Residual hazards
Protection of persons
z
Before working on the controller check that no voltage is applied to the power terminals, the
relay output and the pins of the FIF interface,
– because the power terminals U, V, W, +UG, -UG, BR1 and BR2 remain live for at least 3
minutes after mains switch-off.
– because the power terminals L1, L2, L3; U, V, W, +UG, -UG, BR1 and BR2 remain live when
the motor is stopped.
– because the relay outputs K11, K12, K14 can remain live when the controller is
disconnected from the mains.
z
If you use the not-open-circuit protected 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.
z
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.
z
The heatsink of the controller has an operating temperature of > 80°C:
– Direct skin contact with the heatsink results in burnings.
Controller protection
z
All pluggable connection terminals must only be connected or disconnected when no voltage
is applied!
z
Cyclic connection and disconnection of the supply voltage can overload and destroy the
input current limitation of the controller:
– In case of cyclic mains switching over a longer period of time three minutes have to pass
between two starting operations!
Motor protection
z
Depending on the controller settings, the connected motor can be overheated:
– For instance, longer DC-braking operations.
– Longer operation of self-ventilated motors at low speed.
Controller/ system protection
z
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.
Warnings!
z
The device has no overspeed protection.
z
Must be provided with external or remote overload protection.
z
Suitable for use on a circuit capable of delivering not more than 5000 rms
symmetrical amperes, 240 V maximum (240 V devices) or 500 V maximum
(400/500 V devices) resp.
z
Use 60/75 °C or 75 °C copper wire only.
z
Shall be installed in a pollution degree 2 macro-environment.
