High−speed Counter/Pulse Output/ PWM Output
9.2 Specifications and Restricted Items
Restrictions for maximum counting speed/pulse output frequency
The counting speed when using the high−speed counter function will differ depending
on the counting mode as shown in the table.
Example 1:
While in the incremental input mode and using the two
channels CH0 and CH1, if CH0 is being used at 8 kHz, then
CH1 can be used up to 2 kHz.
Example 2:
While in the 2−phase input mode and using the two channels
CH0 and CH2, if CH0 is being used at 1 kHz, then CH2 can be
used up to 1 kHz.
The maximum output frequency when using the pulse output function will differ
depending on the output contact number as shown in the table.
Example 1:
When using either only Y0 or only Y1, the maximum output
frequency is 10 kHz.
Example 2:
When using the two contacts Y0 and Y1, the maximum output
frequency is 5 kHz.
When using the high−speed counter function and pulse output function, specifications
will differ depending on the conditions of use.
Example:
When using one pulse output contact with a maximum output
frequency of 5 kHz, the maximum counting speed of the
high−speed counter being used simultaneously is 5 kHz with
the incremental mode and 1 kHz with the 2−phase mode.
