Generating 5136 alarm fanuc control cnc?

Answer 1

ALARM 5136 (FSSB: NUMBER OF AMPS IS SMALL)

The number of servo amplifiers recognized by the FSSB is insufficient,

compared with the number of controlled axes.

Most of the time the problem is an optical cable. When an optical cable is unplugged from the socket, there should be a red light coming out of one of the optical cables AND a red light coming out of the opposite side of the socket.

FSSB setting screen

If this alarm is issued, display the amplifier setting screen from the FSSB

setting screen. Only the servo amplifiers recognized on the FSSB are

displayed.

Optical cable or servo amplifier

The optical cable that connects together the last recognized amplifier and

the next one may be defective.

Or, either of the amplifiers connected together with that optical cable may

be defective. Check the power supplies of the amplifiers.

Power fault of a servo amplifier

This alarm may be issued if a power fault occurs in a servo amplifier. A

power fault occurs if the amplifier control power supply voltage drops,

if the +5 V conductor of the pulse coder cable is ground, or for other

reasons.

Axis control cards

The axis control cards installed on the CNC may be defective.

See Section 8.14 for explanations about the mounting location of the axis

control card.
