8.6.8 Relay Output

Relay 1
• Terminal 01: common
• Terminal 02: normal open 240 V AC
• Terminal 03: normal closed 240 V AC
Relay 2 (Not AutomationDrive FC 301)
• Terminal 04: common
• Terminal 05: normal open 400 V AC
• Terminal 06: normal closed 240 V AC
Relay 1 and relay 2 are programmed in par. 5-40
par. 5-41 On Delay, Relay , and par. 5-42
Additional relay outputs by using option module MCB 105.
8.6.9 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
adjustable frequency drive will trip on warning / alarm 27, "Brake IGBT". If the connection is closed between 104 and 105, the adjustable frequency drive
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 adjustable fre-
quency drive 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.
