4.4.2 Electric Interference is Serious
Cause
• Physical hardware
1. The drive, Lambda 5E terminal board and EX33A terminal board are not
well grounded.
2. The cable shielding layer is not well treated, that is, the shielding layer is
broken and the shielding nest is not wired to the outer metal frame.
3. The No.4 pin of M16 tow cable with 4-core air plug and follow-up
amplifier are not well connected.
4. The follow-up amplifier and the machine tool are not connected tightly
and completely.
5. The cable does not work well.
6. The machine tool is not well grounded.
• Software setting
1. Value of parameter Sensitivity is too large.
2. Value of parameters In Position Tolerance and Zero Limit Speed
Range are too small.
Solution
• Physical hardware
1. Reconnect the hardware.
2. Fix the shielding layer and wire the shielding nest to the outer metal
frame.
3. Connect the No.4 pin of M16 tow cable with 4-core air plug and the
follow-up amplifier.
The resistance value between the two should be very small, and 0 is the
best.
4. Connect the follow-up amplifier and the machine tool tightly and
completely.
5. Change the cable.
6. Find out the cause for being not well grounded, and solve it.
