Example connection schematics are provided in section Example Connection Schematics on page 52.
+24 V DC Input / Output
When the mains power is applied to the drive, terminal 1 provides a +24 V DC output, maximum load
100 mA. This may be used to activate digital inputs or provide power to sensors.
When no mains power is applied to the drive, the drive control electronics may be powered from an external
+24 V DC source. When powered in this way, all analog and digital I/O and communication functions remain
operative, however the motor may not be operated, which allows safe testing and commissioning of the
installation without risk of high voltage being present. When powered in this way, the drive requires up
to 100 mA.
Digital Inputs
Up to ve digital inputs are available. The function of the inputs is dened by parameters P1-12 and P1-13,
which are explained in section Control Terminal Functions on page 48.
Analog Inputs
Two analog inputs are available, which may also be used as digital Inputs if required. The signal formats are
selected by parameters as follows:
• Analog Input 1 Format Selection Parameter P2-30.
• Analog Input 2 Format Selection Parameter P2-33.
These parameters are described more fully in section Parameter Group 2 - Extended Parameters on page 56.
The function of the analog input, e.g. for speed reference or PID feedback for example is dened by
parameters P1-12 and P1-13. The function of these parameters and available options are described in section
Control Terminal Functions on page 48.
