MELSEC-Q pulse I/O and counter modules

(12/31/2016)

High Speed Counter Modules

These modules provide a capability for the CPUs to sense high frequency pulse trains as would be found in motion control and similar applications. Typically these modules would be linked to encoders to provide a closed loop of position sensing on a motion axis.

Key Features:

  • Module set-up via menus in GX Works2;
    no programming required
  • External selection of count function capability
  • Up to 0.5MHz count frequency (depending on model)
  • 32 bit count range
  • Single phase and quadrature input
  • Preset count functions (linear, ring, sample, periodic)
  • Built-in outputs for direct actuation of external processes
  • CW/CCW detection

Notes:

  1. Counting speed switch setting can be done using the switch setting.
  2. Note that the count may be done incorrectly by inputting pulses whose phase difference is small between the phase A pulse and phase B pulse. To check the input waveform of the phase A pulse and phase B pulse, or to check phase difference between the phase A pulse and phase B pulse, refer to User’s Manual
  3. The counting speed is affected by the pulse rise/fall time. The number of pulses that can be counted depending on the counting speed is listed below. Note that the count may be done incorrectly by counting pulses with long rise/fall time.
