S1+0 Initial Operation Mode
The value stored in the data register designated by operand S1+0 determines the frequency range of the high-frequency
initial pulse output.
0: 10 to 1,000 Hz
1: 100 to 10,000 Hz
2: 1,000 to 20,000 Hz
S1+1 Initial Pulse Frequency
The value stored in the data register designated by operand S1+1 specifies the frequency of the initial pulse output in per-
cent of the maximum of the frequency range selected by S1+0. When S1+0 is set to 0 (10 to 1,000 Hz) or 1 (100 to 10,000
Hz), valid values for operand S1+1 are 1 through 100, thus the initial pulse frequency can be 10 to 1,000 Hz or 100 to
10,000 Hz, respectively. When S1+0 is set to 2 (1,000 to 20,000 Hz), valid values for operand S1+1 are 1 through 20 and
the S1+1 value multiplied by 5 determines the initial pulse frequency, thus the initial pulse frequency can be 1,000 to
20,000 Hz.
S1+2 Creep Operation Mode
The value stored in the data register designated by operand S1+2 determines the frequency range of the low-frequency
creep pulse output.
0: 10 to 1,000 Hz
1: 100 to 10,000 Hz
2: 1,000 to 20,000 Hz
S1+3 Creep Pulse Frequency
The value stored in the data register designated by operand S1+3 specifies the frequency of the creep pulse output in per-
cent of the maximum of the frequency range selected by S1+2. When S1+2 is set to 0 (10 to 1,000 Hz) or 1 (100 to 10,000
Hz), valid values for operand S1+3 are 1 through 100, thus the creep pulse frequency can be 10 to 1,000 Hz or 100 to
10,000 Hz, respectively. When S1+2 is set to 2 (1,000 to 20,000 Hz), valid values for operand S1+3 are 1 through 20 and
the S1+3 value multiplied by 5 determines the creep pulse frequency, thus the creep pulse frequency can be 1,000 to
20,000 Hz.
S1+4 Error Status
When the start input for the ZRN1 or ZRN2 instruction is turned on, operand values are checked. When any error is found
in the operand values, the data register designated by operand S1+4 stores an error code.
Initial Operation Mode Initial Pulse Frequency (Hz)
0 or 1 Maximum frequency (Hz) selected by S1+0
× S1+1 value (%)
2 Maximum frequency (Hz) selected by S1+0 × S1+1 value (×5%)
Creep Operation Mode Creep Pulse Frequency (Hz)
0 or 1 Maximum frequency (Hz) selected by S1+2
× S1+3 value (%)
2 Maximum frequency (Hz) selected by S1+2
× S1+3 value (×5%)
Error Code Description
0 Normal
1 Operation mode designation error (S1+0 or S1+2 stores other than 0 through 2)
2 Output pulse frequency designation error (S1+1 or S1+3 stores other than 1 through 100)
