2.2 List of parameters
Notice:
When speed precontrol is active (p2534 > 0 %), the following applies:
In addition to the set dead time (p2535), internally two position controller clock cycles are effective.
When speed precontrol is inactive (p2534 = 0 %), the following applies:
No dead time is effective (p2535 and internal).
Note:
Together with p2536, the timing behavior of the closed-loop control loop can be emulated.
Description:
Sets a PT1 filter to emulate the timing behavior of the closed-speed control loop.
Dependency:
Refer to: p2535
Notice:
When speed precontrol is inactive (p2534 = 0 %), the following applies:
If a PT1 filter has been set, it is not effective.
Note:
Together with p2535, the timing behavior of the closed-loop control loop can be emulated.
Description:
Sets the signal source for the adaptation of the proportional gain of the position controller.
Dependency:
Refer to: p2538
Description:
Sets the proportional gain (P gain, position loop gain, Kv factor) of the position controller.
Dependency:
Refer to: p2537, p2539, p2555, r2557, r2558
Note:
The proportional gain is used define at which traversing velocity which following error is obtained (without precontrol)
Low proportional gain:
Slow response to a setpoint - actual value difference, the following error becomes large.
High proportional gain:
Fast response to the setpoint - actual value difference, the following error becomes small.
