible operation of industrial DC
motors.
For correct operation of VS-505WII, users must
thoroughly read these instructions. This manual is also
necessary for maintenance and troubleshooting, and
threfore should be kept filed for ready reference.
For details on DC motors, refer to "Instructions for
Industrial DC Motors" CTOE-C435-3B).

Notes :
■ Terminal size other than listed above is M4 and current
capacity is 2 A or below.
• Rule of thumb of AC main circuit power capacity 1.2 x/3
x e X I (VA)
E : Supply voltage I : AC main
circuit current
Make connections of VS-505WI with associate units
according to the interconnection diagram separately
furnished.
CAUTIONS WHEN WIRING
Main Circuits
Use 600 V PVC insulated wires or cabtyre cables with the
current carrying capacities of the combined DC motor for AC
main circuit terminals (U, V
,
W) and DC main circuit
terminals (P, N).
Field Circuits
Use 600 V PVC insulated wires or cabtyre cables with the
current carrying capacities of the combined DC motor for
field power circuit terminals (Uo, Wo» Ui, Wi) and field
circuit terminals (J, K). Use stranded wires of cross-
section 5.5 mm
2
or larger for field circuit terminals (J,
K).
Signal Circuits
Use shielded wires or twisted wires of twisting pitches 20
mm or smaller for the speed setting circuit terminals (6 to
10
),
speed feedback terminals (2, 3), tachometer circuit
terminals (50 to 52).
