Position Control Mode (P) - Mitsubishi Electric MR-J5 Series User Manual

Position control mode (P)

With the pulses to be inputted to the servo amplifier, the speed can be controlled. [Pr. PA01.0 Control mode selection] can be
operated when set to the initial value "0" (Position control mode).
Set the logic of the positioning module and the command pulse of the servo amplifier as follows.
• Q series/L series/R series positioning module
Signal type
Open-collector type
Differential line driver type
*1 For Q, L, and R series, the logic means the N-side waveform. Therefore, reverse the input pulse logic of the servo amplifier.
• F series positioning module
Signal type
Open-collector type
Differential line driver type
Pulse train input
■Input pulse waveform selection
The input command pulses can be inputted in three different forms, and either of the positive or negative logic can be
selected. Set the command pulse train form in [Pr. PA13 Command pulse input form].
■Connection and waveform
• Open-collector type
The following section explains about the case where the input waveform is set to negative logic and forward/reverse rotation
pulse train, [Pr. PA13.0 Command input pulse train - Form selection] is set to "0" (Forward/reverse rotation pulse trains), and
[Pr. PA13.1 Pulse train logic selection] is set to "1" (negative logic).
