3.3.4 Motor Overload Protection
The COMBIVERT F5 motor control by default provides motor overload protection at 130% of
the unit’s rated output current. See tables in section 2.3 for rated output current. Two additional
motor overload protection systems are available.
Electronic Motor Overload Protection
This software function provides speed dependent I
2 t overload protection and is approved
by UL as a solid state overload protection device according to UL508C section 42 and NEC
430 Part C. The trip current is adjustable as well as whether the motor is self cooled or
blower cooled.
Motor Winding Temperature Sensor
• Connects to Terminals T1, T2. These terminals as default need to be jumpered.
• Trip resistance level 1.65...4 kOhm
• Reset resistance level 0.75...1.65 kOhm
• This function can be activated or deactivated through a software parameter. The default
setting is On.
• Do not run sensor wires in the same conduit or wire way as other control cables. These
sensor wires most likely are carrying high frequency noise from the motor.
• If the sensor wires are part of the motor cable they must be shielded independently from
the motor wires.

Jumper setting
The motor connections should always be verified for correct voltage configuration before
power is appiled. (jumpers may be in place from factory testing) The motor terminals (U,V,W)
from the indexing drive, should be connected to the motor terminals U1, V1, W1.
The ground terminal at the motor should be connected to the ground terminal on the inverter.
The motor cables should be shielded and the sheild should be connected to the inverter. The
direction of rotation of the motor can be changed by reversing any two phases. (U1 to V1,
V1 to U1)
Terminals T1&T2 need to be jumpered on the inverter if not
using a thermo sensing device. The 230VAC A-Housing
doesn’t have these terminals.
