Residual hazards

Protection
Disconnect the controller before you start working on it/open it and wait for at least 3
l
of persions minutes since the power terminals U, V, W; BR0, BR1, BR2 and pins of the FIF interface
remain live for this time.
– After you have opened the motec check whether the power terminals L1, L2, L3; U, V, W;
BR0, BR1, BR2, relay outputs K11, K12, K14 and pins of the FIF interface are not live any
more.
– Even if the controller is disconnected from the mains, the relay outputs K11, K12, K14 can
carry dangerous voltage!
If you use the not open-circuit protected function "Selection of direction of rotation" via the
l
digital signal CW/CCW (C0007 = -0- ... -13-, C0410/3 ≠ 255):
– In the event of an open circuit or failure of the control voltage, the drive can change its
direction of rotation.
If you use the function "Flying-restart circuit" (C0142 = -2-, -3-) with machines with a low
l
moment of inertia and a minimum friction:
– After controller enable in standstill, the motor can start for a short time or change its
direction of rotation for a short time.
The motec heatsink temperature is > 60 °C:
l
– Direct skin contact with the heatsink results in burnings.
Controller
Depending on the controller settings, the connected motor can be overheated:
l
protection
– For instance, longer DC-braking operations.
– Longer operation of self-ventilated motors at low speed.
Overspeeds
Drives can reach dangerous overspeeds (e.g. setting of inappropriately high field
l
frequencies):
– The controllers do not offer any protection against these operating conditions. For this, use
additional components.
