‹ Before Power Up
The following points should be checked carefully before the power is switched on.
•
Check if the power supply meets the inverter specification.
•
Check if the power supply cables are tightly connected to the right terminals (L1, L2, L3).
•
Check if the motor cables are tightly connected to the right terminals on the inverter side (U, V, W) as well
as on the motor side.
•
Check if the braking unit/braking resistor is connected correctly.
•
Check if the Inverter control circuit terminal and the control device are wired correctly.
•
Set all Inverter control circuit terminals to OFF.
•
When a PG card is used, check if it is wired correctly.

Display after Power Up
After normal power up without any problems the operator display shows the following messages
When a fault occurs or an alarm is active, a fault or alarm message will appear. In this case, refer to page 28,
Factory settings are in bold. .
‹ Control Mode Selection
As the first thing after power up one of the four control modes must be selected depending on the machine
type. The Closed Loop Vector modes require PG feedback cards.
Table 4 shows the required/possible PG
cards for each mode.
Table 4 Control Mode Selection
Display for normal operation The Baseblock message blinks.
Display for fault operation
A fault or alarm message is shown on the
display.
The example shows a low voltage alarm.
