Power is being properly supplied to SI-P3/V, and SI-P3/V has completed its
hardware self-diagnostics check
• The drive has no power supply
• SI-P3/V and drive are not connected properly and/or there is no power
supplied to the SI-P3/V
• An internal, self-diagnostic error occurred in the SI-P3/V
Self-diagnostics error occurred in the SI-P3/V
Connection error between SI-P3/V and drive. This includes node address
setting errors to parameter F6-30 on the drive side
Drive and SI-P3/V are properly connected
Normal send/receive between SI-P3/V and PROFIBUS-DP master
There is a problem establishing communication between SI-P3/V and the
PROFIBUS-DP master
Communication-related parameters are being set or initialized by the
PROFIBUS-DP master.
Communication parameter error from PROFIBUS-DP master
LED is off once the PROFIBUS-DP master is finished setting
communication-related parameters
