Page 8: Instruction Of Power Supply
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. - Page 9 SELECTION AND MATCH OF SPEED FEEDBACK VOLTAGE (While it is ready to leave the factory, otherwise, T/G gradient will be set at 7V/1000rpm) TACHOGENERATOR (T.G.) can be adopted for the speed feedback of CDS-E Series. Analog voltage input (F/V) converted from Frequency can also be used.

- Page 20 (5) T.F Abnormal Speed feedback Display (LED ON)： Trip-off protections of abnormal speed feedback can be classiffollied into the following two categories. (The trip-off protection at uncontrolled speed is OPTIONAL, the corresponding model code is F .) 1. First category：when the power supply voltages of main power U1,V1 reach lower limits, the trip-off protections will be activated (T.F LED on).

Page 21: Adjustment
Adjustment Instructions (setting knobs on panel board) (please refer to adjustment instructions appendix) 1.ZERO Voltage Adjustment (also called Balance Adjustment and OFFSET Adjustment) (18- ： rotation type of long micro-variable resistor) When V command is setup to 0, the motor shall be in HOLIDING status. If rotation still occurs, the setting knob shall be adjusted either in clockwise or counterclockwise direction to set motor's speed to be zero.(If OFFSET floats abnormally, the voltage command and the isolation effect of speed feedback signal shall be inspected or improved.) - Page 22 Appendix of Adjustments Instructions AC.G Dynamic Response Adjustment If the motor is purchased from our company, it shall be set in optimal condition when delivered from factory. However, if the motor is purchased through other sources, it will be set in 50% position. Note：Each model's loading conditions are different, for better soothing motion and higher dynamic following precision, it shall be referred to the previous page of "...
