IdLE At power-up and in correspondence with Pr0 this message shows that no alarms are
present and the system is disabled.
run At the time of power-up and in correspondence with Pr0 this message indicates that
no alarms are present and the drive is enabled; the motor shaft may be spinning.
Er. xx In correspondence with Pr0 this message indicates that the drive has detected an

3.2 Commissioning the LVD Drive
The steps described in this section must be followed carefully when the drive is started up
for the first time.
1) Connect the motor to the drive in compliance with the wiring diagrams in the manual.
2) Make sure the drive is disabled (connector X7 pin 1 open).
3) Power up the drive.
4) The message “IdLE” appears on the display.
5) Setting basic parameters:
Pr33 evaluation (rated current)
where: InM is rated motor current at zero rpm in Ampere
InD is rated drive current in Ampere
The maximum value of Pr33 is 50.0
Pr19 evaluation (peak current)
The maximum value must be no higher than three times the value of Pr33.
