5.4.5 Brake Resistor Temperature Switch
Frame size D-E-F
Torque: 0.5-0.6 Nm (5 in-lbs)
Screw size: M3
This input can be used to monitor the temperature of an externally connected brake resistor. If the input between 104 and 106 is established, the
frequency converter will trip on warning / alarm 27, "Brake IGBT". If the connection is closed between 104 and 105, the frequency converter will trip on
warning / alarm 27, "Brake IGBT".
Normally closed: 104-106 (factory installed jumper)
Normally open: 104-105
Terminal No.
106, 104, 105
If the temperature of the brake resistor gets too high
and the thermal switch drops out, the frequency con-
verter will stop braking. The motor will start coasting.
A KLIXON switch must be installed that is `normally
closed'. If this function is not used, 106 and 104 must
be short-circuited together.
5.4.6 External Fan Supply
Frame size D-E-F
In case the frequency converter is supplied by DC or if the fan must run independently of the power supply, an external power supply can be applied.
The connection is made on the power card.
Terminal No.
