GRT1-CT1(-1) Counter Units Section 7-4
Encoder Z Input or Digital Input (IN)
Note The response time is the time between the moment the A, B, or Z/IN input
turns ON or OFF and the moment the digital output is updated to the new
state. The specified response time may not be achieved during monitoring or
maintenance.
Digital Output (OUT)
Note The response time is the time between the moment the A, B, Z, or IN input
turns ON or OFF and the moment the digital output is updated to the new
state. The specified response time may not be achieved during monitoring or
maintenance.
OFF current 1.0 mA max.
Maximum input signal
frequency
60 kHz for pulse/direction counter mode
60 kHz for up/down counter mode
30 kHz for phase differential counter mode (×1, ×2, or ×4)
