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.

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
=

n )/m

1/2 (a setting of “2”), the monitor output will be half of the number of pulses output from the PG.

Sets the PG open-circuit detection time and stopping method that is used when a break is detected in
the PG cable (PGO).
