GRT1-CP1-L Positioning Unit Section 7-5
Note Each command is executed only once when the command bit is turned ON.
Command bits are not reset automatically and must be reset by the user.
Make sure to reset the command bit after execution of the command has
been completed (i.e., after the corresponding Completed Flag has turned ON
in word m+2). Also, make sure that all command bits are OFF when the Unit
is started, including when starting a new Unit after Unit replacement.

04 Counter Data Display Command Bit (See note.)
Turn ON this bit to change the register displayed in the Counter Data (words m and m+1) to the
register specified by the Register Selection Bits (bits 00 to 02 of word n+2). The specified register
will not change regardless of write actions.
05 Digital Input Enable Bit
This bit enables and disables the digital input.
OFF: The function assigned to the digital input is disabled.
ON: The function assigned to the digital input is enabled.
06 and
07
Z Input Counter Reset Mode Bits
These bits set the counter reset mode for the Z input.
Bit: 07 06
0 0 = Z input is ignored
0 1 = The counter value is reset to zero on first rising edge of the Z input.
1 0 = The counter value is reset to zero on every rising edge of the Z input.
1 1 = The counter value is reset to zero on every rising edge of the Z input if the digital input
(IN) is ON.
08 Gate Control Bit
This bit enables and disables the counter.
OFF: Counting is enabled.
ON: Counting is disabled (i.e., no pulses are counted), and the Present Counter Value will not
change in response to encoder inputs.
The Present Counter Value can be changed using a reset or preset command even when counting
is disabled.
09 Capture Command Bit (See note.)
Turn ON this bit to store the Present Counter Value in the Capture Value Register.
10 Preset Command Bit (See note.)
Turn ON this bit to set the Preset Value Register to the Present Counter Value.
11 Reset Command Bit (See note.)
Turn ON this bit to reset the Present Counter Value to 0.

13
Output 0 Control Bits
These bits control digital output 0 (OUT0).
Bit: 13 12
0 0 = Digital output 0 controlled by range 0 (LL0 and UL0).
0 1 = Digital output 0 turned OFF.
1 0 = Digital output 0 turned ON.
1 1 = Digital output 0 turned ON.
14 and
15
Output 1 Control Bits
These bits control digital output 1 (OUT1).
Bit: 15 14
0 0 = Digital output 1 controlled by range 1 (LL1 and UL1).
0 1 = Digital output 1 turned OFF.
1 0 = Digital output 1 turned ON.
1 1 = Digital output 1 turned ON.
