4.5.2 Adjusting Encoder Voltage
You may adjust the Encoder Power Supply voltage using a control knob, VR1 as follows:
(1) Turn ON the Drive and Control Units, and boot SPEL 95. The Robot must be put
into the emergency stop condition for safety. At this time, make sure that the
encoder power is being supplied by checking on the LED1 on the Manipulator’s relay
board. (The lamp must be ON.)
(2) Measure the voltage between the e5V and the GND pin on the Encoder
Signal connector of the longest motor cable in the Manipulator. (As for which pins
to measure, refer to the Manipulator manual.)
(3) If the encoder voltage is not within the range of 4.9V to 5.2V, adjust it as follows:
(4) Remove the Upper Cover of the Drive Unit by taking out the eight screws.
(5) If the measured voltage is lower than 4.9V, turn the VR1 on DPB knob “+” direction
by 1/2 track to increase the voltage. If the measure voltage is higher than 5.2V, turn
the VR1 knob “-” direction by 1/2 track to lower the voltage.
(6) Repeat the step (2) to ensure that the voltage is between “4.9V and 5.2V”.
(7) If necessary, repeat the steps (5) and (6) until the voltage is within the range of “4.9V
to 5.2V”.
(8) When the adjustment is completed, place the Upper Cover back on.
