9-42 Function ParametersAC10 Inverterloop. Increasing KP and KI can speed up dynamic response of speed loop. However, ifproportional gain or integral gain is too large, it may give rise to oscillation.Recommended adjusting procedures:Make fine adjustment of the value starting from the manufacturer value if the manufacturersetting value cannot meet the needs of practical application. Be cautious that amplitude ofadjustment each time should not be too large.In the event of weak loading capacity or slow rising of rotary speed, increase the value of KPfirst under the precondition of ensuring no oscillation. If it is stable, increase the value of KIproperly to speed up response.In the event of oscillation of current or rotary speed, decrease KP and KI properly.In conditions of uncertainty, decrease KP at first, if there is no effect, increase KP. Then adjustKI.Note: Improper setting of KP and KI may result in violent oscillation of the system, or evenfailure of normal operation. Set them carefully.F870 PMSMback electromotiveforce (mV/rpm)0.1～999.9 (valid value betweenlines)F871 PMSMD-axis inductance(mH) 0.01～655.35F872 PMSM Q-axis inductance(mH) 0.01～655.35F873 PMSMstator resistance（Ω） 0.001～65.000 (phase resistor)For example:When F876=20, if F877=10 and F878=0, the injection current without load is 20% of ratedcurrent.When F876=20, if F877=10 and F878=10, and rated frequency is 50Hz, injection currentwithout load will decrease by a linear trend from 30 (F876+F877). When inverter runs to 5Hz(5Hz=rated frequency X F878%), injection current will decrease to 20, and 5Hz is cut -off point ofinjection current compensation without load.F880 PMSM PCEdetection time (S) 0.0～10.0 0.29.9 Communication ParameterF900 Communication Address 1~255: single inverter address0: broadcast address 1F901 Communication Mode 1: ASCII2: RTU 1F902 Stop byte Setting range: 1~2 2F903 Parity Check 0: Invalid1: Odd2: Even0F904 Baud Rate(bps)Setting range:0: 1200;1: 2400;3F876 PMSM injection current withoutload (%) 0.0～100.0 20.0F877 PMSMinjection currentcompensation without load (%) 0.0～50.0 0.0F878 PMSMcut-off point of injectioncurrent compensation without load (%) 0.0～50.0 10.0www.comoso.com |
