9.3.3 Insulation Checks of the Motor
Use these instructions to check the insulation of the motor.
Obey the instructions of the motor manufacturer.
Procedure
1.
Disconnect the motor cable from the motor.
2.
Open the bridging connections in the motor connection box.
3.
Measure the insulation resistance of each motor winding. The voltage must be the same or higher than the motor nominal
voltage, but at least 1000 V.
4.
The insulation resistance must be >1 MΩ at the ambient temperature of 20 °C (68 °F).
5.
Connect the motor cables to the motor.
6.
Do the final insulation check on the drive side. Put all phases together and measure to the ground.
7.
Connect the motor cables to the drive.
9.4 Checks after Commissioning
9.4.1 Testing the AC Drive after Commissioning
Before starting the motor, do these checks.
•
Before the tests, make sure that it is safe to do each test.
•
Make sure that the other workers near know about the tests.
Procedure
1.
Make sure that all the START and STOP switches that are connected to the control terminals are in the STOP position.
2.
Make sure that the motor can be started safely.
3.
Set the parameters of group 1 (see VACON
application. To find the necessary values for the parameters, see the motor nameplate.
Set these parameters at a minimum:
-
Motor nominal voltage
-
Motor nominal frequency
-
Motor nominal speed
-
Motor nominal current
-
Motor cos phi
4.
Set the maximum frequency reference (that is, the maximum speed of the motor) to agree with the motor and the device
that is connected to the motor.
5.
Do the following tests in this order:
-
a.
RUN test without the load, see
-
b.
Start-up test, see
-
c.
Identification run, see
9.4.2 RUN Test without Load
Do either Test A or Test B.
•
Test A: Controls from the control terminals
•
Test B: Control from the control panel
9.4.2.1 Test A: Controls from the Control Terminals
Do this RUN test when the control mode is I/O terminals.
Procedure
1.
Turn the Start/Stop switch to ON position.
2.
Change the frequency reference (potentiometer).
