4.11 Test Run Checklist140 YASKAWA ELECTRIC SIEP C710616 27G YASKAWA AC Drive A1000 Technical ManualProceed to the following checklist after checking items 5 through 20.No. Checklist Page21 The should light after giving a Run command. –22 To give a Run command and frequency reference from the digital operator, press to set to LOCAL. The LO/RE key will light. 99, 10823 If the motor rotates in the opposite direction during the test run, switch two of the drive output terminals (U/T1, V/T2, W/T3) or changeparameter b1-14. 37024 In accordance with load condition, set Heavy Duty or Normal Duty mode using C6-01. Heavy Duty is the default setting. 19525 Set the correct values for the motor rated current (E2-01, E4-01, E5-03) and motor protection (L1-01) to ensure motor thermal protection. 216, 26726 If the Run command and frequency reference are provided via the control circuit terminals, set the drive for REMOTE and be sure the LO/RElight is out. 10827 If the control circuit terminals should supply the frequency reference, select the correct voltage input signal level (0 to 10 V or -10 to +10 V)or the correct current input signal level (4 to 20 mA or 0 to 20 mA). 14828 Apply the proper signal level (-10 to +10 V or 0 to 10 V) to terminal A1, A2, or A3. 14829 Apply the proper signal level (-10 to +10 V, 4 to 20 mA or 0 to 20 mA) to terminal A2. 14830 Set the level for current signal to H3-09 (set to 2 for 4 to 20 mA, or 3 for 0 to 20 mA). Set terminal A2 function to H3-10 (set to 0 forFrequency Bias). 14831 Set DIP switch S1 on the drive to “I” when using terminal A2 as current input.Set DIP switch S1 on the drive to “V” when using terminal A2 as voltage input. –32If the frequency reference is supplied via one of the analog inputs, make sure the analog input produces the desired frequency reference. Makethe following adjustments if the drive does not operate as expected:Gain adjustment: Set the maximum voltage/current signal and adjust the analog input gain (H3-03 for input A1, H3-11 for input A2, H3-07for analog input A3) until the frequency reference value reaches the desired value.Bias adjustment: Set the minimum voltage/current signal and adjust the analog input bias (H3-04 for input A1, H3-12 for input A2, H3-08 foranalog input A3) until the frequency reference value reaches the desired minimum value.257, 259
