24. FEEDING BY INVERTER
WARNING: CHANGE SPEED ONLY WHEN THE MACHINE IS ON.
- Feeding speed 0/30m/min is displayed on screen and can be changed by using the potentiometer after starting the
movement by the corresponding button.
- In order not to damage the inverter, wait approx. 10 seconds between turning the machine off and turning it back
on (operation carried out from the main switch).
- Important: if the electrical compartment is opened, the inverter maintains dangerous voltages for a short time also
after turning the machine off.

TC-501B is a kind of electronic equipment installed in numerical controlled lathe to examine the process and display
current coordinate values. In the operating process, sensors examine the direction and the distance, then display
process coordinate values with numeral tubes.
25.1.
SPECIFICATIONS
1. Power Input: AC (0 – 110V – 220V) 50/60HZ ± 20%.
2. Signals Input: Standard AB Square Wave Signals (DC9V–12V).
3. Safety Limit Switch: Travel Safety Proximity Switch.
25.2.
FEATURES
1. Controlled by monochip, safely and steadily.
2. Local parameters (Fixed parameters of first installation) can be setup.
3. There are two kinds of measurement units, mm and inch selectable at first installation.
4. Two ways, as follows, to set current dimension value, but the setting is forbidden in the process of motors
running.
First way: for vernier control and current value resetting.
•
Press “CLR” key to reset current coordinate value.
•
Add 0.01 once press “+” key.
•
Reduce 0.01 once press “-” key.
Second way: for setting original coordinate value.
•
Press “CLR” key persistently till the number on the tiptop digit begin to twinkle.
•
Press “+” key, then add 1 on the certain digit, which numbers circled between 0 to 9.
•
After setting, press “
-
” key to save and enter next digit.
•
The next digit begin to twinkle and on setting.
•
Repeat step 3-5 to setup.
•
After setup, press “CLR” key to exit setup.
The default value of unit is mm (mm light on). Pressing “
+
” and “
-
” key to boot-strap and enter setup.
Scale and precision: Six digits numbers displayed. The first digit shows sign (show nothing when the
number is positive number, and show “
-
” when the number is negative number) and other digits show
numbers. There are three digits before radix point and two after it.
The scale is -999.99mm – 999.99mm (-999.99 inch – 999.99 inch).
Store current data when power supply off.
