GRT1-CP1-L Positioning Unit Section 7-5
7-5 GRT1-CP1-L Positioning Unit
This section describes the GRT1-CP1-L Positioning Unit.
7-5-1 Specifications
General Specifications
Performance Specifications
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.
I/O Signal Specifications
The encoder A and B inputs are phase differential signals for counting. The
encoder input Z is a zero marker each revolution. The A, B and Z inputs may
be either 24 V or line driver levels according to the DIP switch setting. Refer to
Hardware Settings on page 255.

tions on page 252 for details.
Overall response time 1 ms max. (See note.)
Isolation method Photocoupler isolation between communications lines and inputs/output lines.
24-V interface: No isolation between input A, input B, input Z, digital input (IN),
and digital outputs (OUT0 and OUT1).
Line-driver interface: Isolation between inputs A, B, and Z. No isolation between
digital input (IN) and digital outputs (OUT0 and OUT1).
I/O connection method Screwless Terminal block
