Motor protection
ƒ Depending on the controller settings, the connected motor can be overheated by:
– For instance, longer DC−braking operations.
– Longer operation of self−ventilated motors at low speed.
Protection of the machine/system
ƒ Drives can reach dangerous overspeeds (e.g. setting of high output frequencies in
connection with motors and machines unsuitable for such conditions):
– The controllers do not offer any protection against such operating conditions. Use
additional components for this purpose.
ƒ Switch contactors in the motor cable only if the controller is inhibited.
When switching contactors in the motor cable while the controller is enabled, you can
activate monitoring functions of the controller. If no monitoring function is activated,
switching is permissible.
Parameter set transfer
ƒ During the parameter set transfer (initialisation), no undefined states occur.
– Additional measures for the protection of the device or for the prevention of
unrequested and/or non−braking motor movements are not required.
ƒ If no data for the initialisation are transmitted by the L−force Controller, the i700
servo inverter uses the "Lenze setting" for the parameters.
