F_18
: Motor rated current range: 000-001~200 %
1. The electronic thermal overload protection for motor :
(1) Motor rated current = Inverter rated current x F_18
F_18 = Motor rated current / inverter rated current
(2) When the load is within 100% of the motors rated current, normal operation continues. When
the load reaches 150% of the motors rated current the operation is allowed to continue for 1
minute. (refer to curve (1) in Figure 3)
(3) After protecting the motor with the electronic thermal switch activated, the inverter is cut off
immediately. The OLI light will flash. To resume operation, push the RESET button or activate
an external reset connection wired to TB1 terminal 5 or 6.
(4) When the motor is operating at low speeds, the heat dissipation efficiency is lower. The elec-
tronic thermal activation level is also reduced. (to change from curve (1) to curve (2) in Figure 3.
Choose the appropriate F_05 setting according to the applied motor to reach the desired perfor-
mance.
2. The electronic thermal protecting for inverter :
(1) When the load is within 103% of the inverters rated current, the operation continues.
When the load reaches 150% of rated current of the inverter, the operation will con-
tinue for 1 minute. ( Refer to curve (1) of figure 3)
(2) After the activation of the electronic thermal switch, the inverter is shut off immediately. The OL2
light will flash. To resume the operation, push RESET button or activate an external reset contact on
TB1 terminal 5 or 6.
