VS070QS-1618MDM1 Integrated Machine Product overview
202403 (V1.0) 12
Ultra-high
speed input
terminals X0–
X1
High-speed input
terminals X2–X7
Source mode or sink mode, set through s/s terminal
External circuit resistance < 400Ω
External circuit resistance > 24kΩ
X0–X7 have digital filtering function. Filtering time: 0ms,
2ms, 4ms, 8ms, 16ms, 32ms or 64ms (selected through
user programming)
Terminals other than X0–X7 are of hardware filtering.
Filtering time: about 10ms
X0–X7: High-speed counting, interrupt, and pulse
catching
X0 and X1: Up to 50kHz counting frequency
X2 and X5: Up to 10kHz counting frequency
The input terminal act as a counter has a limit over the maximum frequency. Any
frequency higher than that may result in incorrect counting or abnormal system
operation. Make sure that the input terminal arrangement is reasonable and
external sensors used are proper.
The PLC provides an S/S terminal for selecting signal input mode among source
mode and sink mode. Connecting the S/S terminal to the +24 terminal, i.e. set the
input mode to the sink mode, enables a connection with the NPN sensor.
