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
Display for normal operation
When a fault occurs or an alarm is active, a fault or alarm message will appear. In this case, refer to
Factory settings are in
Display for fault operation
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.
cards for each mode.
Induction motor without encoder
Induction motor with incremental encoder
Permanent magnet motor with Hiperface
encoder
Yaskawa IPM motor with incremental encoder
• For Permanent Magnet motors do not use any other control mode than Closed Loop Vector for PM
(A1-02 = 6). Using any other control mode can cause damage to the equipment or can cause dangerous
behavior.
