Motor Protection

Motor, System and Soft Starter Protection Mechanisms

The MVS incorporates extensive protection features to ensure safe operation of the motor, system and soft starter.   
Most protection features can be customised to suit the installation.    Use parameter group 4 Protection Settings to 

control the situation where the protections will activate and parameter group 16 Protection Action to select the 

soft starter's response.    The default response is to trip the soft starter.

Protection Coordination

Check protection settings on the supply side of the starter to ensure correct coordination with the parameters of 

the soft starter. .

When using fuse and main contactors, set the upstream circuit breaker protection parameters according to the 
ratings for fuse and contactor. The contactor must not open if the current is above its maximum breaking current 

value.    The fuse must act first or the upstream breakers instantaneous trip level must be less than the contactor's 

maximum breaking current level. 

If using circuit breakers only, set the soft starter's maximum instantaneous trip time < 150 ms. Always use a suitable 

external protection relay with a circuit breaker to ensure instantaneous overcurrent trip functionality.

Voltage must not be continuously maintained on the phase arms while the motor is off. Short circuit protective 
equipment must be installed in all cases.

Motor Overload Protection

The MVS offers thermal model motor overload protection which monitors the performance of the motor and 

calculates its temperature in all states.    This protection is based on the motor information programmed in 

parameter groups 1 and 9, and the thermal model adjusts itself according to the motor's recent operating history 
(including temperature rise from previous operation).

Motor Thermal Model Protection Set-up

To enable motor and starter protection using the motor thermal model, the soft starter must be programmed with 

accurate information on the motor's characteristics.   

1.

Set parameters 1B 

Locked Rotor Time, 1C Locked Rotor Current and 1D Motor Service Factor according to 

the motor datasheet.   

2.

Use instantaneous overcurrent protection (parameters 4E, 4F) to provide protection for locked rotor 

situations.    Refer to individual parameters for details.

3.

Use instantaneous overcurrent protection stage 2 (parameters 4U, 4V) to trip circuit breaker or main contactor 

in the event of extreme overcurrent situations.
