4.11 Test Run Checklist
Proceed to the following checklist after checking items 5 through 20.

To give a Run command and frequency reference from the digital operator, press
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 change
23
parameter b1-14.
24 In accordance with load condition, set Heavy Duty or Normal Duty mode using C6-01. Heavy Duty is the default setting.
25 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.
If the Run command and frequency reference are provided via the control circuit terminals, set the drive for REMOTE and be sure the LO/RE
26
light is out.
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)
27
or the correct current input signal level (4 to 20 mA or 0 to 20 mA).
28 Apply the proper signal level (-10 to +10 V or 0 to 10 V) to terminal A1, A2, or A3.
29 Apply the proper signal level (-10 to +10 V, 4 to 20 mA or 0 to 20 mA) to terminal A2.
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 for
30
Frequency Bias).
Set DIP switch S1 on the drive to "I" when using terminal A2 as current input.
31
Set DIP switch S1 on the drive to "V" when using terminal A2 as voltage input.
If the frequency reference is supplied via one of the analog inputs, make sure the analog input produces the desired frequency reference. Make
the 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, H3-07
32
for 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 for
analog input A3) until the frequency reference value reaches the desired minimum value.
