Precautions for Correct Use
Your setting must be in accordance with the pulse string input to use. Make sure to set the
proper pulse string input (the inverter) mode selection: [CA-91]. If your setting is incorrect, the
motor could make reverse rotations or other unintended movements.
When you use the pulse string that is input in [SAP][SBP][SAN][SBN] of PG option unit as a frequency
command, set main speed input source selection, 1st-motor [AA101] to 13 (Pulse string input: Option)
and set Pulse train detection object selection [ob-10] to 00 (Pulse train detection object selection).
A pulse string given as input to PG option unit can be used as a frequency command / PID feedback
value in each control mode.
Set an input pulse frequency that corresponds to the maximum frequency to the pulse string frequency
scale [ob-12].
The pulse string input values to PG option unit can be monitored with [dA-71].
Precautions for Correct Use
• Start/End function of analog input cannot be used. To limit the pulse string input frequency,
use the pulse string frequency bias size [ob-14], the pulse string frequency upper detection
limit [ob-15], and the pulse string frequency lower detection limit [ob-16]
• When the pulse input frequency is below the pulse string frequency lower detection limit
[ob-16], it is regarded as 0 Hz in the processing.
• Slow start if the pulse string frequency lower detection limit [ob-16] is set to a high value.
