4.11. IP66 Switched Version Integrated Control Switch and Potentiometer Wiring
Optidrive P2 is optionally available with an integrated mains switch-disconnector and front mounted control switch and potentiometer.
This allows the drive to be operated directly from the front control panel, whilst also providing for options such as Hand / Auto or
Local / Remote Control etc.
The integrated switch in IP66 Outdoor models operates in parallel with drive terminal 2 (T2) and terminal 3 (T3) as digital input 1 and
digital input 2. By default, the integrated switch is enabled.

4.11.1. Disabling built-in switches
If required, the built-in control switch may be disabled using the following method:
1) Ensure the drive is stopped (Display shows “Stop”).
2) Enable Advanced Parameter Access by setting the correct value in P1-14 (default : 201).
3) Scroll down to parameter P0-01 (Display shows P0-01).
4) Press and hold “STOP” button for >1s, drive will show:

2: Pos >>DI1, Pos<<DI2
1: Switch disabled
0: Pos >>DI1, Pos <<DI1&2
5) Use “UP” or “DOWN” key to select the option:
0: Pos >>DI1, Pos <<DI1&2
means integrated switches are enabled.
1: Switch disabled
means the switches are locked/disabled.
2: Pos >>DI1, Pos<<DI2
means that Revers direction is disabled via built-in switch (can be unlocked via external enable signal
connected to DI1 – terminal 2).
6) Press the “STOP” button again to exit.
4.12. Motor Thermal Overload Protection
4.12.1. Internal Thermal Overload Protection
Optidrive P2 has internal motor overload protection (current limit) set at 150% of FLC. This level may be adjusted using 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 for a sustained period of time (e.g. 150% for 60 seconds).
4.12.2. 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 DI5/AI2 function as E-TRIP
“External Trip”, e.g. P1-13 = 6. Refer to section 7.2. Digital
Input Configuration Parameter P1-13 on page 42 for
further details.
 Enable the Motor PTC Thermistor Input function in parameter
P2-33.
