Load test with motor
1
Connect the motor cables and check the right phase order. Also check that the motor rotates
freely.
2
Check liquid cooling system operation
3
Turn on the supply voltage and ensure that all input phases are connected to the unit.
4
Check DC link voltage by measuring with multimeter and compare the value to the one on moni-
toring page
V1.8
.
5
Select the application of your choice and set the needed parameters (see Start-up Quick Guide,
step 8 on page 2.
6
Start the operation with lower Current Limit value and long Acceleration/Deceleration times.
7
If Closed Loop control mode is used, check direction of encoder and make necessary Closed Loop
parameter settings. Check the correct operation of the encoder by running the system in open
loop and check the signals in the expander board menu.
8
Run the motor without load between minimum and maximum frequencies and check the unit
output current with a current clamp. Compare the value to the one on monitoring page
V1.4
.
9
Load the motor to nominal value if possible and repeat the current measurement. Follow the Unit
Temperature value on page
V1.9
.
