Chapter 4 contains the following information:
• Powering up the drive with the PD1 Module installed
• LED Indicators
• Operation Modes
Powering Up the Drive After you have installed the PD1 Module, apply power to the drive
and to the connected device. The READY LED should illuminate.
If it does not, refer to Chapter 8, Troubleshooting.
LED Indicators The PD1 Module has three LEDs (see figure below) which provide
module status.
The LEDs are defined as follows:
• COMM – The COMM LED has four possible states:
Green (steady) Communication ok, data is exchanged.
Red (steady) Diagnostics failed at power-up
or fatal error.
Red (flashing) Profibus configuration fault (5 to 6 flashes).
Off No communication takes place / No power
For more details refer to Troubleshooting, Table 8.A
• FAULT – This LED tracks the fault status of the 160 Drive.
When no faults are present, the LED will be off. The LED will
illuminate (red) if a drive or an option board fault occurs.
• READY – The Ready LED will illuminate (green) whenever the
module is connected to the drive and power is applied.
