Cause that sets bit 4 (APZ) of parameter No. 1815 to 0

You can find the cause that sets bit 4 (APZ) of parameter No. 1815 to 0 by checking diagnosis Nos. 310

and 311.

Once diagnosis No. 310 or 311 is set to 1, this setting is kept unchanged until the zero point of the

Detail number for invalid servo parameter setting alarm

Indicates information that can be used to identify the location (parameter) and cause of an

invalid servo parameter setting alarm (servo alarm No. 417).

This diagnosis information is valid when the following conditions are satisfied.

• Servo alarm No. 417 has occurred.

• Bit 4 of diagnosis No. 203 (PRM) = 1

See the following table for the displayed detail numbers and the corresponding causes.

V ready-off information

This information is provided to analyze the cause of the V ready-off alarm (servo alarm

SV0401).

Convert the indicated value to a binary representation, and check bits 5 to 14 of the

binary representation.

When amplifier excitation is turned on, these bits are set to 1 sequentially from the lowest

bit, which is bit 5. If the amplifier is activated normally, bits 5 to 14 are all set to 1.

Therefore, check the bits sequentially from the lowest bit to find the first bit that is set to

0. This bit indicates that the corresponding processing could not be completed and so the

V ready-off alarm was caused.

NOTE

If only PSU becomes 1, but no change occurs, and the program

stops in a block containing a G51.2 command, the speed of an

spindle does not reach the targeted polygon synchronization

speed, for example, because bit 7 (PST) of parameter No. 7603 = 0

#6 LGE The loop gain is different between the spindles during polygon synchronization mode

NOTE

When the speed is changed during polygon synchronization mode,

LGE is set to 1 if the spindle synchronization control loop gain used

by the serial spindle control unit is different between the master

spindle and polygon synchronization axis.

Diagnosis display indicates the loop gain because this function

requires that both spindles be controlled with the same loop gain.

However, no alarm is issued even if the loop gain is different

between the spindles.

(For the serial spindle control unit, the parameters used are

changed according to the state of the CTH1 and CTH2 signals.)

SC0 Actual speed command is 0 during polygon synchronization mode with two spindles.

NOTE

Signal SC0 is not a value specified by the program. It is set to 1

under any of the following conditions:

1. When the S command value is adjusted according to the signals

related to spindle control, SSTP<Gn029.6> and SOV0-

SOV7<Gn030> and the signal related to multi-spindle control

<Gn027>, the result is 0.

2. The S command value is smaller than the spindle control

resolution (the result of multiplying the S command value by a

value of 4095/(maximum spindle speed) is less than 1).

The S command value is specified by SIND control <Gn032,

Gn033>, and it is 0.

If SC0 = 1, the spindle speed becomes 0 and bit 0 of diagnosis

display No. 471 becomes 1. In this case, the polygon

synchronization rotation ratio is impractical, but alarm PS5018 does

not occurs, because it is regarded as the result of the command.

Alarm PS5018 is cleared by a reset, but the indication of its causes remains until the

causes are cleared or the polygon synchronization mode is released.

SCU The specified speed is too low during polygon synchronization mode with two spindles.

(The unit of speed calculated internally becomes 0.)

NOTE

SCU becomes 1 also when the specified spindle speed is 0

(diagnosis display No. 470#7 = 1). In this case, however, alarm

PS5018 is not issued (because the command is 0). When

diagnosis display No. 470#7 = 0 and diagnosis display No. 471#0 =

1, alarm PS5018 occurs. Normally this does not occur with speed

at which the spindle can rotate.

QCL The polygon synchronization axis is clamped.

NOTE

QCL becomes 1, when the polygon synchronization axis receives a

command with a polygon synchronization speed that is higher than

the value specified in parameter No. 7621 and is clamped at that

speed.

SUO The specified speed is too high during the polygon synchronization mode with two

spindles.

(It is clamped to the upper limit calculated internally.)

NOTE

SUO occurs, if a result of (speed specified for the master

spindle)/(value specified at P) is higher than 59998. In other words,

the master spindle must rotate at a speed lower than 59998 min^-1

assuming P = 1.

indication of its causes remains until the alarm PS0314 is cleared by a reset.
