Pulse Train Input Interface <br />
4.5 Adjustments<br />
For maximum performance for a motor, it is necessary to adjust the gain.<br />
The responsiveness of the motor is changed according to the gain setting value. The gain is<br />
regulated by adjustment of the rotary switch or PC interface. Use the waveform monitor of the<br />
PC interface etc to adjust the velocity waveform and In-Position signal.<br />
4.5.1 Adjustment Parameters<br />

Commands for adjustmentFor adjustment parameter details, refer to Section 4.3.2 – Commands for<br />
Adjustment<br />
Command Command<br />
Function<br />
name<br />
33(21h) S-Shape<br />
Filter<br />
Sets the time constants of S-shape filter on pulse train command.<br />
Effective for reducing shock and vibration during load operation stoppage.<br />
However, increasing the value setting will lead to reduced synchronicity with command.<br />
47(2Fh) Gain Table Sets maximum 4 patterns of gain table. Used when switching the gain by motion in the<br />
Input Port rather than single adjustment of the gain by rotary switch.<br />
34(22h) LPF Sets the low-pass filter of velocity feedback.<br />
225(E1h) PPI Sets switching velocity of PPI control. Switches to PI control when actual velocity is less<br />
Control<br />
Switch<br />
than the set velocity and P control when greater than the set velocity. Effective for<br />
reducing the positioning time caused by accumulated deviations and for improving velocity<br />
change during fixed speed operation.<br />
226(E2h) Control The PB system utilizes Close control (PI control) during operation and Open control during<br />
Switch stoppage. As switching this control method may cause vibration during acceleration or slow<br />
Condition motion operation, set the control switch frequency with this command to determine the<br />
operation profile.<br />
