Control Wiring - Invertek Compact 2 Series User Manual

6. Control Wiring

6.1. Control Terminal Wiring

All analog signals should be connected using suitably shielded, twisted pair cables.

Power and Control Signal cables should be routed separately where possible, and must not be routed parallel to each other.

Signal levels of different voltages e.g. 24 Volt DC and 110 Volt AC, should not be routed in the same cable.

Control Cable entries accept a single conductor, maximum size: 0.05 – 0.5mm

Default Connections
6.3. Analog Output
The analog output function may be configured using parameter P-25, which is described in section 7.4.2 Extended parameters on page 21.
The output has two operating modes, dependent on the parameter selection.

Analog Mode
o
The output is a 0 – 10 volt DC signal, 20mA max load current

Digital Mode
o
The output is 24 volt DC, 20mA max load current
6.4. Relay Output
The relay output function may be configured using parameter P-18, which is described in section 7.4.2 Extended parameters on page 21.
6.5. 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 P-16

Analog Input 2 Format Selection Parameter P-47
These parameters are described more fully in section 7.4.2 Extended parameters on page 21.
The function of the analog input, e.g. for speed reference or PID feedback for example is defined by parameters P-12 and P-15. The function of
these parameters and available options are described in section 8.3 Macro Function Guide on page 28.
6.6. Digital Inputs
Up to four digital inputs are available. The function of each input is defined by parameters P-12 and P-15, which are explained in section 8.3
Macro Function Guide on page 28.
6.7. Motor Thermistor Connection
Where a motor thermistor is to be used, it should be connected as follows:
Control Terminal Strip
1 2 3 4
6.8. Internal Thermal Overload Protection
The drive has an in-built motor thermal overload function; this is in the form of an "I.t-trP" trip after delivering >100% of the value set in P-08 for
a sustained period of time (e.g. 150% for 60 seconds).

Additional Information

Compatible Thermistor : PTC Type

Trip Level: >=2.5kΩ

Reset Level: =<1.9 kΩ

The thermistor input is monitored at all times, except during Fire Mode operation. The drive may trip
even if it is disabled.

Use suitable settings of P-12 and P-15 which have Input 3 function as External Trip, e.g. P-12 = 0, P-15 =
3. Refer to section 7 for further information.

Set P-47 = "". If this setting is not used, the drive will display "E-trp" only if the thermistor
exceeds the threshold level during operation.
