Sporadic Error Message F04 with Linear Measuring Systems

With linear measuring systems sporadic errors F04, have been observed. A possible solution could be the use of a double shielded signal cable. Connect the inner shield one one end to the outer shield (wide area connection) and connect the outer shield on both ends to ground.

If these measures don't help, you can try one of the following ground techniques:

  • connect X6 (PC/CAN) pin 5 with the servo amplifier housing
  • connect X2 (RESOLVER) pin 1 with the servo amplifier housing
  • connect X1 (ENCODER) pin 2 with the servo amplifier housing
