J
PG Pulse Output Monitor Division Rate: F1-06
D
This constant is effective only when a PG-B2 PG Control Card is used.
D
It sets the division ratio used when the pulse monitor output is connected to a pulse input device.

F1-06
PG division rate (PG
pulse monitor)
x 1 to 132 -- 1 x B x B
D
The first digit in the setting (0 or 1) is n and the second two digits (01 to 32) are m. The division ratio
is calculated from n and m with the following equation:
Division ratio = ( 1+n )/m Setting Ranges n: 0, 1 m: 1 to 32
F1-06 =
m n
D
Possible division rate settings are as follows: 1/32 ≦ F1-06 ≦ 1. For example, if the division rate is 1/2
(a setting of “2”), the monitor output will be half of the number of pulses output from the PG.
J
Fault Detection Functions: F1-02 to F1-04, F1-08 to F1-11, F1-14
PG Disconnection Stopping Method: F1-02, F1-14
D
Sets the PG open-circuit detection time and stopping method that is used when a break is detected in
the PG cable (PGO).
