4.5 Direction check Precondition:
• Inverter module is fully connected.
• The motor planned for the application is correctly connected.
• Device set to VFC mode = Voltage Frequency Control (factory
setting).
• Enter a low reference value, e.g. slow jog.
1. Test phase position of motor
connections.
2. Test encoder connection Precondition:
• Inverter module is fully connected.
• The motor with encoder planned for the application is correctly
connected.
• Device set to FOR mode = Field Oriented Regulation.
Step Action Note
1
Close ENPO contact. ENPO active enables power stage.
2
Start drive by closing STR
contact.
Motor accelerates to preset reference
3
Check direction of rotation of
drive.
With STR active, motor rotates
clockwise (2)
(1) Direction of view.
4
Brake drive by opening start
contact.
Drive brakes down to standstill.
5
Open ENPO contact.
ENPO inactive safely disables power
stage.
6
If direction is wrong, check phase
position of motor connections.
Also check the control connections:
STR > term. X2/9 (ISD00)
If the direction matches the actuation, the test is completed.
