measurements at different locations of the motor drive system. See
From the submenus the specific measurement is selected with
The main menu items are:
• Drive Input
Use these functions to check drive input conditions. Input voltage relates to the quality of the
mains power that feeds the drive. Input current depends on the loading of the drive and the
condition of the drive input section.
• Drive DC-Bus
Use these functions to check the DC-bus of the drive. DC-bus voltage relates to good drive
input and load conditions. DC-bus ripple relates to the drive input circuit, capacitors, and
output loading.
• Drive Output
Use these functions to check the drive output conditions. The modulated output voltage
varies with the motor speed and load. The output current depends on load and correct
function of the motor. Unbalance between the phases can cause or indicate problems. The
stress on the motor insulation can be determined by measurement of the risetime of a fast
modulation pulse.
