3.4.6 Incremental encoder
Motors with the additional labelling IG or IGK (e.g. 80LP/4 3D IG F) are equipped with an incremental
encoder, which is suitable for ignition protection Ex tc. This option is always delivered with an external
fan, which is also suitable for ignition protection Ex tc. Operation of the motor is only permissible if the
external fan is connected.
NOTICE
Malfunction of the drive during operation with connected incremental encoder
If the motor is operated with a connected incremental encoder, there is a risk of a motor malfunction
due to faulty connection and impermissible operating conditions of the incremental encoder.
Therefore, it is mandatory to note before commissioning
• the operating instructions of the incremental encoder with the corresponding installation and
maintenance regulations,
• the maximum permissible speed of the incremental encoder,
• the information label attached to the incremental encoder,
• the superordinate motor name plate and possibly the restricting information.
If the operating instructions are not available, contact the Getriebebau NORD service department.
