4.3.6 Pulse train position control mode

- To use this function, specify "05" (V2) for V/F characteristic curve selection, 1st motor (A044) and "01" (pulse train
position control mode) for the control pulse setting (P012).
- You can choose the input source of pulse train command pulse train mode setting (P013).

Terminal function
*1 In pulse train position control mode, the frequency value of a frequency command is calculated as follows:
Frequency command (Hz) =
In position control mode, the setting for the acceleration and deceleration time is invalid. (The LAD cancellation
function operates automatically to ignore acceleration and deceleration patterns.) When the position loop gain is
larger, the acceleration/deceleration time is shorter.
