4.10. Control Terminal Connections
Example connection schematics are provided in section
7.3. Example Connection Schematics
4.10.1. +24V DC Input / Output
When the mains power is applied to the drive, terminal 1 provides a +24V DC output, maximum load 100mA. 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 ex24V 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 100mA.
4.10.2. Digital Inputs
Up to five digital inputs are available. The function of the inputs is defined by parameters P1-12 and P1-13, which are explained in
section
4.10.3. 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
8.1. Parameter Group 2 - Extended Parameters
The function of the analog input, e.g. for speed reference or PID feedback for example is defined by parameters P1-12 and P1-13.
The function of these parameters and available options are described in section

4.10.4. Analog Outputs
Two analog outputs are available, and may be used for 0 – 10 Volt Signal (max load 20mA), 0 – 20mA, 4 – 20mA or a digital
+24Volt DC, 20mA output. The parameters to select function and format are as follows.

4.10.5. Auxiliary Relay Outputs
Two relay outputs are available, which are intended to be used to switch external resistive loads up to 5A at 230V AC or 30V DC.
Relay 1 has both normally open and normally closed contacts available. Relay 2 provides a simple open or closed contact.
The relay output function may be configured using parameters P2-15 and P2-18, which are described in section
