INSTRUCTION OF POWER SUPPLY
Supplying AC power to CDS-E Series shall be fine since the Series is equipped
with built-in rectifying system. On the panel board of driver : U1V1 is the main
power, U2V2 is power supply terminal of control system.
Specifications of Supply Voltage
AC110V , 50/60HZ
Max. allowable change: AC90V~128V
Input current 0.7A (min)
or higher
V1
V2
U2
U1
EXAMPLE:CDS - □□10 FECW
Input voltagr 30~70VAC (max.tolerance 15% or below)
EXAMPLE:CDS-□□15 FECW
Input voltagr 30~7110VAC (max.tolerance 15% or below)
(1) Voltage stabilizer should be installed in environment with great current and voltage variance.
(2) The driver will trip-off if breaking occure on the main input current and voltage of U1V1 alone (the
T.F. LED on the panel board lights up). After the problem is corrected,the power will be supplied
through automatic reset. If the power supply is over AC80V,the rectifying system or power unit
may be damaged. In case that the power supply is below or upon critical AC25V, voltage decrease
may occur during heavy load. So the driver may not be able to run smoothly owing to the abnormal
feedback. (The motor will vibrate with low frequency, make noises, or stop intermittently.) In
more serious cases, the situations shall be deem as breaking on U1.V1, leading to the tripping-off
of T,F with lit LED. After the problem is corrected, the power will be supplied through automatic
reset.
(3) If the power supply for the control system, U2,V2, is over AC128V, it may cause damages to
internal elements. If the power is below AC90V, the driver can not operate. (If the power supply is
about the lower critical limit, unstable enable may occur intermittently).
(4) Generally speaking, power improvement device (e.g.:isolated transformer) should be installed at
the front end of main power supply in order to improve the quality of supplied power.
(5) Proper treatments should also be performed in environment with worse quality of power supply
for better performance. For example, the power input terminal should not be for use with other
equipment; cables with strong signal interference should avoid from put in same wireduct and
should be grounded accurately; or filter and surge absorber should be installed otherwise.
