TERMINAL 7 Encoder +5VDC
Connect the encoder +5VDC to this terminal
TERMINAL 8 Channel A
Connect the encoder channel “A” to this terminal
TERMINAL 9 Channel B
Connect the encoder channel “B” to this terminal
To determine the optimal encoder line count, please follow the instructions below.
1.) Determine the motor’s no load RPM
2.) Calculate rated RPM as 80% of no load RPM
3.) Divide (#2) by 60 to get revolutions per second
4.) Determine the CNC program’s maximum step pulse frequency (in Hz)
5.) Divide (#4) by (#3), which will give you the maximum counts per revolution
6.) Divide (#5) by 4, which will give you the max line count
7.) Pick the first standard line count below (#6)
An example of using that formula with a 45kHz step pulse frequency and a maximum motor RPM of 3000:
(45,000 / 40) / 4 = 281.25
This application would be best served with a 281 or lower line count to achieve that speed with the given input frequency. A
higher line count will work and will give a higher resolution at the expense of motor speed.
STEP 2: CONNECTING THE POWER SUPPLY
IMPORTANT: Never put a switch on the DC side of the power supply! This will damage, if not destroy, your drive!
Keep the power supply leads short and use the largest wire gauge that will easily fit in the terminals. If the lead length is more
than 18” use a 1000uF capacitor across the G320X power supply terminals. Make sure your power supply can provide the peak
current the motor may draw. The power supply voltage must be between 18 VDC and 80 VDC.
TERMINAL 1 POWER GROUND
Connect the power supply (-) to this terminal.
TERMINAL 2 +18 TO 80 VDC
Connect the power supply (+) to this terminal
STEP 3: TESTING THE ENCODER
At this point the encoder should be tested for functionality. You can test the encoder on the G320X by watching the indicator
LEDs on the board.
Turn on the power supply. The FAULT indicator (red LED) should be on for 1 second and then turn off, if the required switch or
jumper is between ERR/RES and ENC+. The IN-POSITION indicator (green LED) should turn on and remain on. The POWER
indicator (green LED) should always be on. Turn the motor shaft VERY slowly by hand. The IN-POSITION indicator (green LED)
will turn off when you turn the motor more than two encoder counts. The Warn indicator (yellow LED) will turn on when you
have turned the motor more than 128 encoder counts.
The FAULT indicator (red LED) will turn on when you turn the motor past the following error limit (see option switch section).
After 1 second the FAULT light will turn off and the IN-POSITION LED will come back on.
