GRT1-CP1-L Positioning Unit Section 7-5
Encoder A, B, and Z
Inputs
24 V Inputs
Line Driver Inputs
Digital Input (IN)
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.
Digital Outputs
(OUT0 and OUT1)
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.
