Device protection
ƒ All pluggable terminals can only be plugged in or unplugged when the controller is
disconnected from the power supply!
ƒ Frequent mains switching (e.g. inching mode via mains contactor) can overload and
destroy the input current limitation of the controller:
– Therefore at least 3 minutes must pass between two switch−on operations.
Motor protection
ƒ Certain drive controller settings can overheat the connected motor:
– E. g. long−time operation of the DC injection brake.
– Long−time operation of self−ventilated motors at low speeds.
Protection of the machine/system
ƒ Drives can reach dangerous overspeeds (e. g. setting of high output frequencies in
connection with motors and machines not suitable for this purpose):
– The drive controllers do not provide protection against such operating conditions.
For this purpose, use additional components.
J
