Delta ASDA-A3 Series, User Manual, Page: 473 / 845

Parameters ASDA-A3
8-100
8
P2.104 P/PI torque switching command condition
Address: 02D0H
02D1H
Default:
200
Control mode: PT / PR / S / Sz
Unit: % Setting range: 1 - 800
Format: DEC Data size: 16-bit
Settings:
When the Torque command exceeds P2.104, the speed controller gain is switched from PI to P in order
to reduce response overshoot.
P2.105 Automatic gain adjustment level 1
Address: 02D2H
02D3H
Default:
11
Control mode: PT / PR
Unit:
-
Setting range: 1 - 21
Format: DEC Data size: 16-bit
Settings:
Use this parameter to adjust the bandwidth when auto-tuning. If the value is larger, the bandwidth after
auto-tuning is higher, but if the bandwidth margin is insufficient, it may cause machine jitter. If the value is
too low, the bandwidth after auto-tuning is lower, but the response is slower.
P2.105 > 11

P2.106 Automatic gain adjustment level 2
Address: 02D4H
02D5H
Default:
2000
Control mode: PT / PR
Unit: Pulse number Setting range: 1 - 50331648
Format: DEC Data size: 32-bit
Settings:
Use this parameter to adjust the maximum allowable overshoot when auto-tuning. The overshoot range
is set for either the user or the machine. If the value is larger, the maximum overshoot allowed by
auto-tuning is greater, but the response is faster. If the value is smaller, the maximum overshoot allowed
by auto-tuning is smaller, but the response is slower.
