4 Explanation of Interface Signals
4.2 PLC Input Signals (Data Type: R***)
Cont. Signal name
A Chopping error No.
[Function]
This signal notifies the user PLC of the alarm details when an alarm occurs during chopping operation.
[Operation]
Chopping error No. and details are shown below.
Error No.
0 No error
1 The number of chopping cycles is zero. (Operates when the number of cycles is 1.)
2 The speed exceeds the cutting feed clamp speed.
(The feedrate is clamped at the cutting feed clamp speed.)
3 The acceleration determined based on the parameter exceeds the value of parameter "#2002
clamp" or "#2141 chtL".
(The number of cycles decreases because the acceleration is clamped at "#2002 clamp" or "#2141
chtL")
4 The number of cycles exceeds 1056/min.
(The number of cycles for chopping is clamped at 1056/min.)
5 Chopping axis zero point return is not completed.
6 Chopping override is zero.
7 Commanded axis is the chopping axis.
8 The bottom dead center point position is zero.
9 The chopping axis is a manual feed axis.
10 Interlock
11 Stored stroke limit or stroke end
12 The function that cannot be used concurrently is valid.
13 An interference is detected in the interference check III, or an entry in the interference alarm area
occurs.
20 There is no specification for chopping.
Or the chopping function cannot be used.
21 Chopping control data area exceeds the R register area designated for the chopping control data.
Chopping control data area and compensation amount record area are overlapped.
Compensation amount record area exceeds R register's backup area (R8300 to R9799). ("Rm +
14 × N sets + 4" exceeds "9799".)
22 Multiple chopping axes are specified by the PLC interface.
23 Chopping axis is not specified by either PLC interface or parameter.
24 Compensation method is set to other than "0" or "1".
25 The mode for the compensation value fixed method is set to other than "0" (playback mode) or "1"
(record mode).
26 Data No. of the chopping control data is a negative value.
27 Chopping axis's "#2081 chclsp" (Maximum chopping speed) and "#2002 clamp" (Cutting feedrate
for clamp function) are both set to "0".
28 Chopping axis was changed during chopping operation.
(Chopping axis cannot be changed during chopping.)
29 Rotary axis was specified as chopping axis.
30 Rapid traverse override valid/invalid is set to other than "0" (invalid) or "1" (valid).
31 The setting unit of the chopping override is set to other than "0" (1%) or "1" (0.01%).
Classification A: The error is retained during chopping operation.
The error is cleared at the rising edge of the "Chopping parameter valid" signal (YC34) after the chopping con-
trol data is corrected, or when the NC is reset.
Classification B: The error is cleared after the alarm factor is removed, or when the NC is reset.
Classification C: The error is cleared at the falling edge of the "Chopping parameter valid" signal (YC34), or when the NC is reset.
The chopping control data is not enabled when this alarm occurs.
