P
Parameter function: set 0 for IP controller, 100 for PI controller, 1~99 for PDFF controller.
When using the IP controller, the motor speed does not overshoot or overshoot is small, but the response will be slower.
When using the PI controller, the motor speed will overshoot, but the response is rapid.
The PDFF controller is a combination of IP and PI controllers to reduce overshoot and speed up system response. The closer the
parameter is to 0, the stronger the effect of IP, and vice versa.

P S
Parameter function: this parameter is effective only when P4-00≠0, e.g. in the automatic gain adjustment mode is 1, 2, 3, 4. Used
to increase speed loop gain when P4-01 cannot set non-higher. Its meaning is
Speed loop gai =


In the automatic adjustment mode, the increase of the setting value can increase the servo response in the low rigidity situation.
However, the assembly has been set up to cause vibration.

P S T
Parameter function: this parameter is valid only at P4-00=1 and 2, i.e., gain auto tuning modes 1 and 2. Used to determine the
relationship between speed bandwidth and position bandwidth.
This parameter is based on the automatic control theory, that is, the speed bandwidth should be at least 4 times of the position
bandwidth. Generally, do not need to adjust.

Parameter function:
When P4-00=0, that is, the gain adjustment mode is manual mode, select the gain switching condition.
When P4-00≠ 0, the automatic gain adjustment mode, the function is invalid.
The number end H indicates that the parameter is hexadecimal numbers. Please pay attention to the communication.
P4-15 =0*H: only the position loop gain and the speed loop gain are switched;
P4-15 =00H: turn off the gain switch function;
P4-15 =01H: when DI terminal that is set for (GAIN_SEL) is changed OFF→ON;
P4-15 =02H: in position control mode, the position deviation is greater than the setting value of parameter P4-18 (with 100 ppr command
unit lag);
P4-15 =03H: in position control mode, when the speed command is greater than the setting value of parameter P4-18 (there is 10rpm
lag);
P4-15 =04H: the servo motor rotates at a speed greater than the setting value of P4-18 (with a 10rpm lag);
P4-15 =05H: the DI terminal defined as gain switching (GAIN_SEL) ON - OFF is invalid;
P4-15 =06H: in position control mode, the position deviation is less than the setting value of parameter P4-18 (with 100ppr command
unit lag);
P4-15 =07H: in position control mode, when the speed command is less than the setting value of parameter P4-18 (there is 10rpm lag);
P4-15 =08H: servo motor rotation speed is less than the setting value of parameter P4-18 (with 10rpm lag);
P4-15 =1*H: only switch the speed loop integral, PI--->P, that is, the speed loop integral action is eliminated
P4-15 =10H: switch off the integral switching function, the speed loop integral is always valid;
P4-15 =11H: DI terminal is defined as gain switching (GAIN_SEL), OFF-ON;
P4-15 =12H: in position control mode, the position deviation is greater than the setting value of parameter P4-18 (with 100ppr command
unit lag);
P4-15 =13H: in position control mode, when the speed command is greater than the setting value of parameter P4-18 (there is 10rpm
lag);
P4-15 =14H: the servo motor rotates at a speed greater than the setting value of the parameter P4-18 (with 10rpm lag);
P4-15 =15H: the DI terminal defined as gain switching (GAIN_SEL) ON - OFF is invalid.
P4-15 =16H: in position control mode, the position deviation is less than the setting value of parameter P4-18 (with 100ppr command
unit lag);
P4-15 =17H: in position control mode, when the speed command is less than the setting value of parameter P4-18 (there is 10rpm lag)
P4-15 =18H: servo motor rotation speed is less than the setting value of parameter P4-18 (with 10rpm lag).
Note☞
1. see the commands in section 6.9.4
2. with a lag, the actual value: when condition is met: P4_18+ lag value; the condition not satisfied: P4_18 - lag value

Parameter function: when the gain switching condition is satisfied, the gain varies linearly over time to the target gain (0: turn
off this function). Refer to Figure 5-15.
