Encoder division output function
Only in case of having encoder division output option card, this function is available. When
connecting encoder output with pulse input device of peripheral equipment, set division

Encoder division output option card makes 1 output pulse, calculating encoder division input
option card when input pulse as PAR_31 reaches the number as much as division ratio set by a
user. Phase relation of output A, B pulses is set to maintain same as input A, B pulses, and
division ratio can be set within the range from 1(1 output pulse per 1 input pulse) to 1/128(one
output pulse per 128 input pulses).
Setting range of PAR_31 is from 0001 to 1128 and can set the values of a denominator and
numerator of division ratio. Value above 1 as division ratio is not available, only 1 and 2 are
available as a numerator. When the number in thousands unit is N among setting values of
PAR_31, and the number below thousands is M(PAR_31 setting value = N
´
1000 + M), division
ratio is calculated as below.
division = (1+N)/M
Setting range : N(0 , 1), M(1 ~ 128)
PAR_31 = [] [] [] []
When the value of PAR_31 is below 1000(N=0), a numerator of division ratio is 1. When
above 10000(N=1), it is 2. For example, when the value of PAR_31 is 15, division ratio is 1/15.
When the value of PAR_31 is 1015, it is 2/15. Also, you can set division ratio up to 1/128.
Since setting with the value above 1is not available, please use Up and Down keys of Keypad.
When increasing the value of PAR_31 by Up key, PAR_31 values will increase such as 1
