4.6. Motor Thermal overload Protection.
4.6.1. 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).
4.6.2. Motor Thermistor Connection
Where a motor thermistor is to be used, it should be connected as follows :-
Control Terminal Strip Additional Information

Compatible Thermistor : PTC Type, 2.5kΩ trip level

Use a setting of P-15 that has Input 3 function as External Trip, e.g. P-15 = 3. Refer to section 7 for
further details.

4.7. Control Terminal Wiring

All analog signal cables should be suitably shielded. Twisted pair cables are recommended.

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.
 Maximum control terminal tightening torque is 0.5Nm.

Control Cable entry conductor size: 0.05 – 2.5mm 2 / 30 – 12 AWG.
