5.5 Motor Thermistor Connection
When an externally mounted motor thermistor is to be used, connect as follows:
Control Terminal Strip
1
2
3
4
Additional Information
• Compatible Thermistor: PTC Type
• Trip Level: >=2.5 kΩ
• Reset Level: =<1.9 kΩ
• The thermistor input is monitored at all times and the
drive may trip even if it is disabled.
• Use suitable settings of parameter 1103 Command
Source and 9902 Digital Input Function Select which have
Input 3 function as External Trip, (1103 = 0, 9902 = 3)
Refer to Chapter 12 for further information.
• Set 1304 Analog Input 2 Format =
Ptc-th
. If this
setting is not used, the drive will display
E-trP
only
if the thermistor exceeds the threshold level during
operation.
5.6 Internal Thermal Overload Protection
The drive has an in-built motor thermal overload function; this is in the form of an
It-trP
trip after delivering >100% of
the value set in 9906 Motor Rated Amps for a sustained period of time (150% for 60 seconds).
