6.5 - MOTOR PARAMETERS: P21, P25, P26, P27<br />
6.5.1 - P21 - Motor<br />
Current Setting<br />
(% IN of the<br />
switch)<br />
Sets the motor current value percentually relating to rated<br />
switch current.<br />
Monitors the overload condition according to the thermal<br />
class curve selected at P25, and protects the motor<br />
against overloads applied on the shaft.<br />
When the overload time is exceeded as defined by the<br />
thermal class protection, the motor is OFF and the HMI-<br />
3P display will show error E04.<br />
Parameter P21, P25, P26 and P27 are part of the thermal<br />
protection.<br />
To disable the thermal protection, set P21=OFF.<br />
Ex: How to set P21:<br />
1) Standard Connection<br />
IN of the switch = 170A<br />
IN of the motor = 140A<br />
IN of the motor<br />
IN of the switch =<br />
P21 = 82.3%<br />
140A<br />
170A<br />
= 0.823<br />
2) Within motor delta connection<br />
of the switch = 120A<br />
of the motor = 140A<br />
of the delta switch = 120A x 1.73 = 207.8A<br />
IN of the motor<br />
140A<br />
IN of the delta switch = 207.8A<br />
= 0.673 x of the switch<br />
P21 = 67.3% of<br />
of delta switch<br />
