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

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.

Installation and Connection

3.3.5 Motor Terminal Connections

No jumpers in place

230V

Jumper setting

460V

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.
