The function of the analog input, e.g. for speed reference or PID feedback for example is defined by parameters P-15. The function of
these parameters and available options is described in section
7. Analog and Digital Input Macro Configurations on page 40
4.10.4. Digital Inputs
Up to four digital inputs are available. The function of the inputs is defined by parameters P-12 and P-15, which are explained in
section
7. Analog and Digital Input Macro Configurations on page 40
.
4.11. Motor Thermal Overload Protection
4.11.1. Internal Thermal Overload Protection
The drive has an built-in 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).
4.11.2. Motor Thermistor Connection
Where a motor thermistor is to be used, it should be connected as follows:

1
A screened (shielded) cable suitable for fixed installation with the relevant mains voltage in use. Braided or twisted type screened
cable where the screen covers at least 85% of the cable surface area, designed with low impedance to HF signals. Installation of
a standard cable within a suitable steel or copper tube is also acceptable.
2
A cable suitable for fixed installation with relevant mains voltage with a concentric protection wire. Installation of a standard cable
within a suitable steel or copper tube is also acceptable.
3
A cable suitable for fixed installation with relevant mains voltage. A shielded type cable is not necessary.
4
A shielded cable with low impedance shield. Twisted pair cable is recommended for analog signals.
5
The cable screen should be terminated at the motor end using an EMC type gland allowing connection to the motor body
through the largest possible surface area. Where drives are mounted in a steel control panel enclosure, the cable screen may be
terminated directly to the control panel using a suitable EMC clamp or gland, as close to the drive as possible. For IP66 drives,
connect the motor cable screen to the internal ground clamp.
