3.2.9 Local control via pushbutton
Fundamentals
With the drive in the local mode, a check is made as to whether it can be controlled using the
pushbutton and potentiometer at the drive.
Test procedure
1. The drive is switched into the local mode using the "Local-Remote switch".
2. The following operating states are set using the operator controls and monitored at the
operator panel or at the test station:
– The converter is in the local mode.
– Drive on
– Drive off
– Various points along the U/f characteristic
– Reset fault
Result
The test is passed if the corresponding operating states and specified values occur.
3.2.10 Phase offset between output voltage and current with output reactor
Fundamentals
It is tested whether the voltage per phase has a 90° phase offset with respect to the current.
Test procedure
1. The drive is switched on.
2. The phase offset is displayed between the following measuring points using an oscilloscope.
– VMA and IFA
– VMB and IFB
– VMC and IFC
Result
The test is passed if the phase offset is 90°.
