1.3 Residual hazards
Protection of
persons
• Before working on the motec or opening the housing, check that no voltage is applied. Wait for at least 3 minutes, since after mains switch-off
the power terminals U, V, W; BR0, BR1, BR2 and the pins of the FIF interface remain live.
– 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 motec is separated from the mains, the relay outputs K11, K12, K14 can remain live!
• If you use the not fail-safe function “Selection of direction of rotation” via the digital signal DCTRL1-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 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:
– Direct skin contact with the heatsink results in burnings.
Controller
protection
• 8200 motec 3 ... 7,5 kW (E82MV302_4B, E82MV402_4B, E82MV552_4B, E82MV752_4B):
– Cyclic connection and disconnection of the controller supply voltage at L1, L2, L3 can exceed and destroy the input current limit!
– In case of cyclic mains switching over a longer period of time three minutes have to pass between two starting operations!
• Depending on the controller settings, the connected motor can be overheated:
– at, for instance, longer DC-braking operations.
– at longer operation of self-ventilated motors at low speed.
Overspeeds • Drives can reach dangerous overspeeds (e.g. setting of inappropriately high field frequencies):
– The controllers do not offer any protection against these operating conditions. For this, use additional components.
1.4 Layout of the safety information
All safety information given in these Operating Instructions have the same layout:
