4.8. Motor Thermal Overload Protection
4.8.1. Internal Thermal Overload Protection
Optidrive Eco has internal motor overload protection (current limit) set at 110% of FLA. This level may be adjusted in P4-07. 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 P1-08
(motor rated current) for a sustained period of time. The overload accumulator will permit a sustained overload for different durations
before tripping as shown in the tables below:
Constant Torque (P4-01 > 0) Variable Torque (P4-01 = 0)
HD SD
110% 75 s 75 s 110% 75 s
150% 15 s 15 s 150% 1 s
175% 10 s – 175% –
200% 7.5 s – 200% –
Where:
HD = Heavy Duty drive selection – this is where the rated current of the motor connected to the drive is less than 75% of the drive
current rating
SD = Standard Duty drive selection – this is where the current rating of the motor connected to the drive is closely matched to the drive
current rating
When operating in Variable Torque (P4-01 = 0), the oversizing of the drive makes no difference to the available duration of the
overload condition.
NOTE
The 45kW 400V Eco model (ODV-3-540900-3…) overload capability follows that shown in the variable torque table
irrespective of the setting in P4-01.
4.8.2. Motor Thermistor Connection
Where a motor thermistor is to be used, it should be connected as follows:

 Compatible Thermistor: PTC Type, 2.5kΩ trip level.
 Use a setting of P1-13 that has Input 5 function as E-TRIP
“External Trip”, e.g. P1-13 = 6. Refer to section 8.1. Digital
Input Configuration Parameter P1-13 on page 39 for
further details.
 Enable the Motor PTC Thermistor Input function in parameter
P2-33.

4.9. 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 – 2.5mm2 / 30 – 12 AWG.
