6-2. Pulse Output
z Pulse Output Function
ormally XC3 series and XC5 series PLC have 2 channels pulse output. Via different instruction to
rogram, you can realize single direction pulse output without speedup/speed-down; or you can realize
ingle direction pulse output with speedup/speed-down; or you can realize multiply-segment,
ositive/negative output and so on. The output frequency can reach 400K Hz.

ote: 1) To use pulse output, you should use PLC with transistor output. Such as XC3-14T-E or
XC3-60RT-E etc.
2) XC5-32 PLC models have 4 channels (Y0, Y1, Y2, Y3) pulse output function.
Type and application of pulse output
1、 Single direction pulse output without speedup/speed-down
• Frequency: 0~400KHz
• Output terminals: Y0 or Y1
• Output mode: sequential or limited pulse output
• Pulse number: 16 bits instructions 0~K32767
32 bits instructions 0~K2147483647
• Instructions: PLSY, PLSF
PLSY: generate certain quantity pulse with the assigned frequency
PLSF: generate sequential pulse with changeable frequency form
