5.4.4 Brake Resistor Temperature Switch
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 trips
on warning/alarm 27, “Brake IGBT.” If the connection is
closed between 104 and 105, the frequency converter trips
on warning/alarm 27, “Brake IGBT.”
Install a KLIXON switch that is `normally closed.' If this
function is not used, short circuit 106 and 104 together.
Normally closed: 104-106 (factory installed jumper)
Normally open: 104-105
Terminal No. Function
106, 104, 105 Brake resistor temperature switch.
Table 5.79 Terminals for Brake Resister Temperature Switch
NOTICE
If the temperature of the brake resistor gets too high
and the thermal switch drops out, the frequency
converter stops braking. The motor starts coasting.
5.4.5 External Fan Supply
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. Function
100, 101
102, 103
Auxiliary supply S, T
Internal supply S, T
Table 5.80 External Fan Supply Terminals
The connector located on the power card provides the
connection of line voltage for the cooling fans. The fans
are connected from factory to be supplied from a common
AC line (jumpers between 100-102 and 101-103). If external
supply is needed, the jumpers are removed and the supply
is connected to terminals 100 and 101. Use a 5 Amp fuse
for protection. In UL applications, use a LittelFuse KLK-5 or
equivalent.
