Motor protection

ƒ Only use motors with a minimum insulation resistance of û = 1.5 kV,

min. du/dt = 5 kV/ms.

– Lenze motors meet these requirements.

ƒ When using motors with an unknown insulation resistance, please

contact your motor supplier.

ƒ Some settings of the axis module lead to an overheating of the connected

motor, e.g. longer operation of self−ventilated motors with low speeds.

ƒ Use PTC thermistors or thermostats with PTC characteristic for motor

temperature monitoring.
