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.
